Doubling Airborne Lidar Data Acquisition

Leica Geosystems' Point Density Multiplier technology for airborne Lidar allows the use of a single laser and scanning mechanism to provide over double the data collection productivity of previous systems. This technology will be incorporated into Leica Geosystems' ALS series airborne Lidar Systems.   According to Ron Roth, Product Manager for Airborne Lidar at Leica Geosystems' Airborne Sensors Business Unit, the market constantly demands higher productivity from airborne sensing systems to reduce the equipment and labor costs associated with data collection. The measurement rate of 500kHz gives the industry-leading data acquisition productivity that Leica's customers desire, without the complexity of... (read more)

Lidar/camera Flight Management System

A new flight management system, Optech FMS, is available for the Optech line of ALTM airborne laser terrain mappers and digital mapping cameras. Based on a real-time point cloud generator, Optech FMS is a huge leap forward in data collection efficiency and in-air confidence. By computing real-time XYZI geocoded points, Optech FMS can determine true coverage in the air irrespective of terrain conditions without the time-consuming stage of on-the-ground post-processing. Optech FMS has the unique ability to store real-time point clouds as LAS files, giving users the option to deliver high-resolution topographic data immediately upon landing. Increased real-time positioning accuracy... (read more)

The Democratization of Lidar Data

The geospatial technology of Lidar is still relatively unknown to many members of the general public, but it looks as if this is about to change, according to Wim van Wegen in his latest column. The automotive industry is making rapid advancements in the use of Lidar to support autonomous driving, for instance, so the term ‘Lidar’ may soon become as familiar as the likes of ‘radar’ or ‘sonar’. Lidar data offers endless possibilities, especially now there is a growing trend to make it publicly accessible. The Current Dutch Elevation (Actueel Hoogtebestand Nederland/AHN) is a good example of this. Helicopters... (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 capturing the near-shore land and sea surface. Bathymetric Lidar is the most effective and cost-efficient technology to capture both the land and seafloor simultaneously to provide a continuous, detailed 3D elevation model along the coastline. Its ability to successfully capture elevation on both sides of the coastline, over areas stretching more than 100km along the coast, has made it the ‘gold standard’ for... (read more)

The Multispectral Journey of Lidar

Adding Channels to Laser Scanners Will Disrupt Lidar-based Target Identification
Optech Titan-3 has ushered in the era of multispectral airborne laser scanning, but multispectral terrestrial laser scanning (TLS) is still only available via research instruments, mostly for ecological vegetation studies. Analysing spectral ratios can reveal much about vegetation status and health, and multi-wavelength Lidar enables this analysis in 3D. However, multispectral Lidar will disrupt many other fields in the future. This article provides some first glimpses of how and why. Four research groups have published 3D TLS point clouds since 2012, and many others have already focused on the multispectral laser return rather than spatial analysis. Multi-wavelength point clouds are... (read more)

Recent Developments in Airborne Lidar

Multispectral Laser Scanning, Single-photon Lidar, Hybrid Sensors and UAVs
The arrival of airborne Lidar, also referred to as airborne laser scanning (ALS), has revolutionized area-wide 3D data acquisition of topography, bathymetry, vegetation, buildings and infrastructure. This article presents an overview of the progress made since then in both sensor and aircraft technology. On top of that, it highlights how ongoing miniaturization has recently enabled the application of Lidar on unmanned aerial vehicles (UAV), resulting in ultra-high-resolution 3D point clouds with centimetre precision. From Single to Multiple Pulses in the Air Current trends include a steady increase of the measurement rate, achievements in full waveform processing, the spread of multispectral... (read more)

Lidar: Quality Assurance and Control

Lidar systems have been widely adopted for the acquisition of dense and accurate topographic data over extensive areas. Collected topographic data can satisfy the needs of several applications, such as environmental monitoring, contour mapping, transportation planning, emergency management, military simulation, ortho-rectification, oil and gas exploration, mining, hydrology, shoreline management, 3D city modelling, and forest mapping. This article presents the author’s suggested road map towards the development of commonly accepted procedures for ensuring and verifying the quality of derived products. Best Practices As in any mapping activity, a set of commonly accepted best practices need to be established to ensure the... (read more)
