Fred queried: > Google Earth is about 7 feet less that > that at the airport. Is it using a different datum from USGS maps? My map is a bit long in the tooth. 1927 North American Datum. 1940 surveys revised 1961. Ticks to move it 2 meters to 1983 datum. > The same map shows the NE end of the small > runway of the airport at 607 and a 600-foot > bench about 3/4 of the > way west on the large runway. That's exactly what I am seeing, with the SW end of the short runway at 590 ft. Odd.
