World Meteorological Organization GRIB (GRIdded Binary) 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.
