Discover the spatial data types available in SAP HANA database and understand some core concepts of processing spatial data.
A point is a spatial data type for a 0-dimensional geometry representing a single location
A string ('a curve' in more general) is a spatial data type that connects points
A polygon is a spatial data type that defines a region of space
Using columns to store and process spatial data in tables
Geometries can optionally have Z (3rd dimension) and M (measure) values associated with each point in addition to X and Y coordinates
In the context of spatial databases, the defined space in which geometries are described is called a spatial reference system (SRS).
