In this embodiment, the processing management data storage unit 54 stores, for example, the processing data shown in FIG. 5 and the order data shown in FIG. 6.

The processing data is, for example, data indicating how to perform the process of specifying a position on the map. The processing data includes, for example, a processing number, source material data, hit condition data, location coordinate type data, lot number search flag, residence display search flag, and second best point rank data.

The processing number is, for example, identification information of processing data.

The original document data is, for example, data indicating reference data used for position identification processing. Here, the original document data may indicate the name of reference data used in the location identification process.

The hit condition data is, for example, data indicating conditions used to specify a position.

The position coordinate type data indicates, for example, whether to specify the position of the contained point (for example, a representative point such as the center of gravity) of the polygon shown in the reference data, or the position of the point shown in the reference data. It is data.

The lot number search flag is, for example, a flag indicating whether or not to perform processing corresponding to processing data including the lot number search flag in specifying a position using the lot number as a key. In specifying a position using a lot number as a key, there is a possibility that processing corresponding to processing data in which the value of the lot number search flag is "1" will be executed. Further, in specifying a position using a lot number as a key, processing corresponding to processing data in which the value of the lot number search flag is "0" is not executed.

Further, the position on the map specified by the lot number corresponding position specifying process will be referred to as the lot number corresponding position, and the position on the map specified by the house display corresponding position specifying process will be called the house display corresponding position.

Further, reference data in which a lot number and a position on a map are associated with each other, which is referred to in the lot number corresponding position specifying process, will be referred to as lot number reference data. Further, reference data in which a residence display number and a position on a map are associated with each other, which is referred to in the residence display corresponding position specifying process, will be referred to as residence display reference data.

In this embodiment, as shown in FIG. 5, the brush polygon data, house-shaped polygon data, street polygon data, and government building polygon data correspond to lot number reference data. Further, in this embodiment, the house shape polygon data, house display point data, street polygon data, and government building polygon data correspond to house display reference data. In this way, in the lot number corresponding position specifying process, the brush polygon data is referred to, but the residence display point data is not referred to. Furthermore, in the residence display corresponding position specifying process, residence display point data is referred to, but brush polygon data is not referred to.

The second-best rank data is, for example, data representing the degree to which a specified position is the best. In the example of FIG. 5, the higher the degree to which it is best to specify a position by the process corresponding to the process data, the smaller the value of the second best point rank data included in the process data.

The order data is, for example, data indicating the execution order of the process indicated by the process data. As shown in FIG. 6, the order data includes a process number and a sequence number. In the present embodiment, for example, in specifying a position on a map corresponding to a search condition character string, processes are executed in order starting from the process corresponding to the process number associated with the smallest sequence number. Here, as described above, in the lot number corresponding position specifying process, the process corresponding to the processing data in which the value of the lot number search flag is "0" is skipped. In addition, in the residence display corresponding position specifying process, the process corresponding to the processing data in which the value of the residence display search flag is "0" is skipped.

In this embodiment, the site lot number management data storage unit 56 stores site lot number management data in which, for example, a V1 code, a house number, and a lot number are associated with each other. In the site lot number management data, a house number is associated with the lot number of the land on which the house corresponding to the house number is located.

In this embodiment, the receiving unit 58 receives, for example, a search condition string indicating an address notation. Here, the receiving unit 58 may also receive attribute information indicating the type of address notation indicated by the search condition character string.

In the present embodiment, the V1 code specifying unit 60 specifies, for example, a V1 code associated with a location indicated by a part of the search condition string, based on the search condition string received by the receiving unit 58. Here, for example, by referring to the V1 code management data stored in the V1 code management data storage unit 42, the V1 code included in the V1 code management data whose location partially matches the search condition string is shown. be identified.

The V1 code specifying unit 60 may specify NULL as the value of the V1 code when the V1 code management data whose location partially matches the search condition character string is not specified. In addition, when specifying the V1 code, differences between Chinese numerals and Arabic numerals, variations in the spelling of "ke", "ga", "ga", variations in the spelling of "tsu" and "tsu", etc. will be ignored. It's okay.

Here, the V1 code specifying unit 60 may further specify the location indicated in the specified V1 code management data. Then, the V1 code identification unit 60 may identify a character string obtained by removing the portion indicating the location from the search condition character string.

Hereinafter, the portion of the search condition string in which the location is indicated will be referred to as the location string, and the portion of the search condition string excluding the portion indicating the location will be referred to as the section string.

