Lidar Elevation Data

galaxy_1Surdex has captured and delivered lidar data since the early 2000s. We have completed projects for the U.S. Geological Survey (USGS), U.S. Army Corp of Engineers (USACE), oil and gas companies, state departments of transportation and all levels of government. Surdex has been awarded three consecutive Indefinite Delivery Indefinite Quantity (IDIQ) five-year contracts with the USACE – St. Louis District.

Surdex owns three Optech Galaxy Prime lidar sensors, among the most advanced and efficient sensors available today. They use innovative lidar technology enhancements and incorporated flight and calibration software for significantly increased sensor performance, collection efficiency, improved data quality, and a simplified collection process.

SensorPhaseOneFor efficiency of acquisition, Surdex has a proven solution to provide simultaneous elevation and image data collection. Surdex’s Galaxy Prime lidar systems can be paired with our Phase One digital frame camera systems, with both sets of data collected simultaneously. The dual-sensor configuration reduces flight time, ensures the ground conditions match between the datasets and improves the spatial match of the imagery and lidar data. During post-processing the GNSS+INS trajectory solution is used to process data from both sensors.
