Lidar
Lidar, or Light Detection and Ranging surveying, is a measuring system that uses light. It is widely used in archaeology, forestry, geography, geology, seismology, remote sensing and contour mapping and is spreading to many more geomatics applications. The market for laser scanning is growing strongly as more efficient and cost-effective ways of processing Lidar data create new possibilities in a range of different fields, including construction and engineering, industrial facilities, topographical applications and cultural heritage. GIM International is closely monitoring these developments and will continually keep you updated on the innovations in this ever-changing market through this dedicated Lidar page. Whether you are interested in latest articles and news on Lidar in general or in specific topics like Lidar Survey and Mobile Lidar, you will find it here!
Lidar Data Capture: Where Are We Now?
Lidar provides an excellent way for mapping applications such as distribution utility services, as-built surveys of mines and roads, vegetation risk management and forestry services. In this article T...
Paving the Way for Self-driving Cars
Since Karl Benz was granted a patent for his first internal combustion engine in 1879, the automotive industry has changed substantially. Or has it? The main principle remains the same: cars still hav...
The Evolution of Lidar
Current airborne Lidar systems, such as the Leica ALS series, capture one million points per second. Increasing the pulse repetition rate is the best way to achieve dense point clouds at lower costs, ...
Pushing Lidar to the Limits
Airborne bathymetric Lidar is an ideal tool to study underwater features in the usually rather clear waters along the coast of Australia. Due to the remoteness of many of the continent’s coastlines,...
The Fierce Rise of Airborne Lidar
Today, automatic matching of overlapping aerial imagery and airborne Lidar are the main geodata technologies for capturing dense point clouds of the Earth’s surface. The sampled points are used for ...
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 ...
Lidar Survey over Ancient Maya City
The ancient Maya site of Copan, Honduras, was captured during an airborne Lidar survey in May 2013. The resulting products are accessible through 2D and 3D WebGIS tools and enable archaeologists to co...
Lidar, Imagery and InSAR for Digital Forestry
Benoît St-Onge is a professor at the University of Quebec in Montreal, Canada. He works at the Department of Geography with a major research interest in 3D remote sensing for forest analysis. 'GIM In...
Lidar-driven Innovation
The first laser was built in 1960 by Maiman, two years after Miller and LaFlamme introduced the digital terrain model (DTM) in the context of civil engineering purposes in 1958. Probably, none of them...
