Alluxa Makes Thin-Film Interference Filters for LIDAR

Alluxa is a world leader in high-performance optical filters and thin-film coatings. In this highly informative white paper Alluxa explains how their high-performance, ultra-narrowband interference filters improve LIDAR signal-to-noise ratios. Arguably the most versatile active remote sensing technique, LIDAR (Light Detection and Ranging) is used across platforms and across disciplines. Long known to be one of the most important technologies […]

Novel LiDAR Data Improves Our Understanding of Tropical Forests

Dr. Kim Calders and his team have just completed 2 months of field work in Australian tropical forests collecting both terrestrial and UAS lidar data to support a novel lidar data fusion methodology. Forest ecosystems contain more biomass than any other ecosystem. However, estimating biomass without cutting down trees is difficult. Traditional methods of estimating aboveground biomass (ABG) are based […]

Electrical Network Asset Position and Condition Data

Data gathering is an essential task in order to understand the health of an electrical network. However, many operators are missing out on the cost efficiencies available through using technology to combine routine asset inspection patrols more effectively. In this interview David Langworth, General Manager at NM Group (part of Trimble Inc.) discusses how combining asset condition with other datasets […]

Drone Lidar Components Present Data Quality Challenges

LiDAR representation by Echo using a Riegl MiniVUX -1UAV.

The use of drone LiDAR requires significant training and expertise especially when using inexpensive systems. (Editor Note – This is a cautionary tale told in the author’s words about the perils of self-proclaimed drone lidar experts.) Training is Needed There are a lot of people with drones who are collecting aerial imagery and becoming self-proclaimed mapping professionals in the process, […]

Underground Infrastructure Mapping with Mobile Lidar and GPR

Leica Pegasus2 Stream for underground infratructure mapping

Governments are beginning to mandate that underground infrastructure mapping be carried out as national policy. Underground infrastructure mapping of utilities and other infrastructure is one of the major challenges in creating a digital twin at the municipal, regional, and national level.  LiDAR reality capture of the above-ground ground features simultaneously with ground penetrating radar (GPR) scans of subsurface infrastructure at […]

Rolling Shutter Effect Important in UAV Photogrammetry

Image of Figure 1

Many are not aware that photographs taken with a UAV are subject to the rolling shutter effect. (Be sure to watch the video at the end for great visual explanation.) The main disadvantage of UAV photogrammetry is that it uses non-metric cameras. These cameras have low-quality movable lenses, a small focal length, and most have a CMOS sensor with an […]
