The map information providing method according to an embodiment of the present invention is executed in the service server 1000 that is linked with the user client 2000 and the network 10. [

The service server 1000 of the present embodiment can be understood as a web server or an app server that provides a blog, a social networking service (SNS), or the like in response to a request from the user client 2000. Blogs, social networking services (SNS), etc., for example, posting contents informing around individual leisure activities such as a visit to a restaurant, a travel destination, and the like, including geotagged images such as a landscape photograph and a building photograph Can be.

2, the service server 1000 includes an operation module 110 for operating a general server environment, a user module 110 for receiving a web service or an application service request of a user client and providing a processing result A client interworking module 102, a geographical information processing module 104 for acquiring and acquiring geographical information about specific coordinates (geographical coordinates) in a geographical information DB provided in the geographical information data server or included in the geographical information data server, And a map information processing module 106 for generating a map image based on the map information.

The map information processing module 106 can be understood as a general GIS (Geographic Information System) engine that generates and provides various geographical information displays including maps based on the geographical information data.

For example, the map information processing module 106 may provide functions such as background map application, position visualization, map scale adjustment (automatic / manual), map image rendering, and map image file creation using the geographical information data . Background map application is to generate background map using map data, and position visualization is to map coordinate information and background map.

The service server 1000 of the present embodiment includes a service provision information DB 120 for managing service details requested and processed by a user and a geographical information DB 130 for managing geographical information data on the geographical and geographical space .

As in the embodiment of FIG. 2, the service server 1000 may include a geographical information DB 130 itself in order to obtain geographical information data. Alternatively, the service server 1000 may be linked with the geographical information data server 3000 operated through a network. In this case, the geographical information data server 3000 may be provided with a geographical information DB (not shown) have.

The user client 2000 of the present embodiment can be understood as a mobile or desktop type client that displays a blog, a social networking service (SNS), and the like to a user in cooperation with the service server 1000.

3, the user client 2000 includes an operation module 210 for operating a general client environment, a service server interworking module 202 for interworking with a service server and performing data request and reception processing ), And a service processing module 204 for displaying a web service or an app service such as a blog including an image, a social networking service (SNS) or the like, using data provided by the service server.

The user client 2000 executes map image control processing (e.g., enlargement / reduction / transformation / additional information display) in association with the map image provided by the service server 1000, and renders and provides a map based on the geographical information data And a map information processing module 210 for the map information.

The geographical information data server 3000 can be understood as a normal GIS server having a geographical information DB.

4 is a flowchart of a map information providing method according to an embodiment of the present invention.

The present embodiment can be understood as a case where the service server 1000 has the function of the geographical information data server and both the geographical information DB and the map information processing module are provided in the service server 1000.

In step S1, the service server 1000 receives geotagging information from the user client 2000. The geotagging information is based on a user's selection command (e.g., click and touch input) with respect to the geotagged image (e.g., landscape photograph) displayed on the screen of the user client 2000 And transmitted to the service server 1000.

Preferably, image size information is further received from the user client 2000 in step S1. For example, the geotagging information is geotagged on the blog of the user client 2000 or on the image displayed on the SNS service screen, and the image size information may be displayed on the screen of the user client 2000 (e.g., blog screen, SNS screen) The size information of the image (for example, a landscape photograph) displayed on the screen.

In step S2, the service server 1000 obtains coordinate information for generating map information from the geotagging information. The coordinate information can be understood as ordinary geographical coordinates.

In step S3, the service server 1000 generates a map image file of the area including the coordinates by using the coordinate information and the geographic information data.

The geographical information data may be normal vector data that can be used for generating a map image, or may be data for generating other types of maps such as raster data.

The generation of the map image file can be understood to image the map image rendered with a specific scale based on the coordinate information. For example, the map image file may be a normal PNG, JPG, GIF, BMP file, or the like.

If the image size information is further transmitted from the user client 2000 in step S1, the image size of the map image file is determined based on the image size information in step S3.

For example, if the size of the image received from the user client 2000 in step S1 is 300 * 300, the image size of the map image file in step S3 is 250 * 250-350 The image size of the blog image may be determined as a predetermined image size similar to the size of the blog photo image.

For example, the size of the map image file may be determined by applying a predetermined enlargement ratio (for example, 120%) to the image size received from the user client 2000 or applying a predetermined reduction ratio (for example, 80% , Or may be determined at the same rate (100%). As another example, the size of the map image file may be determined by using at least one of the image size and the screen resolution information from the user client 2000 using the image size received from the user client 2000, And may be determined by applying an enlargement or reduction ratio. For example, when the screen size of the user client 2000 is equal to or larger than the reference size preset in the service server 1000, the map image file is enlarged at a preset ratio, 1000), the map image file can be reduced by a preset ratio. When the screen resolution of the user client 2000 is equal to or larger than the reference resolution set in advance in the service server 1000, the map image file is enlarged at a preset ratio, When the server 1000 is less than the preset reference resolution, the map image file can be reduced to a preset ratio. You can zoom in and out the map image file size by linking the screen size and resolution together. The user client 2000 may be further provided with a function of transmitting the screen size and / or screen resolution information to the service server 1000.

Preferably, the scale of the map constituting the map image file is set based on the coordinate information in step S3. The scale setting or adjustment may be made automatically based on a predetermined rule.

For example, different scales are set when the coordinate information is the domestic coordinate information and when the coordinate information is the international coordinate information. For example, the scale of the map is adjusted so that a range of 2 km in the case of the domestic coordinate information and 200 km in the case of the overseas coordinate information is included in the map image. In Korea, detailed map is needed. In case of overseas, it is necessary to inform the location of each country so that users can easily use the map image. These scale setting rules may be determined separately for each region and each country. 8 is an exemplary screen for adjusting the scale of a map image in the domestic and foreign countries according to an embodiment of the present invention.

As another example, the determination of the scale of the map image file may be determined by receiving at least one of the screen size and the screen resolution information from the user client 2000 and applying a preset scale enlargement or reduction ratio. For example, when the screen size of the user client 2000 is equal to or larger than the reference size preset in the service server 1000, the map image file is scaled up at a preset ratio, The map image file can be scaled down at a preset ratio. For example, when the screen resolution of the user client 2000 is equal to or larger than the standard resolution set in advance in the service server 1000, the map image file is scaled up at a preset ratio, and the screen resolution of the user client 2000 is When the service server 1000 is less than the preset reference resolution, the map image file can be scaled down at a preset ratio. You can zoom in and out by linking the screen size and resolution together.

In step S4, the service server 1000 transmits the map image file to the user client 2000 as map information corresponding to the geotagging information.

For example, the map image file transmitted to the user client 2000 may be displayed on the screen of the blog, SNS,

Through the display of the map image, the user can visually and intuitively recognize the position of the originally photographed photographic image on the map. Since the display of the map image is performed in the form of display of an image file of a general web browser or display of an image file of a blog application without driving a separate map display dedicated application in a user client, There is an advantage that the sending and receiving and rendering processing need not be done at the user client. This advantage is particularly useful when the computing resources of the user client are relatively limited mobile terminals (e.g., smart phones).
