Raw Data Layers

A Raw layer is a traditional GIS data layer - a set of geo-referenced geometry without any higher-level knowledge of the what the geometry represents.  This is useful for types of abstract data which do not have a real existence in the world, such as administrative borders, general reference points, and so on.
