Landsat-8 on AWS 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).

Bands can use 8-bit or 16-bit color types or UInt types.

User attributes are not supported.
