If anyone is using google-altitude, it's just a local average and not accurate. My property has a bit of a valley in the back and my Bosch transit level says it's about a 16 ft drop. I had a link to a web site that doesn't exist anymore that gave an accurate altitude where it showed the 16 ft and would give me in fractions of an inch as I moved it down my driveway which has a gradual slope. Google shows my entire property as the same 562.2 ft wherever I move it. I checked a lot of tracks with the accurate site a few years ago, It showed Beaver uphill about 17-20 ft I think, but Numidia, Englishtown Atco, Leb Val, NE Dragway, Island and most NHRA tracks to be level within a few inches. It showed Miramichi Dragway Park, I think Cecil and Sacramento, CA to be downhill. I wish I could find an accurate site but can't seem to, the test is easy, my driveway.
