Table sola_cs.cadastre.spatial_unit
Single area (or multiple areas) of land, water or a single volume (or multiple volumes) of space.
Implementation of the LADM LA_SpatialUnit class. Can be used by SOLA to represent geographic features such as place names and roading centrelines that are not considered as cadastre objects.
