transform
-
transformation
Apply arbitrary coordinate transformation to the geometry.
This method will transform the coordinates of a geometry from their current spatial reference system to a new target spatial reference system. Normally this means reprojecting the vectors, but it could include datum shifts, and changes of units.
Note that this method does not require that the geometry already have a spatial reference system. It will be assumed that they can be treated as having the source spatial reference system of the CoordinateTransformation object, and the actual SRS of the geometry will be ignored.
Parameters:
-
transformationgdal.CoordinateTransformation
union
-
geometry
Compute the union of this geometry with another.
Parameters:
-
geometrygdal.Geometry
Returns:
gdal.Geometry
within
-
geometry
Determines if the current geometry is within the provided geometry.
Parameters:
-
geometrygdal.Geometry
Returns:
Boolean
