Live location of the smartphone as a "source mission"
Now when you want to create a mission you have two kinds of sources: Osmose and Overpass. My question is...Why don't cross this data with live location of the smartphone? Why a third source: "live location". Then you would have a very good app for doing mapathons from everywhere with the conditions of everywhere. With this source you don't need street imagery source ...because the reality is the source.
