Spatial functions

This section describes the following spatial functions:

  • ST_DISTANCE: Calculates the 2-dimensional cartesian minimum distance between two WKT formatted geometries in the units of the inputs.

  • ST_WGS84_DISTANCE: Calculates the distance between two WKT formatted points in meters in the WGS84 projection

  • WKT_SPATIAL_CONTAINS: Checks if the first WKT formatted spatial object contains the second

  • WKT_SPATIAL_INTERSECT: Checks if the WKT formatted spatial objects intersect
