Overview of spatial data types

The geographic information system (GIS) feature of seekdb supports the following spatial data types:

• GEOMETRY

• POINT

• LINESTRING

• POLYGON

• MULTIPOINT

• MULTILINESTRING

• MULTIPOLYGON

• GEOMETRYCOLLECTION

The POINT, LINESTRING, and POLYGON types are the basic types for storing single spatial data. They are extended from the MULTIPOINT, MULTILINESTRING, and MULTIPOLYGON collection types, respectively, to store collections of spatial data. However, they can only represent collections of their respective basic types. The GEOMETRY type is a virtual type that can represent any basic type. The GEOMETRYCOLLECTION type can be a collection of any GEOMETRY type.
