Description

地理情報システムおよび数値データの可視化用プログラムGeographic information system and numerical data visualization program
　本発明は、地理情報システムおよび数値データの可視化用プログラムに関し、特に、数値またはその計算結果を地図上に可視化できるようにした地理情報システムに用いて好適なものである。 The present invention relates to a geographic information system and a numerical data visualization program, and is particularly suitable for use in a geographic information system in which a numerical value or a calculation result thereof can be visualized on a map.
　近年、多くのデータを解析し、その解析結果をビジュアルに分かりやすく示す可視化ソフトが注目されている。可視化ソフトの１つとして、数値データを地図上に可視化できるようにした地理情報システム（ＧＩＳ：Geographic Information System）と呼ばれるツールが提供されている。この地理情報システムを用いれば、例えば、都道府県や市区町村などの地域別に数値データを集計して、その集計結果を地域別に色分けされた地図に表示することが可能である。また、顧客や販売に関する数値データを地域別に分析し、ビジネスに関する地理的なトレンドやパターンなどを地図上に可視化することも可能である。 In recent years, visualization software that analyzes a lot of data and shows the result of the analysis visually is drawing attention. As one of the visualization software, a tool called a geographic information system (GIS: Geographic Information System) that enables numerical data to be visualized on a map is provided. If this geographic information system is used, for example, it is possible to aggregate numerical data for each region such as prefectures and municipalities, and display the result on a map color-coded for each region. It is also possible to analyze numerical data related to customers and sales by region and visualize geographical trends and patterns related to business on a map.
　また、画面上に地図を表示させ、所定の入力操作に従って、地図上に矢印グラフを表示させるようにした技術も存在する（例えば、特許文献１参照）。この特許文献１に記載の技術では、物理量を入力するとともに、グラフの始点および終点の表示位置を入力すると、当該入力された物理量に応じたサイズの矢形状のグラフが、当該入力された表示位置に表示されるようになっている。また、画面上の所定の範囲を拡大すべき範囲として指定したときに、指定された範囲に複数のグラフが含まれる場合、各グラフの幅の比を保持しながら、上記指定された範囲が拡大表示されるようになっている。 Also, there is a technique in which a map is displayed on a screen and an arrow graph is displayed on the map according to a predetermined input operation (see, for example, Patent Document 1). In the technique described in Patent Document 1, when a physical quantity is input and a display position of a start point and an end point of a graph is input, an arrow-shaped graph having a size corresponding to the input physical quantity is displayed as the input display position. Is displayed. Also, when the specified range on the screen is specified as the range to be expanded and the specified range includes multiple graphs, the specified range is expanded while maintaining the width ratio of each graph. It is displayed.
　また、ユーザから入力された設定条件に基づいて、ユーザが所望する位置または範囲における生活環境を解析した解析情報あるいは生活環境を評価した評価情報を生成し、解析結果や評価結果を地図上に重ね合わせて表示するようにした技術も提案されている（例えば、特許文献２参照）。この特許文献２に記載の技術では、生活環境に対する評価として、エリア評価およびポイント評価の２つの評価を提供することが可能である。 Also, based on the setting conditions input by the user, the analysis information analyzing the living environment at the position or range desired by the user or the evaluation information evaluating the living environment is generated, and the analysis result and the evaluation result are superimposed on the map. There has also been proposed a technique for displaying them together (for example, see Patent Document 2). With the technique described in Patent Document 2, it is possible to provide two evaluations, an area evaluation and a point evaluation, as evaluations for the living environment.
　エリア評価とは、特定のエリア全体に対する生活環境評価である。エリア評価を行う場合、ユーザは、評価したい地図上の範囲を設定することが可能である。一方、ポイント評価とは、例えばあるマンションの位置というような地図上の位置とその周辺に関する生活環境評価である。ユーザは、地図の縮尺を拡大あるいは縮小したり、表示する地域を移動させたりして、地図上の所望の位置をクリックすることにより、評価の対象とするポイントを指定することが可能である。 Area evaluation is a living environment evaluation for a specific area as a whole. When performing area evaluation, the user can set a range on a map to be evaluated. On the other hand, the point evaluation is a living environment evaluation regarding a position on a map such as the position of a certain apartment and its surroundings. The user can designate a point to be evaluated by enlarging or reducing the scale of the map or moving a displayed area and clicking a desired position on the map.
　さらに、地図と数値シミュレーション結果とを表示する際に、地図の一部を拡大することによって変更した表示範囲に応じて、データを詳細化するようにした技術も提案されている（例えば、特許文献３参照）。具体的には、表示範囲として広域を指定しているときは４×４メッシュに地図を分割して数値をシミュレートし、一部を拡大して狭域を指定しているときは１０×１０メッシュに分割して数値をシミュレートする。数値シミュレーション解析では、解析対象領域をより多くのメッシュに分割してシミュレートする方が計算精度は向上するため、狭域の計算結果を選定することにより、計算精度の向上を図ることが可能とされている。 Furthermore, when displaying a map and a numerical simulation result, a technique has been proposed in which data is refined according to a display range changed by enlarging a part of the map (for example, Patent Documents). 3). Specifically, when a wide area is designated as the display range, the map is divided into 4 × 4 meshes to simulate numerical values, and when a part is enlarged and a narrow area is designated, 10 × 10 Divide into meshes to simulate numerical values.

　上記特許文献１～３によれば、地図を拡大／縮小したり、地図の表示範囲を移動させたりしながら、数値データの解析結果（グラフやシンボル等）を地図上に可視化して表示することが可能である。しかしながら、特許文献１の場合は、地図を拡大すると、それに合わせて矢印のグラフも拡大して表示されるだけである。そのため、拡大した表示範囲に合わせて別の解析結果を地図上に表示させるためには、所定の入力操作（解析対象とする物理量の入力や始点および終点の表示位置の入力など）を改めて行わなければならず、非常に面倒であった。 According to Patent Documents 1 to 3, the numerical data analysis results (graphs, symbols, etc.) are visualized and displayed on the map while the map is enlarged / reduced or the display range of the map is moved. Is possible. However, in the case of Patent Document 1, when the map is enlarged, the arrow graph is also enlarged and displayed accordingly. Therefore, in order to display another analysis result on the map in accordance with the enlarged display range, a predetermined input operation (such as input of a physical quantity to be analyzed and input of display positions of start and end points) must be performed again. It was very troublesome.
