Digital Elevation Committee

Final reportThe committee was sunset 3/22/17. A new 3D Geomatics Committee has been formed to carry on relevant parts of its work.

The committee worked to promote the creation of statewide digital elevation data that is consistently accurate and available to the public, and advises MnGeo.

The Digital Elevation Committee was formed under the auspices of the former Minnesota Governor's Council on Geographic Information on September 20, 2006, continuing the work of Minnesota's Digital Elevation Working Group which functioned for years on a mission to improve Minnesota's elevation data. The LiDAR Research and Education Subcommittee formed in August 2010.
