LiDAR Elevation Data

ENPLAN has over 800 square miles of high definition LiDAR digital elevation data in stock. The coverage extends over Shasta, Tehama, and Siskiyou County urban regions and beyond. The data was collected via aircraft for us by Sanborn using Optech LiDAR sensor technology. Our LiDAR dataset was used by ESRI in this webpage. It is available for immediate delivery. A map of our current coverage may be seen here. Contact us at or (530) 221-0440 x7123 for details as to coverage for a particular area or site.

Elevations are collected at one-meter horizontal postings with vertical accuracies of ±6 inches at 1 Sigma on flat exposed ground. Precision independent ground survey checks of our bare earth digital elevation model (DEM) data verified this vertical accuracy specification to have been met consistently on such surfaces. The dense and diverse mass-point cloud collected for ENPLAN using LiDAR technology yielded digital elevation data with excellent fidelity and broad utility. Our canopy and hardscape DEMs define vegetation, buildings, and other surface features rising above bare earth. Return intensity files are also available and can be used to produce imagery that differentiates surface textures. Download a copy of the LiDAR Quality Assurance Report.

What is LiDAR?

Airborne Light Detection and Ranging (LiDAR) technology involves a powerful laser, sensor, precision airborne global positioning system (GPS), an inertial measurement unit (IMU) and specialized software. The laser and sensor are operated through a portal on the underside of an aircraft. Laser pulses are emitted very rapidly (100,000+ per second) and the sensor measures both the timing and intensity of returns from strike points on the terrain or other features below. The result is a point cloud from which the primary raw elevation data is extracted. See these links for more details: LiDAR | DEM | TIN Click here to download a copy of our coverage map. How To Buy
