Had a friend ask me via facebook...
"Do you know where I could locate a map that shows all topography over 5000 ft above sea level in the contiguous United States?"
I wouldn't even know where to start other than Google.
Any help is appreciated.

THIS IS ABOUT AS GOOD AS IT GETS....
YOU can CLICK ANY WHERE AND IT WILL GIVE YOU AN XYZ LOCATION.
Accurate too, at least all of the points I've checked...
Most of it would look like islands, right?
Kind of a reverse image of the best cellular service maps.
That's what I'm thinking my friend wants.
Here's a rough contour map of everything above 5000ft in the US, with contours at 1000ft intervals. It's rough, but doing better would take a few hours of processing.
I downloaded a nationwide DEM, reduced it to .04 degree post-spacing and queried everything above 5k, then ran a contour over it.

Edit: Updated version but still no guarantees.
Thank you!!
There aren't any elevations above 5,000 east of the Mississippi?
Mount Katahdin
Highest point in Maine
5,270 ft (1606.4 m)
I worked in that area back in 83 & 84, which is why I remember that one. There may be others too.

I'm guessing my reduction in post-spacing eliminated many of the smaller areas, result of the sampling theorem.
Edit: I ran a test, one hillside in Maine shows up above 5k.

The 0.04 degree resampling created a post spacing of about 10,000ft in Maine, the hillside is about 3,00 feet at it's widest. Fell between the cracks.
