The project area is 322 tiles covering approximately 1285 square miles in the Ft. Worth region of Texas. The original 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 1.0 meter.

Fugro EarthData, Inc. acquisition acquired 101 flights lines in 13 lifts from March 15, 2009 through March 29, 2009. Lidar data collection was performed with a Piper Navajo aircraft, utilizing a Leica ALS50-II MPiA sensor, collecting multiple return x, y, and z data as well as intensity data. Lidar data was processed to achieve a bare ground surface.

The purpose of this project is to collect and deliver topographic elevation point data derived from multiple return light detection and ranging (Lidar) measurements for Ft. Worth Region in Texas. The elevation data will be used as base data for Texas flood plain mapping.

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.
