Hi Daniele, That is indeed the expected behavior. Since polar stereographic is just a special case of stereographic, we decided to always just emit *:grid_mapping_name = "stereographic"*, as it made our implementation easier. We could be convinced to change it, but probably only if the current implementation is causing something to break. Was your message in response to a problem you've encountered or were you just double-checking our work (which we appreciate!)?
