Well-known binary representation

You can generate a geometry from the OGC well-known binary (WKB) representation. The WKB representation is a contiguous stream of bytes. It permits geometry to be exchanged between a client application and an SQL database in binary form.

ST_GeomFromWKB()

The function creates an ST_Geometry from a WKB representation of any geometry type.

ST_PointFromWKB()

The function creates an ST_Point from a point WKB representation.

ST_LineFromWKB()

The function creates an ST_LineString from a linestring WKB representation.

ST_PolyFromWKB()

The function creates an ST_Polygon from a polygon WKB representation.

ST_MPointFromWKB()

The function creates an ST_MultiPoint from a multipoint WKB representation.

ST_MLineFromWKB()

The function creates an ST_MultiLineString from a multilinestring WKB representation.

ST_MPolyFromWKB()

The function creates an ST_MultiPolygon from a multipolygon WKB representation.

ST_AsBinary()

The function converts an existing geometry value into well-known binary representation.
