Reply to "Elevations from various sources"

AdminMember

Pete,
Are you getting different results from "USGS Map" and "USGS Seamless Viewer" because you are not picking the same exact point? It seems like both of those sources would be using the same data.
For the seamless viewer you could use the "US Grid National Query Tool" which is on the bottom-left under Query. You can convert latitude-longitude to USNG with

http://www.ngs.noaa.gov/cgi-bin/usng_getus.prl

This weekend I'm going to repeat your experiment by finding the latitude, longitude, and elevation of the start and finish of a few of my courses, and then compare the elevations of those lat-long points with the Seamless Viewer result.

Thanks for sharing this tool.