　特許文献２の場合は、任意のエリアや任意のポイントを指定して行った数値解析の結果を可視化することが可能である。また、特許文献３の場合は、地図をズーミングして設定した対象領域での数値解析の結果を可視化することが可能である。しかしながら、特許文献２，３の場合は何れも、地図上の領域を矩形の細かいメッシュ単位で区切り、１または複数のメッシュで数値計算した結果を可視化するようになっている。そのため、このメッシュ単位で規定される地図上の矩形領域（その大きさを拡縮することは可能）でしか数値計算の結果を可視化することができず、地理的領域以外の要素を単位として数値計算した結果を可視化することができないという問題があった。 In the case of Patent Document 2, it is possible to visualize the result of numerical analysis performed by designating an arbitrary area or an arbitrary point. In the case of Patent Document 3, it is possible to visualize the result of numerical analysis in the target area set by zooming the map. However, in each of Patent Documents 2 and 3, the region on the map is divided into rectangular fine mesh units, and the result of numerical calculation using one or more meshes is visualized. Therefore, the result of numerical calculation can be visualized only in the rectangular area on the map defined by this mesh unit (its size can be enlarged / reduced), and numerical calculation is performed in units other than the geographical area. There is a problem that the result cannot be visualized.
　本発明は、このような問題を解決するために成されたものであり、面倒な入力操作を行うことなく、地理的領域およびそれ以外の要素を単位として数値計算した結果を地図上に可視化することができるようにすることを目的とする。 The present invention has been made to solve such a problem, and visualizes the result of numerical calculation on a map with a geographical region and other elements as units without performing troublesome input operations. The purpose is to be able to.
　上記した課題を解決するために、本発明では、地図上の地理的領域に基づく数値計算単位を示したレイヤ、および、地図上に存在する施設に基づく数値計算単位を示したレイヤを用意し、その中から何れか所望のレイヤを指定するユーザ操作を受け付ける。そして、施設の名称、施設が存在する位置、および施設に関する数値を有して成る計算対象データを記憶したデータベースの中から、指定されたレイヤにより示されている数値計算単位に基づいて特定されるデータを取得して所定の数値計算を行い、その計算結果を地図上に可視化して表示させるようにしている。 In order to solve the above-mentioned problem, in the present invention, a layer showing a numerical calculation unit based on a geographical area on a map and a layer showing a numerical calculation unit based on a facility existing on the map are prepared, A user operation for designating any desired layer is accepted. And it specifies based on the numerical calculation unit shown by the designated layer from the database which memorize | stored the calculation object data which has the name of a facility, the position where a facility exists, and the numerical value regarding a facility. Data is acquired, predetermined numerical calculations are performed, and the calculation results are visualized and displayed on a map.
　上記のように構成した本発明によれば、ユーザが所望のレイヤを指定するための操作をするだけで、その指定されたレイヤに従って特定される地理的領域または施設を単位として数値計算が行われ、その数値計算の結果が地図上に可視化して表示されることとなる。指定するレイヤや地理的領域を変えれば、それに合わせて数値計算単位も自動的に変更され、変更後の数値計算単位で数値計算した結果が地図上に可視化して表示される。これにより、ユーザが面倒な入力操作を行うことなく、地理的領域およびそれ以外の施設といった要素を単位として数値計算した結果を地図上に可視化することができる。 According to the present invention configured as described above, numerical calculations are performed in units of geographical areas or facilities specified according to the specified layer, simply by the user performing an operation for specifying the desired layer. The result of the numerical calculation is visualized and displayed on the map. If the specified layer or geographical area is changed, the numerical calculation unit is automatically changed accordingly, and the numerical calculation result in the changed numerical calculation unit is visualized and displayed on the map. As a result, it is possible to visualize on the map the result of the numerical calculation using elements such as the geographical area and other facilities as a unit without a troublesome input operation by the user.

　以下、本発明の一実施形態を図面に基づいて説明する。図１は、本実施形態による地理情報システムの構成例を示すブロック図である。図１に示す地理情報システムは、数値またはその計算結果を地図上に可視化できるようにしたシステムであって、ズーム操作受付部１、スクロール操作受付部２、ズーミング部３、スクロール部４、データ特定部５、対象データ取得部６、可視化処理部７、地図データ記憶部１１、レイヤ情報記憶部１２、計算対象データ記憶部１３およびディスプレイ１４を備えている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a geographic information system according to the present embodiment. The geographic information system shown in FIG. 1 is a system in which a numerical value or a calculation result thereof can be visualized on a map, and includes a zoom operation reception unit 1, a scroll operation reception unit 2, a zooming unit 3, a scroll unit 4, and data identification. Unit 5, target data acquisition unit 6, visualization processing unit 7, map data storage unit 11, layer information storage unit 12, calculation target data storage unit 13, and display 14.
　このうち、ズーム操作受付部１、スクロール操作受付部２、ズーミング部３、スクロール部４、データ特定部５、対象データ取得部６および可視化処理部７は、例えばマイクロコンピュータによって実現される機能構成である。すなわち、これらの各機能ブロック１～７は、実際にはコンピュータのＣＰＵ、ＲＡＭ、ＲＯＭなどを備えて構成され、ＲＡＭやＲＯＭ、ハードディスクまたは半導体メモリ等の記録媒体に記憶されたプログラムが動作することによって実現される。 Among these, the zoom operation receiving unit 1, the scroll operation receiving unit 2, the zooming unit 3, the scroll unit 4, the data specifying unit 5, the target data acquiring unit 6 and the visualization processing unit 7 are functional configurations realized by, for example, a microcomputer. is there. That is, each of these functional blocks 1 to 7 is actually configured by including a CPU, RAM, ROM, etc. of a computer, and a program stored in a recording medium such as RAM, ROM, hard disk, or semiconductor memory operates. It is realized by.
