Feature Description
During the use of map tiles, you may encounter changes in map service data, such as style modifications of specific layers or additions/deletions/modifications of features, which require updating existing map tiles to ensure timeliness.
The tile update feature supports both raster tiles and vector tiles, allowing updates at specific scales and within designated tile bounds to automatically overwrite outdated tiles.
Supports Single-process and Multi-process update modes. Though accessed differently, both methods follow the same principle: Reconfigure the *.sci file with specified update bounds and scales to refresh existing tiles. The update mode must match the original generation method - single-process generated tiles require single-process updates, and vice versa.
Feature Entry
- Single-Process Tile Update: Shares the same entry with single-process map cache generation. Select Update/Append Tiles in the first dialog.
- Multi-Process Tile Update: Shares the same entry with multi-process tile generation. Select Update/Append Tiles in the first dialog.
Parameter Description
Parameters for raster and vector tile updates differ slightly, though both support scale and tile bounds configuration.
Notes:Index bounds remain unchanged and consistent with the original *.sci file to maintain tile indexing within specified ranges.
- Scale: Modify tile generation scales through add/delete operations in the update dialog.
- Tile Bounds: Set update scope in bounds parameter panel. Default range matches original generation settings.
- Vector Tile Update: For vector tiles (storing tiles, styles, and fonts separately), three checkboxes enable independent updates: Generate Vector Tile, Generate Tiles Style, and Generate font cache file, with Tile Range configuration support.
- Completely fill the tile: Enabled by default for raster tiles. Disabling may affect tile directory structure but not display.
- For single-process updates: Start directly after parameter configuration.
- For multi-process updates: After parameters setup, click Next to configure process count in Generate Tile by Multi-process dialog. For details see: Generate Tile by Multi-process.
Notes:After successful update, a new *.sci file containing update parameters will be generated, while the original *.sci file automatically updates with full parameter records.
