Instructions for use
In the process of using Map Tiles, you may encounter changes in Map Service data, such as changes in the style of a certain layer in the map, or the addition, deletion or modification of elements in a certain layer. In this case, you need to update the existing Map Tiles to ensure the timeliness of Map Tiles.
The update Tile function supports the update operation of Raster Tile and Vector Tile, supports the update of Tile in specific scale and different Tile Bounds, and automatically overwrites outdated Tile.
Tile updates are supported in both Single Task and Multiple Tasks. The entries of the two map cutting methods are different, but the update principle is the same. The existing Tile is updated by re-specifying the Tile Bounds and scale to be updated through the set Map Tiles configuration *.sci file.
Caution: If a single-task Generate Map Tiles is used, a single-task update is also required when updating; and if a multi-task Generate Map Tiles is used, a multi-task update is also required when updating.
Function entrance
- Single-task Update Tile: It is consistent with the single-task graph cutting function entry. Select Update/Append Tiles in the first pop-up dialog box.
- Multitask update Tile: Consistent with the Generate Map Tiles by Multiple Tasks function entry. On the first dialog, select Update/Append Tiles
Parameter Description
When updating the Raster Tile and Vector Tile, the parameters that support setting are slightly different. Both support setting the scale bar and Tile Bounds.
- Scale: In the Update Map Tiles dialog box, you can modify the cutting scale by specifying, adding, deleting, etc.
- Tile Bounds: On the Bounds Parameter panel, set the Scope of update. Default range refers to the range set when cutting.
- Vector Tile Update: Since tiles, tile styles, and tile font files are stored separately during Generate Vector Tile, they can be updated independently. It is controlled by three check boxes of Generate Vector Tile, Generate Tiles Style, and Generate font cache file, and supports setting of Tile Range.
- Completely fill the tile: must be checked by default. Otherwise, the results in the Tile directory will be affected, but the display of the tile will not be affected.
Caution: The Index Bounds are not updatable and are consistent with the Index Bounds of the original *.sciTile file, which is convenient for indexing to the Tile in the Specify Range.
Execute the cutout
- If the single-task update Tile is used, the single-task update Tile operation can be performed directly after the update Tile parameters are set.
- If multi-task update Tile is used, after updating TileParameter Settings, click Next, the Generate Map Tiles by Multiple Tasks dialog box will pop up, and the user needs to set the number of tasks for multi-task update Tile. For a detailed description of the Generate Map Tiles by Multiple Tasks, refer to the Generate Map Tiles by Multiple Tasks.
Caution: the Tile is updated successfully, a new *.sci will be generated under the result folder according to the update parameters, and only the parameters set during the update are recorded in this file. At the same time, the original.sci file will be automatically updated to the changed Tile parameters, and the parameter information of the original.sci file will be more complete.
