Table sola.source.spatial_source
A spatial source may be the final (sometimes formal) documents, or all documents related to a survey. Sometimes serveral documents are the result of a single survey. A spatial source may be official or not (i.e. a registered survey plan or an aerial photograph). Implementation of the LADM LA_Source class. Not used by SOLA.
