Recently, the Internet and geographical information systems have been combined with the Internet geographical information system, and the physical and social infrastructure for utilizing the geographical information system has been greatly improved.

At the same time, the geographical information system project at the national level and the urban planning information system data of each city are gradually getting rid of the supply shortage of spatial data.

In general, a geographic information system (GIS) is a system that manages spatial information that can be used in terrain and facility related fields by constructing and processing geospatial data.

In particular, roads and water and wastewater facility management systems that manage urban infrastructure are developed and operated as client / server (C / S) environments.

Here, the client / server environment refers to an environment in which a client application program installed in a user computer operates as a process of responding information corresponding to a request from the remote server to the remote server through the network.

In addition, the Urban Planning Information System (UPIS) refers to an information management system that is used in urban planning related urban planning tasks of local governments and supports various decisions related to urban planning.

Since the early 1990s, advanced cities have been steadily accumulating space DBs in preparation for changes in such urban planning environments.

In addition, as an information exchange tool in the urban policy and urban planning field by utilizing the urban planning information system, citizens are encouraged to use the urban planning information system as a support system to cooperate with the city government and city planner to promote urban planning, have.

In other words, in advanced countries, the unique potential of geographic information systems is blossoming in urban planning and urban policy, and urban planning information system is becoming the most important methodology for integrating and exchanging city information.

Finally, the central role of the urban planning information system in the local government is both a means of information exchange in the planning process using scientific spatial analysis and a means of supporting spatial planning.

Therefore, the vision and policy of a clear urban planning information system that is shared by citizens, governments, and corporations is needed, and the function as a cooperative planning system that can expand citizen participation in city planning process and present creative alternatives This trend is being emphasized recently.

Accordingly, DBs, which are related to urban planning according to the city management plan, can be searched according to the conditions of the city planning items desired by the users.

Here, the image drawing is an image file generated from an electronic file through a scanner using a paper drawing used at the time of notification, and in the conventional urban planning information system, an individual city planning document is checked in an image drawing and a drawing is selected one by one It is used as reference material for display and viewing.

However, this limited reference method has limitations in accurately confirming and using information that contains the terrain, intellectual, and urban planning information at the time of the examination.

Accordingly, the present inventor has proposed a method of mapping geographical information requested by a user terminal to geographical information from a city planning information system server, mapping the requested geographical map with an electronic map, , It has come to devise a geographical information inquiry method which can intuitively and accurately analyze urban planning information based on the topography and intellectual status at the time of the examination.

The operation of the geoinformation inquiry method through location matching and spatial search according to the present invention will be described with reference to FIGS. 1 to 6. FIG.

The electronic map constructed in the city planning is based on the shape-type data that can be provided through the electronic map providing unit 210 in the geographic information system by converting the spatial information of the urban plan set in the current city plan into a vector .

In order to provide the service by superimposing the electronic map and the image drawing, the image drawing management unit 220 manages the basic information of the image drawing and the electronic map mapping information.

A method of registering an image drawing in the image drawing management unit 220 is as follows.

The user moves the electronic map to the desired position in the display unit screen of the user terminal (S110), selects the image drawing stored in the user terminal (S120), and drags and drops the selected image drawing on the display unit (S130).

The display unit receives the drop event and transmits the image drawing selected by the user from the user terminal to the city planning information system server (S140).

The transmitted image drawing file further registers the thumbnail image according to the ratio of the designated size, so that the load on the display unit is minimized when the search result is slid.

At this time, a thumbnail image is generated based on the long axis ratio between the horizontal axis and the vertical axis of the image drawing.

Immediately after the image drawing is loaded on the display unit, the scale and the position coordinates of the electronic map are superimposed on each other in a state where they do not coincide with each other, so a predetermined position mapping operation must be performed.

That is, the city planning information system server reads the image drawing file transmitted by the user, and performs the following primary location mapping in order to superimpose the image drawing together with the electronic map on the display unit (S150).

First, the location mapping controller 230 in the city planning information system server adjusts the position of the image drawing and moves the center of the image drawing so that the center of the image drawing coincides with the position of the electronic map, thereby adjusting the center position (S151).