Here, the V1 code identification unit 60 performs various operations such as replacing full-width alphanumeric characters with half-width alphanumeric characters, replacing characters such as "number", "number", and "address" with hyphens regarding the block character string. You may also perform normalization processing on the search condition string. Here, the characters constituting the lot number, such as kanji such as "Koitsuhei" and kana such as "Iroha", may remain in the parcel character string even after the normalization process is performed.

In this embodiment, the address notation type identifying unit 62 specifies, for example, the type of address notation indicated by the search condition character string. Here, for example, the address notation type specifying unit 62 may specify the type of address notation indicated by the search condition character string based on the attribute information received by the receiving unit 58.

In this embodiment, the address notation type estimation unit 64 estimates the type of address notation indicated by the search condition string, for example, based on the search condition string. For example, if the address notation type identifying unit 62 does not specify the type of address notation indicated by the search condition string, the address indicated by the search condition string is determined based on the main number of the address notation indicated by the search condition string. The type of notation may be estimated. For example, the type of address notation indicated by the search condition string may be estimated when "unknown" is specified as the address notation type attribute or when the address notation type attribute is not specified.

Further, in this embodiment, the address notation type estimation unit 64 may estimate the type of address notation indicated by the search condition string, based on the main number of the address notation indicated by the search condition string. Here, the main number in the address notation in this embodiment refers to the part to the left of the leftmost hyphen in the block character string.

Further, when a division character string includes one hyphen, the part to the right of the hyphen is called a branch number. Furthermore, when the partition character string includes two hyphens, the part between the two hyphens is called a branch number. When the division character string includes two hyphens, the part to the right of the rightmost hyphen in the division character string is called the grandchild number.

For example, if the block string that is part of the search condition string is "1234-5," the main number of the address indicated by the search condition string is "1234." The branch number of the address notation indicated by the search condition character string is "5".

Further, for example, if the block character string that is part of the search condition character string is "105-1-1", the master number of the address indicated by the search condition character string is "105". The branch number of the address notation indicated by the search condition character string is "1". The grandchild number of the address notation indicated by the search condition character string is "1".

Further, for example, if the block character string that is part of the search condition character string is "3-7-1", the main number of the address notation indicated by the search condition character string is "3". The branch number of the address notation indicated by the search condition character string is "7". The grandchild number of the address notation indicated by the search condition character string is "1".

Further, for example, if the section character string that is part of the search condition string is "A71-3", the main number of the address indicated by the search condition character string is "A71". The branch number of the address notation indicated by the search condition character string is "3".

Further, for example, if the section character string that is part of the search condition character string is "I12-5", the master number of the address indicated by the search condition character string is "I12". The branch number of the address notation indicated by the search condition character string is "5".

A specific example of estimating the type of address notation indicated by the search condition string will be described later.

In this embodiment, the position specifying unit 66 determines search condition characters based on the type of address notation specified by the address notation type identifying unit 62 or the type of address notation estimated by the address notation type estimating unit 64, for example. Identify the location on the map that corresponds to the house designation shown in the column. Here, by referring to the reference data in which the specified type or estimated type of address notation is associated with the location on the map, the map corresponding to the address notation indicated by the search condition string is may be located. Here, as the position on the map, for example, latitude and longitude may be specified.

In the position specifying process by the position specifying unit 66, the processes represented by the process data including process numbers associated with the sequence numbers shown in FIG. 6 are executed in descending order of sequence numbers included in the sequence data. Ru. Here, as described above, in the lot number corresponding position specifying process, the process represented by the processing data in which the value of the lot number search flag is set to 0 is skipped. Furthermore, in the residence display corresponding position specifying process, the process represented by the process data in which the value of the address display search flag is set to 0 is skipped.

In the position specifying process performed by the position specifying unit 66, the reference data whose name is indicated by the original document data included in the process data is specified, which satisfies the condition indicated by the hit condition data included in the process data.

When the hit condition data is "address complete match", reference data whose included lot number or house display number completely matches the search condition character string is specified. When the hit condition data is "complete match of main number", reference data in which the included lot number or residence display number matches in the description from the prefecture to the main number is identified. When the hit condition data is "location complete match", reference data whose included lot number or house display number matches in the location description is specified. When the hit condition data is "complete location match excluding small letters," reference data in which the contained lot number or house number indicates a match in the description of the location excluding small letters is identified. If the hit condition data is "prefecture, city, ward, town, village complete match," reference data whose included lot number or house display number matches in the description from the prefecture to the city, ward, town, or village is identified. If the hit condition data is "the closest parent number", the reference data whose included lot number or residence display number matches the description of the location and whose parent number is the closest is identified. If there is no reference data that satisfies the condition indicated by the hit condition data, the position specifying process is executed for the processing data corresponding to the next sequence number.

