Abstract(s)
SUMMARY: The Portuguese Geological Survey (LNEG) provides the Geological Digital Map of Portugal (online version) through its geoportal. This product is supported by a data model (DM) that implements a hierarchical catalog of lithostratigraphic and lithodemic units. The DM is linked to an INSPIRE compliant geodatabase. The developed geological model provides a synthesis of published maps, with ongoing steps toward harmonisation and interoperability. This paper describes several aspects of the database implementation and its characteristics. The obtained database will allow to: (i) produce a seamless 2D geological map; (ii) solve the inconsistencies that become visible when changing the scale of representation (from 1:25 000 to 1:200 000); (iii) fulfill the INSPIRE requirements. It also highlights some cartographic problems that require further research and field survey to be solved.
