LiDAR Data

What is LiDAR?

LiDAR is an acronym for Light Detection and Ranging. Using a suborbital platform with LiDAR instruments such as a laser, scanner, or a GIS receiver, one can examine natural and man-made features found on the surface of the Earth. The return of a thousand laser reflection points paints a representation of the ground’s terrain, making LiDAR technology a valuable tool for terrain analysis.

Available LiDAR dataset dates are from November 2011 to March 2017. This acquisition covers approximately 1,870 square miles and includes all of Bexar County with edge coverage of Bandera, Kendall, Comal, Guadalupe, Wilson, Atascosa, and Medina Counties. SARA collaborates with partners that include the Texas Natural Resource Information Systems (TNIRS)/Texas Water Development Board (TWDB).

LiDAR Request:

To request LiDAR data, please email saragis@sara-tx.org or call SARA GIS and specify what datasets you would like.

SARA GIS uses external hard-drives to transfer LiDAR datasets. LiDAR datasets can exceed 1tb or more in size. It is recommended that you provide an external hard-drive. However, if you do not have an external hard-drive available SARA GIS can provide you with one at the cost of $300.

Please inquire about costs prior to making a request.
