The Texas Central LiDAR Project covers San Antonio and La Grange.  Data is provided and managed by the USGS.  Texas LiDAR data can be accessed on-demand in Equator.

The Texas Central LiDAR Project was completed between January 20, 2017 and March 22, 2017.  There were various stakeholders involved in this project including the Texas Water Development Board (TWDB), Texas Natural resources Information System (TNRIS), Williamson County, United States Fish and Wildlife Service (USFWS), City of Austin (COA) and the San Antonio River Authority (SARA).

The total area covered by the LiDAR survey was 6,522 square miles, which included both San Antonio and La Grange.  The survey was completed by Fugro. USGS Lidar Base Specification 1.2 was followed for this project, and a quality level of 2 was requested.  

Following the completion of the LIDAR survey, AECOM was retained to perform quality assurance and quality control (QA/QC) for the project.  Their complete findings are summarized in this report.  A summary of tested non-vegetated vertical accuracy (NVA) and vegetated vertical accuracy (VVA) at a 95% confidence level is included in the table below.

The counties covered, or partially covered, as part of the Texas Central acquisition project include:
