"Using LiDAR to Quantify Vegetation Growth and Stream Shade Change"
Presenter: Brian Shepard, Clean Water Services SESSION: Remote Sensing & Lidar Methods
ABSTRACT: Clean Water Services (CWS), a water resources management utility that serves over 550,000 customers in the Tualatin River watershed, contracted with Quantum Spatial, Inc. (QSI), to perform height change and effective shade analyses in support of stream corridor and aquatic habitat enhancement. The results were used to create animations that help to describe the effects of the enhancement efforts as well as provide a higher level of understanding about the environmental stewardship role that CWS fulfills. Datasets of individual tree delineations were created by utilizing point cloud geometry, spatial distribution patterns, and neighborhood analysis. Each tree
