Feature Representation

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).

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