Feature Representation

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this section.

ECW features specify a matrix of x, y, and z coordinates. For each raster, there will only be a single feature returned.
