This mobile app will collect data from the phone's current GPS coordinates when the user selects a tag for the collected points. Each tag corresponds to an associated icon which gets dropped on the map.
The map is given a unique identifier, and any user who is working off the same unique identifier should see the same map data. So dozens of people could work on the same data collection project and each sees the points the others are tagging.
We are partial to Meteor and React Native, but I'm willing to hear your ideas if you think another platform is appropriate.
I have all the map icons that should be used. The mapping layer should be done with [login to view URL]
The layout and user controls experience is being sketched up now and we'll work together to make a simple UI layout. I don't want too many features or complex workflows. Basically, the user picks a marker type and it gets saved to the project.
I look forward to hearing from all the best spatial app developers! Feel free to ask any clarifying questions you like.
