The Texas Natural Resources Information System (TNRIS) is pleased to announce the release of approximately 1,136 square miles of newly acquired high resolution lidar data for a portions of the North East Texas coast. 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) and the Trinity River Authority(TRA). 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. The project Area of Interest covers areas where previous lidar acquisition did not meet USGS Quality level 2 data specifications.
Further details regarding these acquisitions can be found by downloading the Project Report(s) found in their data catalog entries.
