P_GEOMETRY_2D_GIS (PTY_GEOMETRY_2D_GIS)

(DDL)

The coordinate positions of an object on the earth's surface in a two dimensional coordinate system. This utilizes the format of the OpenGIS Well Known Binary representation for geometry (WKBGeometry) with the exception that byteOrder is not specified and all values are double precision. The assertion is that any two positions with the same x,y values are concurrent (i.e., have the same vertical location) and the object can be fully defined by only specifying the geometry at the boundaries (i.e., the interior geometry is inherently that of the surface of the earth).
