The <br />original project quantified coastal change from more than <br />2,000 lidar data sets on 3,290 km of Gulf of Mexico and <br />east US coastline using a grid-based approach to measure <br />shoreline and volume differences within GIS using a <br />custom Python-coded system. Following Hurricane <br />Matthew, the JALBTCX toolbox was updated to rapidly <br />quantify shoreline and volume change to allow for USACE <br />to provide their Districts shoreline and volume change <br />quantifications within five days of lidar data collection. This <br />information has been critical for USACE to know where and <br />how much damage was caused by the storm and provided <br />the data needed to justify where emergency response was <br />necessary. USACE continues to utilize this tool following <br />their emergency response surveys. <br />The current project is updating the JALBTCX toolbox by: 1) converting feature extraction tools to Python <br />and incorporating into the JALBTCX toolbox, 2) making edits to the JALBTCX toolbox to streamlining the <br />processing steps, 3) updating the <br />JALBTCX toolbox to allow for multiple <br />datasets, and 4) updating the CRI and <br />incorporating into the JALBTCX toolbox. <br />CPE has converted a USACE developed a <br />feature extraction tool using Matlab to <br />ArcGIS Python. The tool extracts the <br />shoreline position, dune toe, dune <br />crests, and beach slope from survey and <br />lidar based profiles. CPE reviewed the <br />tool and developed ArcGIS Python <br />scripts to replicate the Matlab functions, <br />tested the scripts, validated the scripts <br />with existing data, and developed a <br />tutorial to teach future users. <br />CPE has updated the JALBTCX toolbox to <br />be more streamlined and process <br />PROJECT DETAILS <br />Client Contact Information <br />U.S. Army Corps of Engineers <br />Jennifer Wozencraft, Director <br />7225 Stennis Airport Road <br />Suite 100 <br />Kiln, MS 39556 <br />Phone: 228-252-1101 <br />Fax: 228-252-1133 <br />Jennifer.M.Wozencraft@usace.army.mil <br />Dates of Services: 2020 – Ongoing <br />Current Contract Amount: $170,000 <br />Services Provided <br />› Shoreline and Volume Change Assessments <br />› Beach and Dune Resiliency Quantification <br />› Lidar / Remote Sensing <br />Volume change at Flagler Beach due <br />to Hurricane Matthew.
