Topographical Map of Earth Mission Completed 20
dolphin558 writes "The mission to provide a topographical layout of a large swath of the planet Earth was completed after a four year partnership between NASA and NGA. The data was derived from the Shuttle Radar Topography Mission launched February of 2000. The map extends from 60 degrees north of the Equator to 56 degrees south with a resolution level (for publicly available data) of 295 feet. The data can be used to set warning guidelines for low lying areas, regulate land use and further refine radar topography for extra-terrestrial applications as in the case of Venus."

Ah, well, if you want it done right -
Does anybody know of an OSS package that will let me take a whole bunch of waypoints from a WAAS GPS and build a topo map from it?

GPS does better than 5 meters.

I went to http://seamless.usgs.gov/website/seamless/viewer.
Interestingly, though, there are some dropouts visible in the elevation data under the lake. They don't seem related to depth. I wonder if a party barge on water causes a strange echo?
Works on coastal areas, too. However, since the pebbly texture looks the same for the whole area of Matagorda Beach [matagordabay.com] that I looked at, I suspect I'm not seeing anything but a false echo a few feet below the surface.
