    transform
    (
    • transformation
    )

    Inherited from gdal.Geometry: src/gdal_geometry.cpp:361

    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:

    transformTo
    (
    • srs
    )

    Inherited from gdal.Geometry: src/gdal_geometry.cpp:380

    Transforms the geometry to match the provided SpatialReference.

    Parameters:

    union
    (
    • geometry
    )

    Inherited from gdal.Geometry: src/gdal_geometry.cpp:447

    Compute the union of this geometry with another.

    Parameters:

    Returns:

    gdal.Geometry

    within
    (
    • geometry
    )

    Inherited from gdal.Geometry: src/gdal_geometry.cpp:316

    Determines if the current geometry is within the provided geometry.