　地図データ記憶部１１は、ディスプレイ１４に地図を表示させるための地図データを記憶している。この地図データは、例えば全世界を網羅するエリアのデータを有しており、国や地域を特定することが可能な情報を含んでいる。例えば、日本を例に挙げると、国、都道府県、市区町村を特定することが可能な情報を含んでいる。 The map data storage unit 11 stores map data for displaying a map on the display 14. This map data has, for example, data for an area covering the entire world, and includes information that can specify a country and a region. For example, taking Japan as an example, it includes information that can specify a country, a prefecture, and a city.
　レイヤ情報記憶部１２は、地図上の地理的領域に基づく数値計算単位を示したレイヤ、および、地図上に存在する施設に基づく数値計算単位を示したレイヤのそれぞれについて、数値計算単位を表したレイヤ情報を記憶する。地理的領域に基づく数値計算単位を示したレイヤに関しては、地図上の最広域レベルから最狭域レベルまで複数段階の地理的領域に従って数値計算単位を示した複数のレイヤに関するレイヤ情報を記憶する。 The layer information storage unit 12 represents the numerical calculation unit for each of the layer indicating the numerical calculation unit based on the geographical area on the map and the layer indicating the numerical calculation unit based on the facility existing on the map. Store layer information. Regarding the layer indicating the numerical calculation unit based on the geographical area, the layer information regarding the plurality of layers indicating the numerical calculation unit is stored in accordance with a plurality of stages of the geographical area from the most wide area level to the narrowest area level on the map.
　本実施形態において、最広域レベルのレイヤは、例えば日本、中国、韓国といった国別の数値計算単位を示したレイヤである。最狭域レベルのレイヤは、例えば日本で言えば、市区町村別の数値計算単位を示したレイヤである。日本の場合、最広域レベルと最狭域レベルとの間に、都道府県別の数値計算単位を示した中間レベルのレイヤが存在する。 In the present embodiment, the layer of the widest level is a layer indicating a numerical calculation unit for each country such as Japan, China, and Korea. For example, in Japan, the narrowest level layer is a layer indicating a numerical calculation unit for each municipality. In the case of Japan, there is an intermediate level layer indicating a numerical calculation unit for each prefecture between the widest area level and the narrowest area level.
　また、本実施形態において、施設に基づく数値計算単位を示したレイヤは、計算対象データ記憶部１３にデータベースとして記憶された計算対象データに含まれている施設を数値計算単位としたレイヤである。例えば、計算対象データ記憶部１３に記憶されている計算対象データが、あるチェーン店の店舗別の売上データである場合、施設とは店舗のことであり、施設に基づく数値計算単位を示したレイヤとは、個々の店舗または複数の店舗かなるグループを数値計算単位として示したレイヤのことである。 In the present embodiment, the layer indicating the numerical calculation unit based on the facility is a layer in which the facility included in the calculation target data stored as a database in the calculation target data storage unit 13 is the numerical calculation unit. For example, when the calculation target data stored in the calculation target data storage unit 13 is sales data for each store of a certain chain store, the facility is a store, and a layer indicating a numerical calculation unit based on the facility The term “layer” indicates an individual store or a group of a plurality of stores as a numerical calculation unit.
　図２は、レイヤ情報記憶部１２に記憶されるレイヤ情報の一例を示す図である。図２（ａ）は、最広域レベルのレイヤに関するレイヤ情報を示しており、全世界に存在する複数の国の名称が記憶されている。以下、この最広域レベルのレイヤを「国別レイヤ」と称する。図２（ｂ）～（ｄ）は、国の一例として日本に関するレイヤ情報を示すものである。 FIG. 2 is a diagram illustrating an example of layer information stored in the layer information storage unit 12. FIG. 2A shows layer information relating to the layer of the widest level, and names of a plurality of countries existing all over the world are stored. Hereinafter, this widest level layer is referred to as a “country layer”. 2B to 2D show layer information relating to Japan as an example of a country.
　図２（ｂ）は、日本における中間レベルのレイヤに関するレイヤ情報を示しており、日本国内に存在する都道府県の名称が記憶されている。以下、この中間レベルのレイヤを「都道府県別レイヤ」と称する。図２（ｃ）は、最狭域レベルのレイヤに関するレイヤ情報を示しており、一例として東京都内に存在する市区町村の名称が記憶されている。以下、この最狭域レベルのレイヤを「市区町村別レイヤ」と称する。図２（ｄ）は、施設のレイヤに関するレイヤ情報を示しており、一例として特定の区内に存在する複数の店舗の名称が記憶されている。以下、これを「店舗別レイヤ」と称する。 FIG. 2 (b) shows layer information relating to an intermediate level layer in Japan, in which names of prefectures existing in Japan are stored. Hereinafter, this intermediate level layer is referred to as a “prefecture-specific layer”. FIG. 2C shows layer information relating to the layer of the narrowest area level, and, as an example, names of municipalities existing in Tokyo are stored. Hereinafter, this narrowest level layer is referred to as a “city-specific layer”. FIG. 2D shows layer information related to a facility layer, and stores names of a plurality of stores existing in a specific ward as an example. Hereinafter, this is referred to as a “store-specific layer”.
　図２（ａ）～（ｃ）に示す地理的領域に関するレイヤ情報は、あらかじめ決められた情報が記憶されている。一方、図２（ｄ）に示す店舗別レイヤのレイヤ情報は、計算対象データ記憶部１３に記憶された計算対象データの内容に応じて設定される。例えば、計算対象データ記憶部１３から店舗名のデータを読み出し、当該読み出した店舗名のデータを用いて店舗別レイヤのレイヤ情報を設定してレイヤ情報記憶部１２に記憶させる。 As the layer information regarding the geographical area shown in FIGS. 2A to 2C, predetermined information is stored. On the other hand, the layer information of the store-specific layer shown in FIG. 2D is set according to the contents of the calculation target data stored in the calculation target data storage unit 13. For example, the store name data is read from the calculation target data storage unit 13, the layer information of the store-specific layer is set using the read store name data, and is stored in the layer information storage unit 12.
