GoogleMap cutting program based on Supermap Objects (3)

The main function of this tool is to output vector map data into image data similar to Google Maps, specifically TMS (Tile map serviceThe image encoding method makes it easy to use the WebGIS API to load these images and publish them as map services like Google Maps, improving the access speed. Of course, you can also load your own business data and integrate it into your current business system. With your own data, you can publish it on a LAN or the Internet.

This is an upgrade based on the previous version. The main changes include:

1. use the new projection configuration. For the new configuration, see configure Google Maps map projection in Supermap desktop. This is because the previous configuration is used to perform secondary projection conversion on map data in the program, so there will be a little difference in accuracy, so a white line or overlapping part will appear when two images are connected in some places.

2. added the TMS number display function. You can better see the range and number of the graph to be cut before you cut the graph.

3. added the "continue previous cut graph" function to enable the program to continue to cut the data that has not been cut down next time when the program is interrupted during the cut graph process.

The main completed functional interface is as follows:

Next we will use fgmap to load the map we have cut out for a test:

The above shows the Beijing map. The map we tested is a national map. The loaded interface is:
