Topographical LiDAR

LiDAR technology captures the world in 3D, turning landscapes, cities, and forests into highly detailed digital maps. With this technology, we can see terrain, vegetation, and infrastructure like never before, providing actionable insights for smarter planning, design, and decision-making.

How LiDAR Works

LiDAR (Light Detection and Ranging) uses laser pulses to measure distances with extraordinary precision. These pulses are emitted from airborne or ground-based sensors and reflected back from the surfaces they encounter. By analyzing these reflections, advanced processing software assembles millions of points into a three-dimensional representation of the environment - a point cloud.

The density of points can vary depending on flight altitude and sensor settings, ranging from a single point per square meter to over 100 points. This high level of detail allows for accurate and reliable mapping, even in areas covered by dense vegetation.

Airborne LiDAR provides exceptional coverage and detail of terrain that is difficult to survey using traditional methods. By penetrating gaps in vegetation, it can generate precise models of the ground surface. The resulting point clouds can be further processed to classify and separate different objects, including:

• Terrain surfaces

• Vegetation

• Buildings

• Power lines

This makes LiDAR a versatile tool for a wide range of applications, from environmental monitoring to urban planning and infrastructure design.
