So, first of all, you can apply for this patent, because the patent itself will not infringe, but if you want to develop this software and it is discovered by the map website, he can sue you for infringement, so you must go through his authorization if you want to use this function; So about the competition in the same industry, then this is related to the authorization agreement you signed with the map website. If you can get exclusive authorization, it means that he promises to authorize only one company that makes this similar product, so it is impossible for peers to develop it ~
I am a patent agent. I hope the answer will help you ~ hehe
