Description
  • Transforms the given shape from its current spatial reference system to one specified by dest_srid.Transforms the given shape from its current spatial reference system to one specified by dest_srid. Two optional arguments: the SRID of the resulting shape is set to dest_srid but the conversion is done by proj4 using origin_proj4_string for projection of original shape and dest_proj4_string for the result. If orig_proj4_string or dest_proj4_string argument is passed but is NULL instead of string, the projection corresponding to original or destination SRID is used. ST_Transform is provided by a separate plugin named v7proj4, as described below. When the plugin is loaded, functions like ST_Intersects() support pairs of arguments with different SRIDs by converting coords of second argument into the system of the first one, as required by OGC and GeoSPARQL.