Then, when the reference data is specified, the position on the map is specified based on the specified reference data. If the value of the position coordinate type data included in the processing data corresponding to the process being executed here is "containing point", the polygon associated with the lot number or address display number in the specified reference data. The position of a representative point (eg, center of gravity) on the map is specified. In addition, if the value of the location coordinate type data included in the processing data corresponding to the process being executed is "point", a map of the point associated with the lot number or address display number in the specified reference data. The upper position is specified.

When a plurality of pieces of reference data are specified here, the position on the map associated with the lot number or address display number may be specified in any of the reference data. Alternatively, the location on the map of the representative point (for example, the center of gravity) of the location associated with the lot number or address display number for each of the identified plurality of reference data may be identified. Alternatively, the location on the map of the representative point (e.g., center of gravity) of a polygon (e.g., convex hull) that includes the polygon associated with the lot number or address display number for each of the specified plurality of reference data is specified. Good too. In addition, if data indicating a polygon that includes a polygon associated with a lot number or address display number for each of multiple pieces of data is stored as reference data, the location on the map of the representative point of the polygon is stored. may be specified.

Furthermore, in the present embodiment, in the position specifying process by the position specifying unit 66, the next best point rank included in the process data corresponding to the process executed when the position on the map was specified as well as the position on the map. The value of the data is determined.

For example, in the lot number corresponding position specifying process, first, the process corresponding to the process data whose process number is 1 is executed. In this process, brush polygon data is referred to. Then, in the brush polygon data, the position of the representative point of the polygon associated with the lot number indicated by the search condition character string is identified. If the position is specified through this process, 1 is specified as the value of the next best point rank data.

If the position is not specified by the process, the process corresponding to the process data with process number 2 is executed. In this process, brush polygon data is referred to. Then, in the brush polygon data, the position of a representative point of a polygon that is associated with a lot number whose description from the prefecture to the main number matches in the search condition character string is specified. If the position is specified through this process, 2 is specified as the value of the second-best rank data.

If the position is not specified by the process, the process corresponding to the process data with process number 3 is executed. In this process, house-shaped polygon data is referred to. Then, in the house-shaped polygon data, the position of the representative point of the polygon associated with the lot number indicated by the search condition character string is specified. If the position is specified through this process, 1 is specified as the value of the next best point rank data.

If the position is not specified by the process, the process corresponding to the process data with process number 4 is executed. In this process, house-shaped polygon data is referred to.

In this embodiment, the display control unit 68 causes the terminal 12 to display information indicating the position on the map specified by the position specifying unit 66, for example. Here, for example, the display control unit 68 may generate a map image 30 showing the position on the map specified by the position specifying unit 66. Then, the display control unit 68 may transmit the generated map image 30 to the terminal 12. The terminal 12 may then display the received map image 30 on the output unit 12d.

7A and 7B are flowcharts illustrating an example of the flow of the process of specifying the location on the map corresponding to the residence display indicated in the search condition character string, which is performed in the server 10 according to the present embodiment. This will be explained with reference to.

First, the receiving unit 58 receives a search condition string and attribute information from the terminal 12 (S101).

Then, the V1 code specifying unit 60 specifies the V1 code included in the V1 code management data whose location partially matches the search condition character string received in the process shown in S101 (S102). Here, the V1 code is specified by referring to the V1 code management data stored in the V1 code management data storage section 42. In the process shown in S102, the location character string and the partition character string are specified. In addition, the above-mentioned search condition string normalization process is also executed.

Then, the address notation type specifying unit 62 specifies the type of address notation based on the attribute information received in the process shown in S101 (S103).

Then, the address notation type identifying unit 62 determines whether the type of address notation specified by the user is unknown (S104). For example, if "unknown" is specified as the address notation type attribute, or if the address notation type attribute is not specified, the address notation type specified by the user will be determined to be unknown. You can also do this.

Assume that it is determined in the process shown in S104 that the type of address notation specified by the user is unknown (S104: Y). In this case, the address notation type estimating unit 64 estimates the type of address notation indicated by the search condition string that has undergone the normalization process (S105). Estimation of the type of address notation will be described later.

Then, the position specifying unit 66 confirms whether the type of address notation estimated in the process shown in S105 is an address display number (S106).