　なお、ここでは地理的領域に関するレイヤを３階層に分ける例について説明しているが、この数に限定されるものではない。例えば、市区町村別レイヤを市区別のレイヤと町村別のレイヤとに分けてもよい。また、国別レイヤと都道府県別レイヤとの間に、関東地方、東北地方といった地方別のレイヤを設定するようにしてもよい。 In addition, although the example which divides | segments the layer regarding a geographical area into three layers is demonstrated here, it is not limited to this number. For example, the municipality layer may be divided into a city distinction layer and a municipality layer. Further, a regional layer such as the Kanto region or the Tohoku region may be set between the country layer and the prefecture layer.
　計算対象データ記憶部１３は、施設の名称、施設が存在する位置、および施設に関する数値を有して成る計算対象データをデータベースとして記憶する。図３は、計算対象データ記憶部１３に記憶される計算対象データの一例を示す図である。図３の例では、施設の一例として「店舗名」、当該店舗が存在する位置の一例として「住所」、当該店舗に関する数値の一例として月別の「売上」を項目として有するデータベースを示している。 The calculation target data storage unit 13 stores calculation target data including a name of a facility, a position where the facility exists, and a numerical value related to the facility as a database. FIG. 3 is a diagram illustrating an example of calculation target data stored in the calculation target data storage unit 13. In the example of FIG. 3, a database having “store name” as an example of the facility, “address” as an example of the position where the store exists, and “sales” by month as an example of numerical values related to the store is shown.
　図１に示す例では、以上説明した地図データ記憶部１１、レイヤ情報記憶部１２および計算対象データ記憶部１３を本実施形態の地理情報システムが備える構成を示しているが、本発明はこれに限定されない。すなわち、地図データ記憶部１１、レイヤ情報記憶部１２および計算対象データ記憶部１３の一部または全部は、地理情報システムとは異なる外部のシステム（図示せず）またはインターネット上のサーバ装置（図示せず）が備える構成であってもよい。 In the example illustrated in FIG. 1, the map data storage unit 11, the layer information storage unit 12, and the calculation target data storage unit 13 described above are included in the geographic information system of the present embodiment. It is not limited. That is, some or all of the map data storage unit 11, the layer information storage unit 12, and the calculation target data storage unit 13 are external systems (not shown) different from the geographic information system or server devices on the Internet (not shown). May be included.
　ズーム操作受付部１は、ディスプレイ１４に表示される地図に対するユーザによるズーム操作（ズームイン操作およびズームアウト操作）を受け付ける。ズーミング部３は、ズーム操作受付部１により受け付けられたユーザ操作に応じて、可視化処理部７を通じてディスプレイ１４に表示中の地図に対してズーミングの処理を行う。なお、ズーム操作受付部１は、本発明のレイヤ指定受付部に相当するものである。すなわち、ズーム操作受付部１は、地図に対するズーム操作を通じて、レイヤ情報記憶部１２にレイヤ情報として記憶されている複数のレイヤの中から何れかのレイヤの指定を受け付ける。 The zoom operation accepting unit 1 accepts a zoom operation (zoom-in operation and zoom-out operation) performed by the user on the map displayed on the display 14. The zooming unit 3 performs a zooming process on the map being displayed on the display 14 through the visualization processing unit 7 in accordance with the user operation received by the zoom operation receiving unit 1. The zoom operation receiving unit 1 corresponds to the layer designation receiving unit of the present invention. That is, the zoom operation accepting unit 1 accepts designation of any one of a plurality of layers stored as layer information in the layer information storage unit 12 through a zoom operation on the map.
　例えば、図２のように４つのレイヤを有する場合、地図を４段階でズーミングすることができるようにしておく。そして、最もズームアウトして全世界の地図を表示したときは、図２（ａ）に示す国別レイヤを指定したものとする。また、そこから１段階ズームインして特定国（例えば、日本）の地図を表示したときは、図２（ｂ）に示す都道府県別レイヤを指定したものとする。また、さらに１段階ズームインして特定の都道府県（例えば、東京都）の地図を表示したときは、図２（ｃ）に示す市区町村別レイヤを指定したものとする。また、市区町村別レイヤまでズームインした後、さらにズームインするための操作をしたときは、図２（ｄ）に示す店舗別レイヤを指定したものとする。 For example, when there are four layers as shown in FIG. 2, the map can be zoomed in four stages. When the map is zoomed out most and a map of the whole world is displayed, it is assumed that the country-specific layer shown in FIG. Further, when a map of a specific country (for example, Japan) is displayed by zooming in one step from there, it is assumed that the prefecture-specific layer shown in FIG. Further, when a map of a specific prefecture (for example, Tokyo) is displayed by further zooming in one step, it is assumed that the municipality layer shown in FIG. In addition, when an operation for further zooming in is performed after zooming in on a city-specific layer, it is assumed that the store-specific layer shown in FIG.
　なお、ここに説明した方法は最もシンプルな方法を例示したものであって、これに限定されるものではない。例えば、レイヤの数と、ズーミング可能な段階（レベル）の数とを必ずしも一致させる必要はなく、ズーミングは多段階でシームレスに行うことができるようにしてもよい。以下では、このようにズーミングをシームレスに行う場合について説明する。 Note that the method described here is an example of the simplest method, and is not limited to this. For example, the number of layers and the number of stages (levels) at which zooming can be performed are not necessarily matched, and zooming may be performed seamlessly in multiple stages. Hereinafter, a case where the zooming is performed seamlessly in this way will be described.
　レイヤの数よりもズーミングのレベルの数を多くする場合、例えば、どのレベルのズーミングでどのレイヤを指定するのかをあらかじめ設定しておく。あるいは、この設定をユーザが任意に行うことができるようにしてもよい。または、ズーミングされた結果としてディスプレイ１４の画面上に地図のどの範囲が表示されているかに応じて、指定するレイヤを切り替えるようにしてもよい。 When the number of zooming levels is larger than the number of layers, for example, which layer is designated for which level of zooming is set in advance. Alternatively, this setting may be arbitrarily performed by the user. Alternatively, the designated layer may be switched depending on which range of the map is displayed on the screen of the display 14 as a result of zooming.
