This document defines a mechanism for embedding observation footprint description, emphasizing how those descriptions could be attached to DAL query responses or describe instruments signature.Software with interfaces conforming to this specification will enable automatic overlay of observational data with a World Coordinate System obtained from multiple image and spectrum servers or observing tools, regardless of map scale and for various projections and coordinate systems. By itself, this is an extraordinarily useful capability, but it also provides one foundation for interoperability involving more sophisticated capabilities such as proposal preparation.
