ST_PointFromWKB — Makes a geometry from WKB with the given SRID
geometry ST_GeomFromWKB(
bytea geom)
;
geometry ST_GeomFromWKB(
bytea geom, integer srid)
;
The ST_PointFromWKB
function, takes a well-known binary
representation of geometry and a Spatial Reference System ID (SRID
)
and creates an instance of the appropriate geometry type - in this case, a
POINT
geometry. This function plays the role of the Geometry
Factory in SQL.
If an SRID is not specified, it defaults to -1. NULL
is
returned if the input bytea
does not represent a
POINT
geometry.
