Tourist GPS Navigator App

Project Desciption

I would like to create an APP as a tourist guide in cities. So I need a standard navigator GPS feature that creates a route and guide me across every single street until the desired places and monuments. I don’t know if we need to create new maps or we can use existing maps and integrate them in our APP. I would like to integrate the camera feature in the APP, so I would be able to take pictures while I’m following the track and use it as a checklist of places in order to know if i have achieved the expectations on my trip. I would like to set/add/modify/update places easily.

Thank you in advance.

Best Regards
