Measuring the Efficiency of Aerial Surveys
Aerial surveys are often discussed in terms of accuracy, point density or sensor choice. These factors matter, but they do not determine how long a project takes to complete or what the acquisition will cost. A major contributor to both duration and cost is the amount of flying required to execute the project. Operating an…

LiDAR Footprint Diameter
LiDAR points and pulses seem straightforward, but the returning signal represents far more. It reflects how the pulse interacts with objects within its footprint, and understanding that interaction is key to interpreting your results.
