Package io.debezium.data.geometry

Class Geometry

java.lang.Object
io.debezium.data.geometry.Geometry
Direct Known Subclasses:
Geography, Point
public class Geometry extends Object
A semantic type for an OGC Simple Features for SQL Geometry. Used to describe geometries on a planar basis (rather than Geography, which is a spherical basis).

See the Open Geospatial Consortium Simple Features Access specification for details on the Well-Known-Binary format http://www.opengeospatial.org/standards/sfa

WKB has to be forwards-compatible to the spec, so strict OGC WKB, and EWKB (PostGIS) are both ok.
