In 2015, the North Central Texas Council of Governments facilitated the cooperative purchase of 0.5-Meter LiDAR (4PPM) for 2,404 square miles of the NCTCOG region.
The contractor for this project was Woolpert. LiDAR data were collected during two timeframes, January-March 2015 (leaf-off) for the Metroplex portion of the flight and Summer 2015 for the outer county areas (assessing lake levels) and are available for purchase via DFWMaps Marketplace according to the following price schedule.
The LiDAR data are sold in 3,000' x 2,000' tiles, or 0.215 square miles. Sample files and a shapefile of the tile structure may be downloaded below.
