When constructing the tile map request address, construct it like http://127.0.0.1/mapservice/ URL address format of data/tilemap/img/1/2/0.png. Create a map container class in Openlayers, add the tile layer object to the map container, and realize the remote call of the tile map service. Finish.

The most obvious difference of the present invention is that it can automatically upload the MapGIS 67 vector map data and its associated font library and system library to the server on the client side, and then call the tile slice interface provided by MapGIS 10 to realize automatic tile slicing. The tile image files are stored on the server side in the form of files and provided to the client in the form of HTTP service. The client can use Openlayers, Leaflet and other map frameworks to call the tile images on the server side for display, which solves the problem that the current MapGIS67 vector map requires manual work. For the problem of generating tile data by slicing, when it is necessary to perform tile slicing on a large number of MapGIS 67 vector maps, the advantages of the present invention are more obvious, and a large amount of labor costs can be saved.

A tiled map online automatic slicing service system that supports MapGIS67 map engineering is characterized in that it includes the following modules: Client path acquisition module, for obtaining the path of MapGIS67 map engineering file at the client, the directory where the map layer file associated with the MapGIS67 map engineering file, the directory where the font library used by the MapGIS67 map engineering file is located and The directory where the system library used by the MapGIS67 map project file is located; The client configuration acquisition module is used to obtain the tile slicing strategy, dynamic projection information, the name tilename saved after the tile slicing, the beginlevel and endlevel of the tile slicing, and the tile file directory organization strategy dirFormat on the client side; The client data sending module is used to use the data obtained by the client configuration acquisition module as an HTTP request parameter on the client, construct it into a json format string, and send it to the server; The server configuration saving module is used to create a folder with the same name as the tile slice in the data saving directory after receiving the data sent by the client in the client data sending module on the server side, and then save the received data Save to the newly created folder; The server path saving module is used to create a new first subfolder in the newly created folder of the server configuration saving module on the server side, and the client sends the data obtained in the step client path acquisition module to the server side, and the server side will receive The path of the MapGIS67 map project file obtained by the client in the client path acquisition module, the directory where the map layer file associated with the MapGIS67 map project file, the directory where the font library used by the MapGIS67 map project file is located, and The directory where the system library used by the MapGIS67 map project file is stored in each directory of the first subfolder respectively; The server interface setting module is used to call the directory environment setting interface provided by MapGIS10 on the server side, and the font library directory and system library directory used when MapGIS10 accesses MapGIS67 version map data are respectively set as corresponding directories in the first subfolder; The server dynamic projection module is used to save the dynamic projection information saved by the module on the server side according to the server configuration, and judge whether dynamic projection is required. If so, the server side calls the map document operation interface provided by MapGIS10, and correspondingly from the first subfolder Open the map project file of MapGIS67 version in the directory of MapGIS 10, call the map document operation interface provided by MapGIS 10, enable dynamic projection, and set the target spatial reference system of the dynamic projection of the map project according to the spatial reference system spatial of the dynamic projection in the dynamic projection information , call the map document operation interface provided by MapGIS10, save the map project file, and then call the tile data processing module; if not, call the tile data processing module; The tile data processing module is used to create a second subfolder in the newly created folder of the server configuration saving module on the server side, and then call the tile database operation class provided by MapGIS10 to create a subfolder in the second subfolder directory Tile database file, then open the map project file that needs to be sliced, obtain the map object, open the created tile database file, call the tile slice interface, and save the map slice in the map project file to the tile database file; The organization strategy processing module is used to create a third subfolder in the newly created folder of the server configuration saving module on the server side, open the tile database file saved by the tile data processing module, and read each tile map level in a loop In each column of each row, the tile image data is stored in the third subfolder directory according to the tile file directory organization strategy dirFormat set by the client configuration acquisition module; The client data calling module is used to call the tile layer class provided by the map development library on the client side to create a tile layer object. When constructing a tile map request address, construct the corresponding address into a URL address format. The constructed address corresponds to the address of the third folder; a map container class is created, and tile layer objects are added to the map container to implement remote calling of the tile map service.
