A geographic database is part of a geographic information system (GIS). It collects spatial data that can later be used for analysis and presentation.
The essential basis of every geo database is the object-relational data model customary for such systems. A geo database is optimized for processing spatial data. It differs from traditional databases by using additional data types, which are usually based on the standard of the Open Geospatial Consortium (OGC). Geodatabases are often created by expanding classic database systems with the appropriate software.
This digitally maps spatial data, processes and objects and places them in the appropriate relationships to one another.
