Hello - Another user set up a place for a river watershed in Minnesota and Wisconsin in 2016. It’s great, but it doesn’t include the whole watershed. I have the correct KMZ file. Is there any way to amend a place’s boundaries?
The kmz file had both a version of the full watershed, and a group of subsets of the watershed. The subsets didn’t exactly sum to the total – the boundaries were slightly different in the northeast. I put up the full version of the watershed, but check if the northeast boundaries are to your satisfaction. It would easy enough to sum the subsets and make a new full version instead.