At this time, the opacity value is adjusted using the transparency setting function of the image drawing so that the lot number of the electronic map can be displayed (S152).

In the image drawing, there are additional areas such as a legend and a title, which are areas other than the part where the urban plan drawing is drawn. This area is an unnecessary area when mapping with the electronic map. Therefore, only the map area of the image drawing A rectangular box is selected to cut the image (S153).

At this time, the cut target is an image temporarily displayed on the display unit, not the original image drawing itself, and the map area selection box designated by the image drawing management unit 220 is designated as an image drawing map box and managed (S154).

Next, the following secondary position mapping is performed for position correction through distortion control of the image drawing (S160).

Adjust the positions of the four corner vertices of the image drawing map box and the contour transformation points at the center of the four sides to match the position of the electronic map as much as possible.

It is possible to distort the image drawing by trapezoid, rhombus, and parallelogram shape of rectangle image drawing by moving corner vertices, and by moving contour line deformation point to increase precision, distortion of image drawing is set so as to match with electronic map as much as possible.

When the secondary position mapping operation between the image drawing and the electronic map is completed, the metadata unit 240 registers the image drawing basic information and the additional information together to generate image drawing metadata (S170).

As shown in FIG. 5, the metadata includes a city planning record classification (roads, parking lots, residential areas for exclusive use of the first class, planning management areas, etc.) included in a notice number (notice agency, notice year, serial number) ) List, an extent of the image drawing, four corner vertex coordinates of the image drawing map box, distortion corner coordinates, projection information, image actual horizontal size, resolution, and image drawing storage path.

The image drawing management unit 220 matches all the registered image drawings with the metadata items on a one-to-one basis (S180).

A method of searching for and superimposing the electronic map and the position-mapped image drawing on the electronic map through the above process (S190) is as follows.

If a predetermined point is selected (S192) by moving to a position required in the electronic map (S191) by clicking a space search button, the spatial information searching unit 250 receives the coordinates of the selected point, The vertex range information is firstly searched in space (S193).

The distorted vertex coordinate list is compared with the metadata of the target image drawing including the distorted vertex including the coordinates of the selected point (S194), and the image drawing including the selected point is searched in the second space (S195).

The reason why the image drawing is searched for the second time is that if the number of the image drawing increases, it takes a lot of resources and time to compare all the distorted vertices. Therefore, the space search is first performed based on the four corner points of the map box This is to ensure a fast spatial search by making the objects smaller and comparing them.

The spatial search result of the image drawing superimposed on the point designated by the user is sorted in the order of the notified numbers using thumbnails generated when the image drawing is transmitted (S196) and displayed as an image list on the image slide bar (S197).

When the thumbnail image is selected and clicked (S198), the image map is superimposed on the electronic map on the basis of the positional information correction values set in the mapping with the electronic map (S199).

On the other hand, when a mouse-over event occurs in the thumbnail, notice basic information (notice number, notification title, city planning record classification list, etc.) of the image drawing metadata is displayed on the display unit.

In addition, a plurality of image drawings can be superimposed on the map, and when the map is enlarged, reduced, or moved, the image drawing changes in the same manner.

Through this process, it is possible to analyze the urban planning information based on the topographical and intellectual status at the time of the examination without being affected by the changes in the current environment by superimposing the image drawings on the electronic map. It will be able to compare and analyze at that time.

As described above, the geoinformation inquiry method through location matching and spatial search of the present invention is a method of locating geographical information from a city planning information system server, mapping image maps requested with a user terminal to an electronic map, It is possible to intuitively analyze urban planning information based on topographical and intellectual status at the time of notification, without being affected by changes in the current environment by superimposing the image drawings on the electronic map by searching the additional metadata by spatial search.

Through this, it is possible to analyze the geographic information intuitively and accurately by comparing the present and the present time without being affected by the change in the present environment even if the person in charge of the city planning is changed.

In addition, since the search is performed using the thumbnail image of the requested image drawing, the load on the display unit during the slide can be minimized, and even when the number of image drawings to be displayed increases, the size of the image to be searched is reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes, modifications, substitutions, and equivalents may be made therein without departing from the spirit and scope of the invention.
