Programs

• Minnesota Elevation Mapping Project
  A State of Minnesota Legacy Amendment project to complete lidar coverage of the state.
   
• 3DEP
  The primary goal of 3DEP is to systematically collect enhanced elevation data over the United States and the U.S. territories.
  • Base lidar specifications
     
• Red River Basin Mapping Initiative
  The goal of the Red River Basin Mapping Initiative was to use lidar to develop a high resolution DEM for the Red River of the North Basin south of the Canada-U.S. border.
