Masthead for Elevation – Lidar

StratMap Elevation – Lidar

Lidar - Light Detection and Ranging, is a remote sensing technique that utilizes light in the form of a rapidly pulsed laser to measure return distances from the Earth captured by a sensor at the source of the pulse. These combined pulse return measurements with additional spatial and temproral data recorded by the acquisition system(airborne or terrestial) produce a three-dimensional(3-D), detailed representation of the shape of the Earth illuminating its surface characteristics.

Lidar goes beyond traditional bare earth digital elevation models (DEMs) by producing point cloud information that can be classified into existing features such as vegetation and man-made structures.

TNRIS Lidar Coverage

TNRIS acquires lidar data through partnerships with other federal and state agencies through the StratMap Contract, which operates through the Texas Department of Information Resources (TxDIR).

Historically, TNRIS acquired data through the now defunct High Priority Imagery and Data Sets (HPIDS) contract.

Lidar coverage varies across the state. Lidar coverage and project details (date, nps, vendor, etc.) can be found on the Lidar Status Map. All details about each dataset in our collection can be found in the supplemental reports for each project.
