This project contains 50cm LAS tiles and 1m DEM tiles for areas in Cooke, Montague, Wise, and Grayson County Texas. The project AOI was defined by new quarter-quarter-quadrangle, NQQQ, tiles. The outside tiles were buffered by 300m on all sides and the interior tiles were buffered by 50m on all sides. The project design of the Lidar data acquisition was developed to support a nominal post spacing of 4pts /meter.

Data was acquired by Surdex Inc. and The Atlantic Group under sub-contract to Surdex from May 20 through August 4th , 2010. Lidar data collection was performed with a Cessna 375 aircraft, utilizing a Leica ALS50-II MPiA sensor and a Cessna 210 aircraft, utilizing a Optech Sensor collecting multiple return x, y, and z data as well as intensity data. Lidar data was processed to achieve a bare ground surface.

This dataset was acquired through the High Priority Imagery and Data Sets (HPIDS) contract. The contract was created in 2009 to maximize spending power by coordinating geospatial data purchases to share costs and to ensure that acquired data meet high standards of quality. The successor to HPIDS is the StratMap contract, established in 2015.
