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.

Yet the GPS devices all are much higher than that. Interesting

Oh and I live here

I'm not getting into what elevation you live at only to say the topo-maps these days are dead on accurate and I'd take that over a GPS that probably has a range of +/- 50-100ft at least.

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.

I checked a point in my side yard where I've used survey grade GPS (2 sigma about 0.15') and it's off by about a foot. Google Earth is more accurate in some areas than others.

lot of trees down in Western Coventry out by CT line, we have 3 details out there now with national grid

not far from me, lots of debris down, saw some trees down on the edge of the road but it was dark. Moved two good size branches out of the driveway when I got home.
