WebThe WKT and WKB standards specify a format only; the semantics of WKT/WKB objects depend on the reference system - for example, a plane or a sphere. The GeoJSON standard, on the other hand, specifies both a format and its semantics: GeoJSON points are explicitly WGS 84 coordinates, and GeoJSON line segments are supposed to be planar edges …
