LiDAR Training Videos
Return to "Conservation Applications of LiDAR"
The following 5-minute videos describe how to process LiDAR data within ArcGIS to help identify critical areas on the landscape for conservation purposes.
Hint: To see these videos on a full screen, click on the square box near the right side of the control bar at the bottom of the video.
The videos were developed and narrated by Jake Galzki and Joel Nelson (firstname.lastname@example.org, 612-625-9235) of the University of Minnesota Department of Soil Water and Climate, and produced by David Lindeman (UM OIT Video Solutions). Funding was from the Clean Water Legacy Act, through the Minnesota Department of Agriculture (MDA), under Project Managers Adam Birr and Barbara Weisman.
