"""
The OGRGeometry is a wrapper for using the OGR Geometry class
(see https://gdal.org/api/ogrgeometry_cpp.html#_CPPv411OGRGeometry).
OGRGeometry may be instantiated when reading geometries from OGR Data Sources
(e.g. SHP files), or when given OGC WKT (a string).

While the 'full' API is not present yet, the API is "pythonic" unlike
the traditional and "next-generation" OGR Python bindings.  One major
advantage OGR Geometries have over their GEOS counterparts is support
for spatial reference systems and their transformation.

Example:
 >>> from django.contrib.gis.gdal import OGRGeometry, OGRGeomType, SpatialReference
 >>> wkt1, wkt2 = 'POINT(-90 30)', 'POLYGON((0 0, 5 0, 5 5, 0 5)'
 >>> pnt = OGRGeometry(wkt1)
 >>> print(pnt)
 POINT (-90 30)
 >>> mpnt = OGRGeometry(OGRGeomType('MultiPoint'), SpatialReference('WGS84'))
 >>> mpnt.add(wkt1)
 >>> mpnt.add(wkt1)
 >>> print(mpnt)
 MULTIPOINT (-90 30,-90 30)
 >>> print(mpnt.srs.name)
 WGS 84
 >>> print(mpnt.srs.proj)
 +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs
 >>> mpnt.transform(SpatialReference('NAD27'))
 >>> print(mpnt.proj)
 +proj=longlat +ellps=clrk66 +datum=NAD27 +no_defs
 >>> print(mpnt)
 MULTIPOINT (-89.99993037860248 29.99979788655764,-89.99993037860248 29.99979788655764)

 The OGRGeomType class is to make it easy to specify an OGR geometry type:
 >>> from django.contrib.gis.gdal import OGRGeomType
 >>> gt1 = OGRGeomType(3) # Using an integer for the type
 >>> gt2 = OGRGeomType('Polygon') # Using a string
 >>> gt3 = OGRGeomType('POLYGON') # It's case-insensitive
 >>> print(gt1 == 3, gt1 == 'Polygon') # Equivalence works w/non-OGRGeomType objects
 True True
