Suppose an app of mine has collected data on walking paths in a particular area. I want the app to find the closest path to the user, but I want the app to download only GPS coordinates that will allow the app to figure out the closest path.
I'm thinking that what I could do is tell the app to only log a contributing user's location when either the contributing user makes a significant turn or his or her bearing to some predefined point on the map becomes significant.
