Texas Coastal Lidar Project Delivering high-resolution lidar elevation data surrounding Houston and the coast to Bay City, covering approximately 10,000 sq. miles. Floodplain management and planning APPLICATION Feature extraction Water quality modeling Stream restoration potential analysis Change detection Emergency management services 3 www.fugro.com
Texas Coastal Lidar Project Fugro USA Land, Inc. (FUSALI) Participants Harris County Flood Control District (HCFCD) Houston Galveston Area Council (HGAC) Texas Natural Resource Information Systems (TNRIS) United States Geological Survey (USGS) 4 www.fugro.com
The Coastal Project HGAC project was developed prior to Hurricane Harvey, although since Harvey the need for high-resolution lidar has increased Data will be used for post-storm studies and restoration 5 www.fugro.com

Products Point Cloud “Every lidar point that is post - processed can have a classification that defines the type of object that has reflected the laser pulse. Lidar points can be classified into a number of categories including bare earth or ground, top of canopy, and water. The different classes are defined using numeric integer codes in the LAS files.” … arcgis.com 15 www.fugro.com
Product Use Case: San Antonio River Authority Fugro acquired 4ppsm lidar over San Antonio in 2017 Lidar classified point cloud for vegetation cover raster products Lidar classified point cloud for 1-foot contours 16 www.fugro.com
