TransDEM Forum

Good day, I will keep this short and simple. I recently finished a major project thanks to the help of TransDEM. I am about to begin another but however I ran into a problem. As I was going to search for the .UGT files ( terrain ) I needed for the route, I noticed that the website that had all the files stored has been removed and no longer works. Is there an updated place to get terrain data now?

STRM download addresses (as of 04/2021):

• https://e4ftl01.cr.usgs.gov/MEASURES/SRTMGL3.003/ Default 3 arc second data
  for the whole world obtained by averaging the 1-arc-second raw data.
• https://e4ftl01.cr.usgs.gov/MEASURES/SRTMGL1.003/ 1 arc second data for the
  whole world.
• https://e4ftl01.cr.usgs.gov/MEASURES/NASADEM_HGT.001/ NASA-DEM variant,
  1 arc second data for the whole world.

If this is a US route, I would always go for the the much better terrestrial DEMs offered by the USGS National Map Viewer, 1/3 arc sec, or for some places (subject to availability) 1/9 arc sec or even 1 m LIDAR:
