Cleaning LiDAR Tiles: Tug and Barge

Cleaning more LiDAR tiles today.  This one includes a Tug and Barge combination that I found in the middle of the Mississippi River near New Madrid, Missouri.  No one will ever know it was there when I get done with the tile.  The top view is a cross section elevation and shows what the elevations look like from the side.  The bottom view is an overhead look at the Tug and Barge.

New LiDAR Project

Half way done tonight with our 5 week LiDAR classification/cleanup project for the Arkansas Department of Fish and Wildlife. The screenshot below is a 1 mile by 1 mile tile that includes over 8 million points. Airborne LiDAR uses an aircraft equipped with a laser scanner to image the earth’s surface. It doesn’t take color pictures, but takes a snapshot of the earth’s elevation. So the below tile includes a creek running through a culvert under a road. The creek is the lowest elevation and is represented by a magenta color. The road is the highest elevation and is represented by a green color. I enjoy working with LiDAR and the tools you can produce from the data. It just takes forever to process, classify, and clean up.
