The Texas Natural Resources Information System (TNRIS) is pleased to announce the release of approximately 9167 square miles of newly acquired high resolution lidar data for portions of the Texas coastal region. This project was managed by the Texas Strategic Mapping (StratMap) Program and utilized the StratMap Contracts held by the Department of Information Resources (DIR). Collection took place during the leaf-off season in Texas.
The StratMap contributing partners for this project were the Texas Water Development Board(TWDB), the Houston-Galveston Area Council of Governments(H-GAC), and the United States Geological Survey(USGS) 3-D Elevation Program. Lidar acquired from this project will be used for floodplain management and planning, feature extraction, water quality modeling, stream restoration potential analysis, change detection, 9-1-1, wildfire mitigation, habitat identification/modeling for endangered species, and hurricane recovery projects. Data acquisition and processing was performed by Fugro USA Land with third-party QA/QC being performed by AECOM. The project area of interest covers areas where previous lidar data were acquired a decade ago.
Further details regarding this acquisition can be found by downloading the StratMap 2018 Upper Texas Coast Project Reports.
