Visually differentiate imports vs. remote mapping vs. ground data collection in heat maps

[TylerRadford]

When looking at places like the US with large imports of road data, it's very hard to tell which areas have had significant manual editing. Would be nice to have a toggle to easily see at a glance which places have had heavy volunteer contributions. Similarly for buildings, is everything in an area building=yes or have more detailed attributes been collected that are likely only possible from a ground survey. What % of buildings are building=yes vs. something else? This is just one example but there are probably more things we can do too.