　地図の表示範囲に応じてレイヤを指定する場合は、例えば次のようにすることが可能である。例えば、地図上に２以上の国の全域が表示される程度にズームアウトされているときは、図２（ａ）に示す国別レイヤを指定したものとする。また、地図上に２以上の都道府県の全域が表示される程度にズーミングされているときは、図２（ｂ）に示す都道府県別レイヤを指定したものとする。また、地図上に２以上の市区町村の全域が表示される程度にズーミングされているときは、図２（ｃ）に示す市区町村別レイヤを指定したものとする。さらに、地図上に１つの市区町村の全域が表示される程度にズーミングされているときは、図２（ｄ）に示す店舗別レイヤを指定したものとする。 When specifying a layer according to the display range of the map, for example, it is possible to do as follows. For example, when zoomed out to the extent that the entire region of two or more countries is displayed on the map, it is assumed that the country-specific layer shown in FIG. Further, when zooming is performed so that the entire region of two or more prefectures is displayed on the map, it is assumed that the prefecture-specific layer shown in FIG. 2B is designated. Further, when zooming is performed so that the entire area of two or more municipalities is displayed on the map, it is assumed that the municipality layer shown in FIG. 2C is designated. Furthermore, when zooming is performed so that the entire area of one city is displayed on the map, the store-specific layer shown in FIG. 2D is designated.
　スクロール操作受付部２は、ディスプレイ１４に表示される地図に対するユーザによるスクロール操作（上下左右の何れかへ表示領域を移動させる操作）を受け付ける。スクロール部４は、スクロール操作受付部２により受け付けられたユーザ操作に応じて、可視化処理部７を通じてディスプレイ１４に表示中の地図に対してスクロールの処理を行う。なお、スクロール操作受付部２は、本発明のエリア指定受付部に相当するものである。すなわち、スクロール操作受付部２は、地図に対するスクロール操作を通じて、後述する可視化処理部７による数値計算の対象とする地図上の所望のエリアの指定を受け付ける。 The scroll operation accepting unit 2 accepts a scroll operation (an operation to move the display area up, down, left, or right) by the user on the map displayed on the display 14. The scroll unit 4 performs a scroll process on the map being displayed on the display 14 through the visualization processing unit 7 in accordance with the user operation received by the scroll operation receiving unit 2. The scroll operation receiving unit 2 corresponds to the area designation receiving unit of the present invention. That is, the scroll operation accepting unit 2 accepts designation of a desired area on the map to be subjected to numerical calculation by the visualization processing unit 7 described later through a scroll operation on the map.
　例えば、関東地方の地図をディスプレイ１４に表示させている場合、可視化処理部７による数値計算の対象とする地図上のエリアは関東地方である。具体的には、関東地方の都道府県のうち、例えば全域が表示されている都道府県の範囲が数値計算の対象とする地図上のエリアである。これに対して、地図をスクロールさせて表示領域を変えた場合、スクロール後の画面上で全域が表示されている都道府県の範囲が、可視化処理部７による数値計算の対象とする地図上のエリアとなる。なお、ここでは、全域が表示されている都道府県のみを数値計算の対象に含めることとしたが、少なくとも一部が表示されている都道府県も数値計算の対象に含めるようにしてもよい。 For example, when a map of the Kanto region is displayed on the display 14, the area on the map that is subject to numerical calculation by the visualization processing unit 7 is the Kanto region. Specifically, of the prefectures in the Kanto region, for example, the range of the prefecture where the entire area is displayed is the area on the map that is the target of numerical calculation. On the other hand, when the map is scrolled and the display area is changed, the range of the prefecture where the entire area is displayed on the screen after scrolling is the area on the map that is subject to numerical calculation by the visualization processing unit 7 It becomes. Here, only the prefectures where the entire area is displayed are included in the numerical calculation target, but the prefectures where at least a part is displayed may also be included in the numerical calculation target.
　データ特定部５は、ズーム操作受付部１が受け付けたズーミングのユーザ操作により指定されたレイヤが持つレイヤ情報（図２参照）により示されている数値計算単位と、スクロール操作受付部２が受け付けたスクロールのユーザ操作により指定されたエリアとに基づいて、計算対象データ記憶部１３に記憶されている計算対象データの中から、数値計算の対象とするデータを特定する。上述のように、都道府県別レイヤに基づいて関東地方の地図がディスプレイ１４に表示されている場合、データ特定部５は、全域が表示されている都道府県を住所に持つデータを、可視化処理部７による数値計算の対象とするデータとして特定する。 The data specifying unit 5 receives the numerical calculation unit indicated by the layer information (see FIG. 2) of the layer specified by the zooming user operation received by the zoom operation receiving unit 1 and the scroll operation receiving unit 2 Based on the area designated by the scrolling user operation, data to be subjected to numerical calculation is specified from the calculation target data stored in the calculation target data storage unit 13. As described above, when a map of the Kanto region is displayed on the display 14 based on the prefecture-specific layer, the data specifying unit 5 uses the visualization processing unit for data having the address of the prefecture where the entire region is displayed. 7 is specified as data to be subjected to numerical calculation according to 7.
　例えば、地図上に東京都および埼玉県の全域が表示されていて、神奈川県、千葉県、茨城県、群馬県、栃木県、山梨県についてはそれぞれ一部のみが地図上に表示されている場合、データ特定部５は、図２（ｂ）に示す都道府県別レイヤのレイヤ情報により示されている数値計算単位（各都道府県）のうち、全域が表示されている東京都および埼玉県を住所に持つデータを、可視化処理部７による数値計算の対象とするデータとして特定する。 For example, the entire area of Tokyo and Saitama prefectures is displayed on the map, and only a part of Kanagawa, Chiba, Ibaraki, Gunma, Tochigi, and Yamanashi prefectures is displayed on the map. The data specifying unit 5 addresses the Tokyo and Saitama prefectures where the whole area is displayed among the numerical calculation units (prefectures) indicated by the layer information of the prefecture-specific layers shown in FIG. Are specified as data to be subjected to numerical calculation by the visualization processing unit 7.
