Geotagging Mobile App Development

We would like to collaborate with students to implement a new app that 1. geotags specific points while a tourist (the user) is on a trip and allows their photos at that geotag location to be uploaded to the cloud 2. shares those geotag locations and photos with others that are on the same trip. The app will have the following functions: Allow registration of 2 types of users - administrators and end-users Administrators would use the app, once logged in, to upload specific maps of the travel areas tourists (users) are most likely to go to. Allow end-users to geotag their exact location on the uploaded map and then allow photos from that location to be uploaded and shared
