Better Data Source

[RainOn]

Have you considered using a better source of DEM data with patched voids, such as http://www.viewfinderpanoramas.org/dem3.html, on your running service: jthatch.com? Also see: https://github.com/migurski/Viewfinderpanos-Index

I would love to have a void filled DEM! Is all the data on that map void filled? If so, I'll get right on that!

Alright I just tested a few of those out. I looked at a spot in Glacier National Park, a place that I've noticed has a lot of voids. The viewfinderpanorama DEM had fewer voids, but it's not perfect. On the other hand, I noticed that some small voids were fixed in a couple other places I checked. What do you think?

I've used this data source for all of the international (i.e. outside USA) mountain models I have created with very good results: http://www.thingiverse.com/MadisonMtng/designs.

Did you see the about page on the data set: http://www.viewfinderpanoramas.org/dem3/DEM3-ReadMe.html