　対象データ取得部６は、図３のように店舗名、店舗の住所、店舗での月別の売上数値を有して成る計算対象データをデータベースとして記憶した計算対象データ記憶部１３の中から、データ特定部５により特定されたデータを取得する。上述した例の場合、対象データ取得部６は、住所の欄に「東京都」または「埼玉県」のワードを含むレコードのデータを取得する。ここで取得するデータは、少なくとも売上数値に関するデータだけでよく、どのデータがどの都道府県のものかを区別できるようにしていれば、店舗名、住所のデータは必ずしも取得しなくてもよい。 As shown in FIG. 3, the target data acquisition unit 6 stores the calculation target data having the store name, the store address, and the monthly sales figures at the store as a database. Data specified by the specifying unit 5 is acquired. In the case of the example described above, the target data acquisition unit 6 acquires data of a record that includes the word “Tokyo” or “Saitama Prefecture” in the address column. The data acquired here is at least data related to sales figures, and store name and address data are not necessarily acquired as long as it is possible to distinguish which data belongs to which prefecture.
　可視化処理部７は、対象データ取得部６により取得されたデータに含まれる数値に対して数値計算単位毎に所定の計算を行い、その計算結果を地図上に可視化して表示させる。上述した例の場合、可視化処理部７は、対象データ取得部６により取得された東京都および埼玉県の売上数値に対して、東京都および埼玉県の単位で所定の計算を行い、その計算結果を地図上に可視化して表示させる。所定の計算は、例えばユーザが指定することが可能である。例えば、特定した年の年間総売上を集計するとか、特定した年の月刊売上平均値を集計するとか、数値計算の内容をユーザが任意に指定可能である。 The visualization processing unit 7 performs a predetermined calculation for each numerical calculation unit on the numerical value included in the data acquired by the target data acquisition unit 6, and visualizes and displays the calculation result on the map. In the case of the above-described example, the visualization processing unit 7 performs a predetermined calculation in units of Tokyo and Saitama Prefecture on the sales figures of Tokyo and Saitama Prefecture acquired by the target data acquisition unit 6, and the calculation result Is visualized and displayed on the map. The predetermined calculation can be designated by the user, for example. For example, the user can arbitrarily specify the contents of numerical calculation, such as summing up the total sales for the specified year, or summing up monthly sales average values for the specified year.
　図４は、可視化処理部７によって数値計算単位毎に行われる計算を説明するための図である。ここでは、特定した年の年間総売上を集計する例を示している。図４に示すように、ズーム操作受付部１が受け付けたズーム操作によって国別レイヤが指定されている場合、可視化処理部７は、全域を表示中の国に住所を有する各店舗の年間売上の合計値を国別に算出する。図４の例では、日本国内に住所を有する各店舗の年間売上の合計値“７５０”が算出されている。また、ズーム操作によって都道府県別レイヤが指定されている場合、可視化処理部７は、全域を表示中の都道府県に住所を有する各店舗の年間売上の合計値を都道府県別に算出する。図４の例では、東京都および埼玉県のそれぞれに住所を有する各店舗の年間売上の合計値“４５０”、“３００”がそれぞれ算出されている。 FIG. 4 is a diagram for explaining calculation performed by the visualization processing unit 7 for each numerical calculation unit. Here, an example is shown in which the total annual sales for the specified year are tabulated. As shown in FIG. 4, when the country layer is specified by the zoom operation received by the zoom operation reception unit 1, the visualization processing unit 7 displays the annual sales of each store having an address in the country where the entire area is displayed. Calculate the total value by country. In the example of FIG. 4, the total value “750” of annual sales of each store having an address in Japan is calculated. When the prefecture layer is designated by the zoom operation, the visualization processing unit 7 calculates the total value of the annual sales of each store having an address in the prefecture displaying the entire area, by prefecture. In the example of FIG. 4, total values “450” and “300” of the annual sales of each store having addresses in Tokyo and Saitama Prefecture are calculated.
　また、ズーム操作によって市区町村別レイヤが指定されている場合、可視化処理部７は、全域を表示中の市区町村に住所を有する各店舗の年間売上の合計値を市区町村別に算出する。また、ズーム操作によって店舗別レイヤが指定されている場合、可視化処理部７は、全域を表示中の特定の市区町村内に住所を有する各店舗の年間売上の合計値を店舗別に算出する。可視化処理部７は、以上のように指定レイヤに応じて数値計算単位別に算出された年間売上の合計値を、地図上の対応する数値計算単位のエリアまたは店舗に対応させて可視化して表示する。 In addition, when the municipality layer is specified by the zoom operation, the visualization processing unit 7 calculates the total value of the annual sales of each store having an address in the municipality that is displaying the entire area for each municipality. . When the store-specific layer is designated by the zoom operation, the visualization processing unit 7 calculates the total value of the annual sales of each store having an address in a specific city where the entire area is displayed for each store. The visualization processing unit 7 visualizes and displays the total value of annual sales calculated for each numerical calculation unit according to the designated layer as described above, corresponding to the area or store of the corresponding numerical calculation unit on the map. .
