. Used together with source_vertices to define the transformation from the CRS of the geoData to WGS84.
-
faces
¶ List of face definition tuples, each face entry is a 3-tuple of vertex indices (0-based).
-
coordinate_system_definition
¶ The coordinate system definition string. Stored as XML. Defines the CRS used by the GeoData. The EPSG number and other details like the axis-ordering of the CRS is stored.
