Airborne Lidar

Since the first commercial airborne Lidar systems appeared on the market in the mid-1990s, it has become one of the main geodata technologies for capturing dense point clouds. GIM International made a selection of the most exciting articles we have published on this topic over the past couple of years, ranging from bathymetric Lidar and photon Lidar to applications like forestry, heritage mapping and wildlife management.

Wildlife Management Using Airborne Lidar

The traditional sampling protocol for quantifying potential nesting habitat for murrelet requires an observer to peer up through the tree crown from the forest floor, a task resulting in data of dubious quality. Two-dimension... (read more)

Technology in Focus: Bathymetric Lidar

With sea level rise and increases in the severity of extreme natural events, there has been a renewed push to further our understanding of the coastal zone. Fundamental to understanding risk in areas of high vulnerability is... (read more)

Bringing Colour to Point Clouds

Until now, most commercially available airborne Lidar systems have operated on one single wavelength, reflecting energy from a pulse which is then used for classification or visualisation. New developments have produced the f... (read more)
