ST_GeomFromEWKT — Devuelve un valor especificado ST_Geometry desde una representación "Extended Well-Known Text" (EWKT).
geometry ST_GeomFromEWKT(
text EWKT)
;
Construye un objeto PostGIS ST_Geometry desde una representación OGC "Extended Well-Known text" (EWKT).
El formato EWKT no es un estándar OGC, sino un formato especifico PostGIS que incluye el identificador del sistema de referencia espacial (SRID). |
Mejora: 2.0.0 se introdujeron soporte de superficies poliédricas y TIN.
This function supports 3d and will not drop the z-index.
This method supports Circular Strings and Curves.
This function supports Polyhedral surfaces.
This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
