Create Data

This article introduces how to generate map tiles and use map tiles in two ways. We use SuperMap iDesktopX 10.2 to create data.

Create Map Tiles

  • Double click on the map to open it.
  • Click Maps > Mapping > Map Tiles. In the popup dialog box, set related parameters.
  • Set scales. You can use the default scales or re-specify scales.
  • Set basic parameters: Version to 5.0, Tilling Mode to Local Tile. And then set the nam and path of the resulting data.
    • Figure: Set basic parameters
  • Set bounds: Set the tile bounds and index bounds to the whole bounds of the map. To generate map tiles that use a geographical coordinate system, please set index bounds to left: -180, bottom: -90, right: 180, and top: 90 to display tiles on a mobile device normally.
    • Figure: Set bounds
  • Sets image storage parameters: set Image Type to JPG, Storage Type to Origin for discrete data and Compact for compact data. We recommend using compact data with the block size 512*512.
    • Figure: Sets image storage parameters
  • Click Run to generate tiles.

The resulting map tiles

The resulting folder contains data folders and a sci file as the following picture shows:

The second-level folder includes an inf file and folders named after scales.
