Has anyone else noticed how inaccurate the public land layers are in Google Maps? In standard view, they use a green to suggest where public lands or natural areas are, but the extent and accuracy is widely variable.

Speaking to the area I know around Puget Sound, city parks are fairly accurate, but entire state conservation areas are missing as well as the Mount Baker Snoqualmie National Forest in the central Cascades and thousands of acres of municipal lands.

 

Anyone know where Google sources their data for public lands? It's not hard to download a shapefile of US Forest Service ownership. A great visualization of how poor Google's data can be seen by turning off terrain view on this USFS map viewer. Zoom in a bit and you see the shading; that is what USFS ownership actually is. 

 

Any suggestions for how to encourage Google to improve their public ownership data?

I've certainly noticed it in New Mexico.
