French Experiences with UAV Lidar for Power Line Inspection

RTE, the electricity transmission system operator of France, is in charge of maintenance and repairs for over 100,000km of electricity power lines. When the company started to consider solutions to complement helicopters, it chose Delair to deliver the solution to map and digitize power line corridors: a fixed-wing drone equipped with Lidar. Data from Lidar sensors is now at the core of its vegetation encroachment detection process. Here, RTE UAV pilots share their experiences with aerial Lidar data acquisition technology. RTE manages power line inspection with Lidar drone to detect vegetation encroachment. Its mission is to direct the flow of... (read more)

Leica Geosystems Enhances Construction Collaboration with Launch of BLK3D Web

Leica Geosystems, part of Hexagon, has launched BLK3D Web, an online collaboration workflow that extends the Leica BLK3D imager by enabling users to share 3D measurable images with anyone, anywhere online. The BLK3D device allows users to take precise, 3D measurements directly in the images it creates. Now, with a BLK3D Publisher license, those 3D image files can be easily and securely uploaded to the cloud. Once published, the 3D image files can be viewed and measured with BLK3D Web via a shared link, a simple and powerful tool used across major collaboration platforms today. “BLK3D Web in-picture measurements make...

Portable Lidar Technology Provides Archaeology Students with New Insights

How can modern geospatial technology be used to preserve the past? Archaeology students from Wheaton College in Illinois, USA, have utilized a long-range Lidar sensor during an excavation project in Tel Shimron, Israel, to conduct daily high-resolution scans of the area. The scans gave the students a high-precision record of what they uncovered every day as the basis for further analysis. Velodyne Lidar provided its portable Ultra Puck sensor to enable a new generation of archaeologists to reconstruct life from thousands of years ago. (This article contains a video) Earlier this year, McKenzie Blank, a chemical engineering student at Wheaton... (read more)

The Rotterdam 3D City Model

3D Digital Twin: Urban IT Crossover of Interconnections
If 3D is becoming the new normal in spatial data infrastructures, how can it be used in an urban environment? The Dutch city of Rotterdam, known as home to the largest port in Europe, is preparing for that next step by developing a digital twin of the physical city. The primary aim of ‘Digital City Rotterdam’ is to improve the efficiency of urban planning and management. But at the same time the city council is on the lookout for applications that will help people integrate the digital world into their real one – or will it be the other way around... (read more)

Galileo Satellites to Enable More Efficient Cadastral Land Surveys

Researchers have received a H2020 grant to further improve the availability of the Galileo system and to integrate land surveys in the cadastral workflow. With this new European global navigation satellite system (GNSS), cadastral measurements can be conducted real time in the field. This possibility for on-field boundary determination makes conducting cadastral surveys more efficient. Researcher Edward Verbree explains: “Every system has its own accuracy. For most applications, accuracy to a few metres is perfectly agreeable. For cadastral applications however, every centimetre counts. With this new system, we can easily achieve centimetre accuracy and measure quickly, too. That means the... (read more)

CORS Networks Harnessed for Global Error Mapping

There are more than five billion satnav devices on Earth. Along with smartphones and mobile receivers, this figure includes networks of continuously operating receiver stations (CORS) used to improve accuracy. A European Space Agency-led project will harness these networks to provide an ongoing overview of satnav performance from the global to national and regional scale. “The general assumption is that global navigation satellite system (GNSS) services can always be relied on, which is true 99% of the time,” comments Michael Pattinson of Nottingham Scientific Ltd in the UK, which is developing this new project for ESA. “That’s fine for the...

USGS Releases New Lidar Base Specification

The U.S. Geological Survey National Geospatial Program (NGP) has released a new version of the USGS Lidar Base Specification (LBS) that defines deliverables for nationally consistent Lidar data acquisitions. This update – version 2.1 – of the Lidar Base Specification better aligns the specification with the Lidar data workflow in the USGS NGP, streamlines the data publishing workflow, clarifies language and addresses Federal requirements to use non-proprietary data formats.     3D Elevation Program The USGS Lidar Base Specification provides a common base specification for all Lidar data acquired for the 3D Elevation Program (3DEP) component of The National Map. The goal of the... (read more)

InSAR Satellite Technology Data Fills Niche for Forest Inventory

Remote sensing is a great way to learn more about our forests and manage them accordingly. Scion, a New Zealand government-owned research institute, is exploring new information-capture methods such as synthetic aperture radar (SAR). A recent study found that, while Lidar is still much more precise for predicting forest attributes, interferometric synthetic aperture radar (InSAR) has several other benefits to consider. Remote sensing involves recording data about an object, without making contact with the object. Interferometric SAR (InSAR) satellite technology is one method that has been used to perform forest inventory overseas, but a study that was conducted recently is... (read more)
