The San Antonio River Authority is proud to offer LIDAR data at no cost to the requestor. LIDAR, or Light Detection and Ranging, utilizes a suborbital platform with various instruments (i.e. laser, scanner, GIS receiver, etc.) to capture a visual representation of natural and man-made features found on the surface of the Earth. The output return of thousands of laser reflection points paints a vivid depiction of the physical features distributed across the study area, making LIDAR technology a valuable tool for terrain analysis.
Below are two methods to gain access to our LIDAR data:
- Visit our open data LIDAR portal to view the following datasets currently available for download:
- Bexar County
- - 2010 Contours
- - 2017 Contours
- Wilson County
- Karnes County
- Goliad County
Submit a data request below and provide the GIS Team with an external hard drive that can store the requested dataset(s). Because most LIDAR datasets are 1TB or larger in size, please provide a hard drive of 2TB or larger.
When requesting specific LIDAR dataset, please provide the GIS Team with the particular types of LIDAR data (i.e. contours, DEMs, raw files, etc.) that you would like to receive.
