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…

Blog Series: Parameters of Airborne LiDAR Survey
Follow this growing series of blog articles that breaks down the key parameters behind airborne LiDAR and explore how they connect and influence each other, shaping every survey.

Surveying Altitude
Working in survey projects, I learned quickly that survey altitude is more than a planning detail. It drives both cost and success. This article explains why it matters and how it shapes other LiDAR parameters.

Fundamentals about aircraft speed you need to know
Flying speed affects project efficiency, yet external conditions can sometimes require adjustments to keep the work on track.

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.

Point Density and Point Spacing
Point density feels obvious, yet the way LiDAR samples objects shapes what your data can support. Subtle gaps or clusters can change how you read the scene, or mean that smaller objects go unnoticed altogether.

What is range gate and how do LiDAR sensor manufacturer deal with it?
LiDAR range gates limit how far a sensor can measure before pulses overlap, creating ambiguities at high pulse rates and shaping how modern systems handle long‑distance returns.

Four essential LiDAR parameters
LiDAR surveys rely on four simple parameters, yet each one shapes how efficiently you capture the world. Together they determine what your data will actually be useful for.

An Introduction to LiDAR
LiDAR has grown rapidly, and I’ve seen how powerful it becomes once you understand how it works and where its limitations lie. In this article I break down those fundamentals.
