USGS Study Validates Use of Lidar-Derived Models for Gravity Data Reduction
August 05, 2025
WASHINGTON, Aug. 5 (TNSLrpt) -- A new U.S. Geological Survey (USGS) study, "The Feasibility of Using Lidar-Derived Digital Elevation Models for Gravity Data Reduction," explores a more cost-effective and efficient way to process gravity data. Traditionally, gravity data reduction relies on expensive, submeter-accurate differential global navigation satellite system (dGNSS) equipment to acquire elevation measurements. This report, however, investigates whether publicly available lidar-d . . .
