cartopy.mpl.geoaxes.InterProjectionTransform¶

class cartopy.mpl.geoaxes.InterProjectionTransform(source_projection, target_projection)[source]¶

Transform coordinates from the source_projection to the target_projection.

Returns: InterProjectionTransform – A Matplotlib Transform from target to source coordinates.

transform_non_affine(xy)[source]¶

Transform from source to target coordinates.

Parameters: xy – An (n,2) array of points in source coordinates.
Returns: x, y – An (n,2) array of transformed points in target coordinates.

transform_path_non_affine(src_path)[source]¶

Transform from source to target coordinates.

Cache results, so subsequent calls with the same src_path argument (and the same source and target projections) are faster.

Parameters: src_path – A Matplotlib Path object with vertices in source coordinates.
Returns: result – A Matplotlib Path with vertices in target coordinates.
