Namespace functions

These functions return information about properties of specific geometry objects. https://postgis.net/docs/reference.html#Geometry_Accessors

These functions create geometry objects from various textual or binary formats. https://postgis.net/docs/reference.html#Geometry_Inputs

These functions convert geometry objects into various textual or binary formats. https://postgis.net/docs/reference.html#Geometry_Inputs

These functions test whether geometries are valid according to the OGC SFS standard. They also provide information about the nature and location of invalidity. https://postgis.net/docs/reference.html#Geometry_Validation

These functions compute measurements of distance, area and angles. There are also functions to compute geometry values determined by measurements. https://postgis.net/docs/reference.html#Measurement_Functions
