Instructions
Distributes tiles by specifying scales and tile bounds.
The feature applies to distribute large-area tile data. You can specify distribution bounds and map scales without clipping data. For instance, You want to distribute a group of high-resolution image data of a province to each city. You can set the administrative boundary of each city as the distribution bounds and specify scales of map tiles. Then you can distribute image data to each city without regenerating map tiles.
Function Entrances
Data group > Data Management > Tiles Management to open the window Tiles Management. (iDesktopX)
Operating Instructions
- Add tiles to be distributed : Add MongoDB tiles or local tiles. For specific operations, please refer to Load Tiles.
- Distribute : click the Distribute button to open the dialog box Distribute Tile and set the following parameters.
- Tile Name : select the tile you want to distribute. The program will choose the first record by default.
- Scale : the scale list shows all scales of the current map tiles. You can select scales as you want.
- Distribution Range : set the bounds of tiles to be distributed. The program provides four methods to specify the bounds, including Whole Map, Current Window, Custom Bounds, and Copy and Paste. For more detail information on bound settings, please refer to Generate map tiles (single task).
If you want to specify objects as the tile bounds, you need to add the required region layer to the current tile management window first. Then the bounding rectangle of the selected objects will be taken as the distribution bounds.
- Result Settings : specify a MongoDB database to save the resulting data.
- After all settings click OK to perform the distribution.
Application Examples
Given a group of global hill-shading map tiles, we drew a rectangle as the tile bounds and used the original tile scales. Then we got the following result.
