Some of the most robust data we have posted here on the MN Geospatial Commons is our high-resolution elevation data in LiDAR format. A quick way to find those resources on the Commons is to use the "Elevation" tag in your search to obtain results like this (notice how "?groups=elevation" is in the URL).

If you're interested in learning more about this data, please consider viewing a recorded webinar hosted by Tim Loesch, IT Business Services Manager for the Department of Natural Resources. More than 80 individuals attended the webinar on November 25 titled, “The LiDAR Data Catalog for the State of Minnesota”. To view the recording, go to the U of M's site.
