Over 87,062 square miles of elevation data (and over 168,285,617,189 points) available!

This interactive map was designed to view and download known public-domain elevation datasets (LiDAR and InSAR) in Alaska.

Information Tool: Single click to get information about a survey area.
Area of Interest Tool: Use this tool to define an area and download compressed point cloud data.
Full screen mode: Toggles map using entire browser window.
Areas outlined in red contain LiDAR data.
Areas outlined in purple contain InSAR data. (We are adding InSAR data as we finish processing.)

Metadata information will be packaged with your download in a README.TXT file. Please contact Ken Woods for more information.

As of April 2015, DGGS is adding new elevation datasets as they become available.
We believe this application currently contains all of the publically available point cloud data available in Alaska. If you'd like to contribute additional data, please contact Ken Woods via email or via telephone.
We are happy to host all publically available elevation related datasets, no matter how small or large.

Please Note: The LiDAR point cloud data has been compressed using LASzip, an open-source, lossless compression scheme. To uncompress the .laz files included in your download package, you can download the latest version from laszip.org or download the tool (for Windows) directly: laszip.exe

Throughout 2015, DGGS will be making digital elevation model (DEM) products available as they are generated.
