National Recreation Model
I noticed when doing an assessment of recreation value that you can end up with a single area with extremely high PUDs that corresponds to the lat/long Google places for an something. In my case, the Google lat/long for a country. In Namibia this happened to be placed in the middle of no-where so was easy to pick up and because of low densities of photos, the assumption to remove all of them seemed appropriate. This could potentially be a problem for other areas, where it is uncertain what proportion of the number is due to this vs. actual photos taken.
Any thoughts on how to avoid this in future?
