I can't believe you guys are arguing over a few feet. If you hover over a house on Google Earth, you'll usually be within a few feet (assuming you have buildings turned off). Non-survey grade GPS can be off vertically by quite a bit. 

 

Plus, most weather stations are elevated 10m, right?

2m

The topo maps are all pretty accurate here. I was actually defending Kevin...940/960/980'....whatever. It's all almost 1kft.

That's what I meant about google, and any gps that geolocates and gets an altitude based on Google's maps, not being accurate. That site shows the edge of my backyard being 10' higher than my front yard. My yard slopes the opposite way.

Usgs is the way to go.

Ahh you beat me to it.

The maps will be much more accurate than say a phone or Garmin's GPS. If a map says 960ft but a phone says 1,005ft or whatever, go with the map every time.
