logical; use PostGIS Enhanced WKT (includes srid) |
The returned WKT representation of simple feature geometry conforms to the
simple features access specification and extensions (if EWKT = TRUE),
known as EWKT, supported by
PostGIS and other simple features implementations for addition of SRID to a WKT string.
st_asewkt() returns the Well-Known Text (WKT) representation of
the geometry with SRID meta data.
