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.

When writing a raster using the Z-Map Grid writer, the values of these attributes are ignored, and the corresponding properties are derived from the input raster.
