GMap provides planetary geological maps of different Solar System bodies, developed by an open community, reviewed by scientists. GMap inherits its data model from Planmap, most of the maps provide morphological information, some provide stratigraphic or compositional information too. Each original data packages provided is a collection of vector, raster, and, in some cases, 3D models. In this EPN-TAP service, the data records (granule_uid) refer to each of the data files in the whole of GMAP archive, grouped by (granule_gid) the data package --map-- they compose.
