DBGT10K — Union framework on scale 1:10,000

Spatial area characterised by homogeneous information compared to a synthetic subset of metadata. Each instance of this class corresponds to the section defined in the RNDT. Since several classes may affect the same territorial scope, a section can be considered to belong to different datasets. It follows that a relationship [1..n] must be established between each dataset described and the sections belonging to it. To achieve this result it is necessary to add a relational table that collects the sections belonging to a certain dataset. This table includes the following attributes: — COD_CL ¿class code (string) — SEZ_ID ¿FILE_ID of the homogeneous field for metainformation/section
