This data has been acquired and developed by the Texas Natural Resources Information System (TNRIS) for collection and delivery of topographic elevation point data derived from multiple return light detection and ranging (Lidar) measurements for the 2256 sq. mile project area encompassing Bandera and Lampasas Counties, Texas. Fugro EarthData, Inc. acquired 305 flight lines in 36 lifts from December 18, 2013 to January 25, 2014. Lidar data collection was performed with a Cessna 310 twin engine aircraft, utilizing a Riegl LMS-Q680i Lidar sensor; collecting multiple return x, y, and z as well as intensity data. The classified Lidar point cloud data are delivered in LAS 1.2 format: 1, unclassified, 2, bare-earth ground, 3, low vegetation, 4, medium vegetation, 5, high vegetation, 6, buildings, 7, low points(noise), 9, water, 13, bridges, and 14, culverts. Specialized in-house and commercial software processes the native Lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. The horizontal datum for the data is in UTM 14N Coordinates, NAD83(2011) in meters and the vertical datum is the North American Vertical Datum of 1988 (NAVD88) in meters using GEIOD12A.

The data acquired will become part of an ongoing data collection by the State of Texas to support mapping and modeling of flood plains, hydrography, and terrain.The data are intended to exceed requirements for Federal Emergency Management Agency (FEMA) specifications for Floodplain Mapping as well as serve as an input to the U.S. Geological Survey refinements to the National Elevation Dataset. The project consists of high accuracy classified Lidar data in LAS format as well as raster digital elevation models and intensity images.

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.
