In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
The WMTS reader delegates all raster tile reading to the FME raster readers.
An instance of WMTS reader produces a feature type that is set to the name of the selected layer.
Additional attributes with values taken from the GetTile request are attached to each downloaded raster. These attributes correspond to information of the returned tiles:
- wmts_tile_row
- wmts_tile_col
Geometry Representation
The geometry of WMTS Reader features is identified by the wmts_type attribute. The valid values for this attribute are:
|
wmts_type |
Description |
|---|---|
|
wmts_no_geom |
FME Feature with no geometry. |
|
wmts_raster |
FME Feature containing the raster tile geometry. |
No Geometry
wmts_type: wmts_no_geom
Features with their wmts_type attribute set to wmts_no_geom do not contain any raster tile data.
Points
wmts_type: wmts_raster
Features with their wmts_type set to wmts_raster are single tile raster features.
