I applaud the efforts by Paul and his team. Users should read the accompanying metadata so they know what they're getting and how the data was generated. There is a great deal of difference between lidar, ifsar, and photogrammetrically derived elevation data.

We are in the process of adding this new data from UMN to the Alaska Elevation archive at http://maps.dggs.alaska.gov/elevationdata/  Both the mosaic datasets and the source strips should be available for download within the next couple of weeks, (starting with the mosaics.)