Assume that in the process shown in S106, it is confirmed that the type of address notation estimated in the process shown in S105 is an address display number (S106: Y). In this case, the position specifying unit 66 specifies both the lot number corresponding position and the house display corresponding position (S107) based on the search condition string that has been subjected to the normalization process, as shown in the present processing example. Processing is terminated. Here, both the above-described lot number corresponding position specifying process and the above-described house display corresponding position specifying process are executed.

Assume that it is determined in the process shown in S104 that the type of address notation specified by the user is not unknown (S104: N). In this case, the position specifying unit 66 checks whether the type of address notation specified in the process shown in S103 is a lot number (S108).

Suppose that it is confirmed in the process shown in S108 that the type of address notation specified in the process shown in S103 is not a lot number (S108: N). In this case, the position specifying unit 66 checks whether the type of address notation specified in the process shown in S103 is a house number (S109).

Assume that in the process shown in S109, it is confirmed that the type of address notation specified in the process shown in S103 is a house number (S109: Y). In this case, the position specifying unit 66 specifies the lot number corresponding to the house number indicated by the search condition string that has undergone the normalization process (S110). Here, the lot number management data is referred to, and in the lot number management data, the lot number that is associated with the house number indicated by the search condition string that has been normalized is identified.

Then, the position specifying unit 66 executes the above-described lot number corresponding position specifying process, specifies the lot number corresponding position corresponding to the lot number specified in the process shown in S110 (S111), and the process shown in this processing example ends. be done.

Assume that in the process shown in S106, it is confirmed that the type of address notation estimated in the process shown in S105 is not an address display number (S106: N). In this case as well, the position specifying unit 66 executes the above-described lot number corresponding position specifying process, specifies the lot number corresponding position based on the search condition string that has been normalized (S111), and this process example The process shown in is completed.

Suppose that it is confirmed in the process shown in S109 that the type of address notation specified in the process shown in S103 is not a house number (S109: N). In this case, the type of address notation specified in the process shown in S103 is a residence display number. In this case, the position specifying unit 66 executes the above-described house display corresponding position specifying process, specifies the house display corresponding position based on the search condition string that has been normalized (S112), and The processing shown in the processing example is ended.

In the processing shown in S111 and S112 in the above processing example, the position specifying unit 66 calculates the value of the next best point rank data included in the processing data corresponding to the process executed when the position on the map is specified. Also specified.

In the process shown in S110 of the above processing example, when the lot number associated with the house number indicated by the search condition string does not exist, the lot number associated with the house number indicated by the search condition string is may not be identified. In this case, in the process shown in S111, the position specifying unit 66 assumes that the house number indicated by the search condition string that has undergone the normalization process is a lot number, and executes the first lot number corresponding position specifying process. good. In this case, in the process shown in S111, the position specifying unit 66 also assumes that the description from the prefecture to the branch number of the house number indicated by the search condition string that has undergone the normalization process is a lot number. A second lot number corresponding position specifying process may be executed.

Then, among the positions specified in each of the first lot number corresponding position specifying process and the second lot number corresponding position specifying process, the one with the smaller value of the second best point rank data specified together with the position on the map is selected in step S111. It may be adopted as the location on the map specified in the process shown in FIG.

Next, an example of the flow of the address notation type estimation process shown in S105 will be described with reference to the flowchart illustrated in FIG. 8.

First, the address notation type estimating unit 64 checks whether the main number of the address notation indicated by the search condition string that has been normalized is 100 or more (S201).

Assume that it is confirmed in the process shown in S201 that the main number of the address notation indicated by the search condition string for which the normalization process has been performed is not 100 or more (S201: N). In this case, the address notation type estimating unit 64 checks whether the main number of the address notation indicated by the search condition string that has undergone the normalization process includes kanji or kana (S202). For example, when the main number of the address indicated by the search condition string that has undergone normalization processing includes kanji or kana, it means, for example, if the main number of the address indicated by the search condition string is "K71" or "I 12".

Assume that in the process shown in S202, it is confirmed that neither kanji nor kana is included in the main number of the address notation indicated by the search condition string that has undergone the normalization process (S202: N). In this case, the address notation type estimating unit 64 checks whether the value of the V1 code residence display flag corresponding to the search condition string subjected to the normalization process is "0" (S203). Here, for example, the value of the V1 code residence display flag included in the V1 code management data indicating a location that partially matches the search condition character string received in the process shown in S101 is checked.

