The Texas Natural Resources Information System (TNRIS) is pleased to announce the release of approximately 484 square miles of newly acquired high resolution lidar data for portions of Crockett County. 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 partner for this project was the Texas Commission on Environmental Quality (TCEQ). 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 dam safety. Data acquisition and processing were performed by the Sanborn Map Company. The project area of interest covers a gap in Texas where no lidar data previously existed.
Further details regarding this acquisition can be found by downloading the Project Report(s) found in the DataHub entry.
Lidar data and the associated geospatial products for this project are available for the cost of reproduction through the TNRIS Research and Distribution Center (RDC).
