LiDAR

LiDAR – Light Detection And Ranging – is a proven technology for collecting very high accuracy elevation data, both for bare earth models (DTMs – Digital Terrain Models) and first-return models (DSMs – Digital Surface Models). VeriDaaS utilizes a proprietary LiDAR system configuration that facilitates collection of unprecedented accuracy and point density for large area collections.
