Geospatial data is information that identifies geographic features, locations, and boundaries on Earth. By using geospatial data, you can store and analyze geographical information. Points, LineStrings, and areas are defined through coordinates and saved in Exasol as GEOMETRY objects. GEOMETRY columns can optionally have an SRID (Spatial reference system identifier, see EXA_SPATIAL_REF_SYS for more information) a reference coordinate system, which is a kind of constraint.
The GEOMETRY columns are filled with strings (for example, 'POINT(2 5)'). If you read this data externally by the drivers, this data is automatically converted to strings. The same applies to commands IMPORT and EXPORT.
For geospatial objects, a multitude of functions are provided to execute calculates and operations.
