Hey Dimka,
great that you have the time for the second stage 
I’m not sure if this is possible but I would add a node for the site.
Additionally I would add automatically a boundary around it and define it like the site.
It would be perfect if we could add nodes in this boundary for parking, picnicsite, restroom etc.
This way you would have all data setup in place. Then we would need to go over those boundaries manually to check if sat images are more effective.
If we could have a list to go through we would be finishing it very fast.
Is this possible?