　計算結果を地図上に可視化する方法は、任意に設計することが可能である。例えば、数値計算単位毎に計算した年間売上の合計値を、当該数値計算単位を示す地図のエリア上にグラフや図形（例えば、棒グラフやバブルなど）として表示させる態様が可能である。図４の例で都道府県別レイヤが指定されている場合、図５に示すように、東京都に住所を持つ各店舗の年間売上の合計値を東京都の地図上にグラフまたは図形として表示させるとともに、埼玉県に住所を持つ各店舗の年間売上の合計値を埼玉県の地図上にグラフまたは図形として表示させる。グラフまたは図形と共に合計値を数値として表示してもよい。 The method for visualizing the calculation results on the map can be arbitrarily designed. For example, a mode is possible in which the total value of annual sales calculated for each numerical calculation unit is displayed as a graph or a graphic (for example, a bar graph or a bubble) on a map area indicating the numerical calculation unit. When the prefecture layer is specified in the example of FIG. 4, as shown in FIG. 5, the total value of the annual sales of each store having an address in Tokyo is displayed as a graph or figure on the map of Tokyo. At the same time, the total value of the annual sales of each store having an address in Saitama Prefecture is displayed as a graph or figure on the map of Saitama Prefecture. You may display a total value as a numerical value with a graph or a figure.
　別の表示態様として、図６に示すように、数値計算単位毎に計算された年間売上の合計値の大きさに応じて、当該数値計算単位を示す地図のエリアの表示色を変えることにより、数値計算単位毎に計算された数値の大きさに応じて分布図のように色分けした地図を表示させるようにしてもよい。 As another display mode, as shown in FIG. 6, by changing the display color of the area of the map showing the numerical calculation unit according to the size of the total value of the annual sales calculated for each numerical calculation unit, You may make it display the map classified by color like a distribution map according to the magnitude | size of the numerical value calculated for every numerical calculation unit.
　店舗別レイヤにおいて計算結果を地図上に可視化する場合は、例えば、図７（ａ）に示すように、各店舗の住所に該当する地図上の位置に、店舗が存在することを示す店舗アイコン７１を表示させる。そして、その店舗アイコン７１の近傍に、店舗毎に数値計算した結果をグラフや図形７２として表示させる。店舗アイコン７１自体の表示色、表示サイズまたは表示形状を、数値計算の結果に応じて可変とするようにしてもよい。 When the calculation result is visualized on the map in the store-specific layer, for example, as shown in FIG. 7A, a store icon 71 indicating that a store exists at a position on the map corresponding to the address of each store. Is displayed. Then, the result of numerical calculation for each store is displayed as a graph or a figure 72 in the vicinity of the store icon 71. The display color, display size, or display shape of the store icon 71 itself may be variable according to the result of numerical calculation.
　また、ズームイン操作によって地図上に１店舗のみが表示されるところまで拡大表示した場合、可視化の態様を変えるようにしてもよい。例えば、図７（ｂ）に示すように、その店舗の年間売上の合計値を数値７３として表示するとともに、その年の月別売上の推移をグラフ７４（折れ線グラフやパイチャートなど）の形式で表示したりするようにしてもよい。あるいは、種々の集計を行うことや、種々のパターンのチャートで表示することを指示するためのボタン７５を画面上に表示させ、ユーザ操作に応じて任意の集計を行い、その結果を任意のチャートとして表示できるようにしてもよい。 Further, when the zoom-in operation is performed to enlarge the display to the point where only one store is displayed on the map, the visualization mode may be changed. For example, as shown in FIG. 7B, the total value of the annual sales of the store is displayed as a numerical value 73, and the monthly sales transition of the year is displayed in the form of a graph 74 (line graph, pie chart, etc.). You may make it. Alternatively, buttons 75 for instructing to perform various tabulations and display in charts of various patterns are displayed on the screen, and arbitrary tabulations are performed according to user operations, and the results are displayed in any chart. May be displayed.
　以上詳しく説明したように、本実施形態では、地図上の地理的領域に基づく数値計算単位を示したレイヤ（国別レイヤ、都道府県別レイヤ、市区町村別レイヤなど）と、地理的領域以外の要素である施設に基づく数値計算単位を示したレイヤ（店舗別レイヤ）とを用意し、地図のズーム操作に応じて何れか所望のレイヤを指定することができるようにしている。そして、計算対象データ記憶部１３に記憶された計算対象データのデータベースの中から、指定されたレイヤにより示されている数値計算単位に基づいて特定されるデータを取得して所定の数値計算を行い、その計算結果を地図上に可視化して表示させるようにしている。 As described above in detail, in this embodiment, a layer indicating a numerical calculation unit based on a geographical area on a map (a layer by country, a layer by prefecture, a layer by city, etc.) and a region other than the geographical area A layer (store-specific layer) indicating a numerical calculation unit based on the facility which is an element of the above is prepared, and any desired layer can be designated according to the zoom operation of the map. And the data specified based on the numerical calculation unit shown by the designated layer is acquired from the database of the calculation target data stored in the calculation target data storage unit 13, and predetermined numerical calculation is performed. The calculation result is visualized and displayed on a map.
　このように構成した本実施形態によれば、ユーザが所望のレイヤを指定するためのズーム操作をするだけで、その指定されたレイヤが持つレイヤ情報に従って特定される地理的領域または施設を単位として数値計算が行われ、その数値計算の結果が地図上に可視化して表示されることとなる。すなわち、数値計算結果の可視化表示に関するドリルダウンおよびドリルアップを簡単なズーム操作だけで行うことができる。 According to this embodiment configured as described above, a user can perform a zoom operation for designating a desired layer, and a geographical area or facility specified according to the layer information of the designated layer can be used as a unit. Numerical calculation is performed, and the result of the numerical calculation is visualized and displayed on the map. That is, drill-down and drill-up related to the visualization display of numerical calculation results can be performed with a simple zoom operation.
　しかも、本実施形態では、単に地図上の地理的領域を拡縮して数値計算単位を変えるドリリングができるだけでなく、地理的要素以外の施設を数値計算単位として指定するためのドリリングも同じズーム操作で簡単に行うことができる。また、ズーム操作により指定したレイヤにおいて、簡単なスクロール操作だけで、可視化の対象とする数値計算範囲を変えることができる。これにより、本実施形態によれば、ユーザが面倒な入力操作を行うことなく、地理的領域およびそれ以外の施設といった要素を単位として数値計算した結果を地図上に簡単に可視化することができる。 Moreover, in this embodiment, not only can drilling be performed by simply changing the geographical area on the map to change the numerical calculation unit, but also drilling for designating facilities other than the geographical element as the numerical calculation unit can be performed by the same zoom operation. It can be done easily. In addition, in the layer designated by the zoom operation, the numerical calculation range to be visualized can be changed by only a simple scroll operation. Thereby, according to this embodiment, the result of numerical calculation can be easily visualized on a map without using a complicated input operation by the user as a unit of elements such as a geographical area and other facilities.
