I spent a very brief time looking at this for WA this afternoon. To my horror I have discovered a large number of elements that have one of the GNIS ID tags but do not have a name= tag. The few I clicked through were from folks moving the name to another (presumably more accurate?) element and abandoning the GNIS tags on the old element. Ugh.
This is orthogonal to my proposed project but I wanted y’all to get to follow along in my slow descent into the abyss.
