Return the computed partial derivatives in evansslope#434
Merged
Conversation
GridObject.evansslope previously returned the two gradient filters rather than the filtered DEM. A test is added to verify that this works. The test is a metamorphic test that rotates the DEM and compares the gradients to make sure that they transform as expected. Signed-off-by: William Kearney <william.kearney@uni-potsdam.de>