　なお、上記実施形態では、図２に示したように、実際に国名、都道府県名、市区町村名および店舗名を記憶させて各レイヤのレイヤ情報を設定しているが、レイヤ情報の構成はこれに限定されない。例えば、図８に示すように、数値計算単位を示すレイヤの項目名のみによってレイヤ情報を設定するようにしてもよい。この場合に設定する項目名は、計算対象データ記憶部１３に記憶されている計算対象データのデータベースに設定されている項目名と一致させる。 In the above embodiment, as shown in FIG. 2, the layer name of each layer is set by actually storing the country name, prefecture name, city name, and store name. Is not limited to this. For example, as shown in FIG. 8, the layer information may be set only by the item name of the layer indicating the numerical calculation unit. The item name set in this case is matched with the item name set in the calculation target data database stored in the calculation target data storage unit 13.
　すなわち、図８のようにレイヤ情報を構成する場合、計算対象データ記憶部１３に記憶する計算対象データのデータベースは、例えば図９のように構成する。図９の例では、データベースが店舗名および月別の売上を項目として有する点は図３と同様であるが、住所の項目が図３と異なっている。すなわち、図９の例では、住所の項目に代えて、国、都道府県および市区町村の３つの項目を有している。 That is, when configuring the layer information as shown in FIG. 8, the database of calculation target data stored in the calculation target data storage unit 13 is configured as shown in FIG. 9, for example. In the example of FIG. 9, the point that the database has the store name and monthly sales as items is the same as in FIG. 3, but the address item is different from FIG. That is, the example of FIG. 9 has three items of country, prefecture, and city instead of the address item.
　この場合、データ特定部５は、ズーム操作受付部１が受け付けたズーミングのユーザ操作に応じて、どのレイヤが指定されたかを特定する。また、スクロール操作受付部２が受け付けたスクロールのユーザ操作に応じて、地図上のどのエリアが指定されたかを特定する。そして、計算対象データ記憶部１３に記憶されている計算対象データの中から、指定されたレイヤのレイヤ情報（図８参照）と同じ名称の項目（例えば、都道府県の項目）において、指定されたエリアの名称と同じ名称（例えば、東京都および埼玉県の名称）が格納されたレコードのデータを数値計算の対象データとして特定する。 In this case, the data specifying unit 5 specifies which layer is designated in accordance with the zooming user operation received by the zoom operation receiving unit 1. In addition, it specifies which area on the map is designated according to the scroll user operation received by the scroll operation receiving unit 2. Then, the calculation target data stored in the calculation target data storage unit 13 is specified in the item having the same name as the layer information of the specified layer (see FIG. 8) (for example, the item of the prefecture). Data of a record in which the same name as the name of the area (for example, names of Tokyo and Saitama Prefectures) is stored is specified as target data for numerical calculation.
　また、上記実施形態では、施設の例としてチェーン店の各店舗を挙げて説明したが、施設は店舗に限定されるものではない。例えば、企業であってもよいし、公共施設であってもよい。また、上記実施形態では、施設が存在する位置を住所で表す例について説明したが、本発明はこれに限定されない。例えば、緯度経度により施設の位置を表すようにしてもよい。また、上記実施形態では、施設に関する数値として売上を挙げて説明したが、数値はこれに限定されない。 In the above embodiment, each chain store has been described as an example of a facility, but the facility is not limited to a store. For example, it may be a company or a public facility. Moreover, although the said embodiment demonstrated the example which represents the position where a facility exists with an address, this invention is not limited to this. For example, the location of the facility may be represented by latitude and longitude. In the above-described embodiment, sales have been described as numerical values related to the facility, but the numerical values are not limited thereto.
　また、可視化処理部７による数値計算および可視化の内容も、一定期間内における合計値や平均値を算出する数値計算や、グラフや図形の表示または分布図の表示による可視化に限定されるものではない。数値計算および可視化の内容は、計算対象データ記憶部１３に記憶される計算対象データの種類に応じて適宜変えることが可能である。例えば、図１０のように、製品毎の物流量を表すデータが計算対象データ記憶部１３に記憶されている場合、図１１に示すように、出発地から到着地までを結ぶ矢印の太さによって、物流量の大きさに関する集計結果を可視化するようにすることが可能である。 The contents of the numerical calculation and visualization by the visualization processing unit 7 are not limited to the numerical calculation for calculating the total value or the average value within a certain period, or the visualization by displaying a graph, a graphic, or a distribution diagram. . The contents of the numerical calculation and visualization can be appropriately changed according to the type of calculation target data stored in the calculation target data storage unit 13. For example, as shown in FIG. 10, when data representing the flow rate of each product is stored in the calculation target data storage unit 13, as shown in FIG. 11, depending on the thickness of the arrow connecting from the departure place to the arrival place. In addition, it is possible to visualize the result of counting related to the magnitude of the material flow rate.
　また、上記実施形態では、地理的領域に基づく数値計算単位を示したレイヤがあらかじめ設定されている例について説明したが、ユーザが任意に設定できるようにしてもよい。例えば、所望の都道府県を複数選択して所望の名称を付けることにより、所望のエリアを数値計算単位とするレイヤを任意に設定できるようにする。 In the above embodiment, the example in which the layer indicating the numerical calculation unit based on the geographical area is set in advance has been described. However, the user may arbitrarily set the layer. For example, a desired area can be arbitrarily set by selecting a plurality of desired prefectures and assigning a desired name.
　その他、上記実施形態は、何れも本発明を実施するにあたっての具体化の一例を示したものに過ぎず、これによって本発明の技術的範囲が限定的に解釈されてはならないものである。すなわち、本発明はその要旨、またはその主要な特徴から逸脱することなく、様々な形で実施することができる。 In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