Suppose that it is confirmed that the value of the V1 code residence display flag corresponding to the search condition string for which the normalization process has been performed is not "0" (that is, "1") (S203: N). In this case, the region to which the location corresponding to the search condition character string belongs is the residence display implementation region. Therefore, in this case, the address notation type estimating unit 64 estimates the type of address notation indicated by the search condition string subjected to the normalization process to be a residence display number (S204), and the process shown in S105 is ended.

Note that if the value of the V1 code specified in the process shown in S102 is NULL, the value of the V1 code residence display flag cannot be confirmed in the process shown in S203. In this case as well, the address notation type estimating unit 64 estimates the type of address notation indicated by the search condition string subjected to the normalization process to be a residence display number (S204), and the process shown in S105 is ended.

Assume that in the process shown in S201, it is confirmed that the main number of the address notation indicated by the search condition character string subjected to the normalization process is 100 or more (S201: Y). In this case, the address notation type estimating unit 64 estimates the type of address notation indicated by the search condition string subjected to the normalization process to be a lot number (S205), and the process shown in S105 is ended.

Assume that in the process shown in S202, it is confirmed that the main number of the address notation indicated by the search condition string for which the normalization process has been performed includes a kanji or a kana (S202: Y). In this case as well, the address notation type estimating unit 64 estimates the type of address notation indicated by the search condition string subjected to the normalization process to be a lot number (S205), and the process shown in S105 is ended.

Assume that in the process shown in S203, it is confirmed that the value of the V1 code residence display flag corresponding to the search condition string for which the normalization process has been performed is "0" (S203: Y). In this case, the area to which the location corresponding to the search condition character string belongs is not the housing display implementation area but the lot number area. Therefore, in this case as well, the address notation type estimating unit 64 estimates the type of address notation indicated by the search condition character string subjected to the normalization process to be a lot number (S205), and the process shown in S105 is ended.

For example, assume that the search condition string for which the normalization process has been performed is "5-1234-5 Minamiedo, Matsuyama City, Ehime Prefecture" and "lot number" is specified as the address notation type attribute. In this case, in the lot number corresponding position specifying process, the process corresponding to the processing data whose process number is 1 is executed, and the lot number corresponding position is specified. Further, 1 is specified as the value of the second best point rank data.

For example, assume that the search condition string for which the normalization process has been performed is "5-1234-5 Minamiedo, Matsuyama City, Ehime Prefecture" and the address notation type attribute is unknown. In this case, since the main number of the search condition string is 1234, the type of address notation is presumed to be a lot number. Then, in the lot number corresponding position specifying process, the process corresponding to the processing data whose process number is 1 is executed, and the lot number corresponding position is specified. Further, 1 is specified as the value of the second best point rank data.

For example, assume that the search condition string for which the normalization process has been performed is "4-3-7 Yamakoshi, Matsuyama City, Ehime Prefecture" and that "residential display number" is specified as the address notation type attribute. In this case, in the residence display corresponding position specifying process, the process corresponding to the process data whose process number is 3 is executed. Here, it is assumed that the residence display corresponding position could not be specified in the process. Then, the process corresponding to the process data whose process number is 4 is executed. Then, the residence display corresponding position is specified by the process corresponding to the process data with the process number 4. Further, 2 is specified as the value of the second best point rank data.

For example, assume that the search condition string for which the normalization process has been performed is "4-105-1-1 Yamakoshi, Matsuyama City, Ehime Prefecture," and the address notation type attribute is "house number." Assume that the lot number corresponding to the house number cannot be identified in the process shown in S110. In this case, the lot number corresponding position specifying process is executed using each of "4-105-1-1 Yamakoshi, Matsuyama City, Ehime Prefecture" and "4-105-1 Yamakoshi, Matsuyama City, Ehime Prefecture" as keys.

Here, it is assumed that in the lot number corresponding position specifying process for "4-105-1-1 Yamakoshi, Matsuyama City, Ehime Prefecture", the lot number corresponding position could not be specified in the process corresponding to the processing data with the process number 1. Assume that the location corresponding to the lot number can be specified by the process corresponding to the process data with the process number 2. In this case, 2 is also specified as the value of the next best point rank data.

On the other hand, it is assumed that in the lot number corresponding position specifying process for "4-105-1 Yamakoshi, Matsuyama City, Ehime Prefecture", the lot number corresponding position can be specified by the process corresponding to the processing data with the process number 1. In this case, 1 is also specified as the value of the next best point rank data.

