WebMapTiler

Creates a series of image tiles that can be utilized by web mapping applications such as Bing™ Maps, Google Maps™, or Web Map Tile Service. This is done by resampling rasters to various different resolutions and then splitting them into tiles.

Usage Notes

  • Generally, when writing out the rasters generated by this transformer, one would fanout the destination feature type on the quadkey for Bing Maps or a combination of the zoom level, tile column, and tile row for Google Maps. The PNGRASTER writer is recommended for the best results.
  • This transformer accepts only features that have raster geometry and is unaffected by raster band and/or palette subselection.
  • Note that for the best performance, rasters output by this transformer should be written in the order they are output. Changing the order (for example, by using Dataset Fanout or a Sorter transformer) may negatively impact performance. Alternatively, use a RasterCheckpointer after the WebMapTiler, but prior to the operation that changes the order.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
