Download Free High Resolution DEM - 12.5m from Alaskan Satellite Facility

Hi viewers download high resolution DEM data - 12.5m for Free. Access the data from Alaskan Satellite Facility.

A good video and as @rajeshvg399 mentions, these data are not DEMs derived from ALOS PALSAR. They are derived from SRTM +/- NED (USA). The DEMs downloaded here are used for terrain correction of SAR data. They are upsampled from 30 meters to 12.5 meters

Thank you

This video is very useful. Thank you for uploading this video and expect more such videos from you. I have a doubt in this. The DEM file shows values ranging from -121 to -1. So that can't be the elevation value right ??? So is there any further processing required to get exact Elevation value from ALOS PALSAR DEM. Please reply for the same.