From the above, the lot number corresponding position identified in the lot number corresponding position identification process for "4-105-1 Yamagoe, Matsuyama City, Ehime Prefecture", which has a small value of the next best point rank data identified together with the location on the map, is determined in S111. This will be adopted as the location specified in the process.

If the type of address notation is not specified, such as when the user does not know the type of address notation indicated by the search condition string, the reference data to be referred to in the location search cannot be specified, and as a result, It is not possible to accurately identify a location in the search results.

Based on this, in the present embodiment, as described above, the address notation type estimation unit 64 determines the type of address notation indicated by the search condition string based on the main number of the address notation indicated by the search condition string. Estimate. Then, by referring to the reference data in which the estimated type of address notation and the location on the map are associated, the location specifying unit 66 determines the location on the map corresponding to the address notation indicated by the search condition string. Identify.

In this way, according to the present embodiment, even if the type of address notation indicated by the search condition string is not specified, it is possible to accurately identify a position that is a search result of the search condition string.

Furthermore, if the main number of the address is 100 or more, or if the main number of the address includes kanji or kana, there is a high possibility that the area represented by the address is a lot number area. Based on this, in this embodiment, as described above, the address notation type estimation unit 64 determines whether the main number of the address notation indicated by the search condition string is 100 or more, or if the address notation type indicated by the search condition string is It is estimated whether the address notation indicated by the search condition character string is a lot number or a house display number based on whether the main number of the search condition includes kanji or kana. For example, either the main number of the address notation indicated by the search condition string is 100 or more, or the main number of the address notation indicated by the search condition string contains kanji or kana. If so, it is presumed that the address notation indicated by the search condition character string is a lot number (see S201, S202, and S206). In this way, it is possible to accurately estimate whether the type of address notation indicated by the search condition character string is a lot number or a house display number.

Furthermore, in this embodiment, it is conceivable that a lot number may be designated even in an area where address display is implemented. Based on this, in the present embodiment, if the search condition character string is estimated to indicate a house display number, the location specifying unit 66 performs a lot number corresponding position specifying process in addition to the house display corresponding position specifying process. It is further executed (see S106 and S107). Here, in the residence display corresponding position specifying process, a position corresponding to the address notation indicated by the search condition character string specified by referring to the residence indication reference data is specified. In the lot number position correspondence process, the location corresponding to the address notation indicated by the search condition character string is specified by referring to the lot number reference data.

In this case, a map image 30 may be displayed on the terminal 12 in which two markers 32 representing a location corresponding to a lot number and a location corresponding to a house display are placed, respectively.

Further, in this embodiment, when receiving a search condition string indicating a house number, the position specifying unit 66 specifies the lot number corresponding to the house number by referring to the lot number management data (see S110).

Here, as described above, when the lot number corresponding to the house number is specified, the location specifying unit 66 performs the lot number corresponding position identification including the process of specifying the position associated with the lot number in the lot number reference data. Processing may be executed.

Further, when the lot number corresponding to the house number is not specified, the location specifying unit 66 performs a process of specifying the position on the map that is associated with the lot number that matches the house number indicated by the search condition string in the lot number reference data. You may perform the lot number corresponding position identification process including. In this case, the location specifying unit 66 further specifies the location on the map that is associated with the lot number that matches the part from the prefecture to the branch number of the house number indicated by the search condition character string in the lot number reference data. You may perform the 2nd lot number corresponding position identification process which includes processing. In this case, a map image 30 on which two markers 32 each representing a specified position are arranged may be displayed on the terminal 12. Further, as described above, the map image 30 on which the two markers 32 representing the smaller value of the second best point rank data that is also specified among the two specified positions is arranged is displayed on the terminal 12. You can do it like this.

Note that the present invention is not limited to the above-described embodiments.

For example, when there is reference data in which a house number and a polygon are associated, a polygon corresponding to the house number indicated by the search condition character string may be specified in the reference data. Then, the position on the map of the representative point of the polygon may be specified.

Furthermore, for example, the division of roles between the server 10 and the terminal 12 is not limited to the above. For example, map data may be stored in the terminal 12. Then, the information on the position on the map and the value of the next best point rank data may be transmitted from the server 10 to the terminal 12. The terminal 12 may then generate the map image 30 based on the transmitted map position information and map data. Then, the terminal 12 may display the map image 30 on the output unit 12d.

Furthermore, the above-mentioned specific character strings and numerical values as well as the specific character strings in the drawings are merely examples, and the present invention is not limited to these character strings and numerical values.
