Hi all, one of the reasons why its great to rely on external tools is that they develop a lot of infrastructure.
One of those that I found is the ability to upload imagery that you own the license for to use on the OpenStreetMap editor.
How much interest is there in doing so? It would look similar to your mask, but with maybe slightly higher detail. I think greens/water are very easy to spot, but bunkers are not easy to spot. There is also a HUGE variety in the quality of this data, so only about half of courses would be able to use this AND it won't align any better than the Sat images for now.
