STGeomFromWKB
ST_GeomFromWKB is a spatial database function that converts a Well-Known Binary (WKB) representation of a geometry into a geometry object. It is commonly used in PostGIS and related spatial extensions to translate binary geometry data into usable geometric types such as POINT, LINESTRING, and POLYGON. The function reads WKB data and returns the corresponding geometry in the database’s geometry type system.
Input to ST_GeomFromWKB is typically a binary value that encodes a geometry in WKB format. In standard
Syntax generally includes variants such as ST_GeomFromWKB(wkb) and ST_GeomFromWKB(wkb, srid). The exact syntax can vary by
Notes on behavior: ST_GeomFromWKB validates the input and will raise an error for invalid WKB data. It
