Conservation Applications of LiDAR: 2009 Conference
Adapted from Water Resources Center webpage
On June 4, 2009, the University of Minnesota Water Resources Center hosted a conference in Rochester, Minnesota to exchange information on soil and water conservation applications of the newest LiDAR data that has just become available for southeast Minnesota.
The conference was attended by technical staff from Soil and Water Conservation Districts, the Natural Resources Conservation Service, Watershed Districts, and county planning agencies. Presenters from Minnesota, Iowa, and North Dakota provided an overview of the range of applications now or soon to be available.
The conference agenda, presentations, and three training videos are online. The 5-minute videos cover the following topics:
  • Terrain Attribute Applications
    An example of how terrain attributes may guide conservation efforts.
  • Data Pre-processing
    Creating a hydrologically corrected Digital Elevation Model (DEM) with LiDAR contours or spot elevations.
  • Terrain Attribute Calculation
    Calculating basic primary and secondary terrain attributes such as Stream Power Index with a DEM.
The videos were developed and narrated by Jake Galzki and Joel Nelson of the U of M Department of Soil, Water, and Climate, and produced by David Lindeman of the U of M OIT Video Solutions. Funding was from the Clean Water Legacy Act, through the Minnesota Department of Agriculture, under Project Managers Adam Birr and Barbara Weisman.
“LiDAR” stands for Light Detection and Ranging and provides high resolution digital elevation data. The current map of LiDAR coverage in Minnesota is available from the Digital Elevation Committee of the Minnesota Governor’s Council on Geographic Information.
