#initialize(source_dataset, destination_dataset: nil, **options) ⇒ GeneralImageProjectionTransformer2

Returns a new instance of GeneralImageProjectionTransformer2.

Parameters:

  • source_dataset (GDAL::Dataset, FFI::Pointer)
  • destination_dataset (GDAL::Dataset, FFI::Pointer) (defaults to: nil)
  • options (Hash)

Options Hash (**options):

  • src_srs (String) —

    Use to override source_dataset‘s WKT SRS.

  • dst_srs (String) —

    Use to override destination_dataset‘s WKT SRS.

  • gcps_ok (Boolean) — default: true
  • refine_minimum_gcps (Integer) —

    Minimum amount of GCPs that should be available after the refinement.

  • refine_tolerance (Float) —

    The tolerance that specifies when a GCP will be eliminated.

  • max_gcp_order (Integer) —

    Max order to use for GCP-derived polynomials, if possible. Default is to auto-select based on the number of GCPs. A value of -1 triggers use of Thin Plate Spline instead of polynomials.

  • src_method (String) —

    GEOTRANSFORM, GCP_POLYNOMIAL, GCP_TPS, GEOLOC_ARRAY, or RPC. Use this specific geolocation method when transforming pixel/line to georeferenced space on the source dataset.

  • dst_method (String) —

    GEOTRANSFORM, GCP_POLYNOMIAL, GCP_TPS, GEOLOC_ARRAY, or RPC. Use this specific geolocation method when transforming pixel/line to georeferenced space on the destination dataset.

  • rpc_height (Float) —

    A fixed height to be used with RPC calculations.

  • rpc_dem (String) —

    Name of a DEM file to be used with RPC calculations.

  • insert_center_long (Boolean) — default: true —

    False disables setting up a CENTER_LONG value on the coordinate system to rewrap things around the center of the image.
