Night-time Mobile Mapping of Road Surface Luminance

Capturing Road Environment Lighting Inventories Using a Luminance-calibrated Mobile Mapping System
Lighting – which is measured in luminance plays a key role in improving road safety. A new measurement system is now being deveoped to evaluate night-time road lighting conditions based on luminance-calibrated 3D point cloud data. This new approach integrates imaging photometry, which is commonly used to measure road lighting, with mobile laser scanning techniques, which are mainly used to measure the 3D geometry of the road environment. There are many interesting potential applications of the resulting georeferenced luminance point cloud. In road traffic, the role of illumination is to improve the visibility of the road and the surrounding environment.... (read more)

Measuring Offshore Wind Farm Performance with Lidar Technology

Offshore wind farms are becoming increasingly larger and their turbines are reaching higher into the sky. New knowledge is needed to understand how wind behaves at these altitudes and the forces it exerts on the rotor blades. ECN part of TNO and partners from science and industry have conducted studies into the reliability of Lidar for measuring wind characteristics. Traditional wind measurements are carried out with the aid of a wind mast to which instruments are attached. ECN part of TNO has a test field in the Wieringermeer, the Netherlands, comprising such wind masts equipped with various measurement and calibration... (read more)

Smart Parking in Megacities

App Based on Mobile Mapping Point Clouds and Imagery
Did you know that you can waste a week or more per year hunting for a parking space in busy cities? Nowadays, smart parking apps offer a much-needed answer to the problem – and mobile mapping point clouds and imagery are core ingredients of the solution. Besides saving time by guiding you straight to an available spot close to your destination, smart parking apps also reduce unnecessary fuel consumption, air pollution and greenhouse gas emissions. One such app is AppyParking by London-based AppyWay. The AppyParking app allows users to see all on-street and off-street parking areas, restrictions and operating hours.... (read more)

The Age of Mobile Mapping

Looking back over the past 30 years, it’s hard to believe just how far we’ve come in such a relatively short space of time. Geomatics students in the mid-1980s were exposed to GPS test satellites, the first GPS receivers and the enormous potential that GPS offered the geomatics community (who had already perfected what could be done with the Transit satellite system). With unprecedented absolute accuracy and an impeccable timing mechanism, GPS clearly offered a quantum leap in geomatics capabilities. Two decades later, Lidar – and in particular mobile terrestrial Lidar – seemed to represent the next quantum leap in... (read more)

Laser Scanning of Damaged Historical Icons

Surveying Technology Is Heading for Maturity
Terrestrial laser scanning is becoming an increasingly preferred surveying technique for the 3D documentation of historical buildings. 3D point clouds provide a wealth of information which advanced 3D mapping software can exploit in a relatively simple way, at least when compared to the tedious surveying techniques of the past. However, effective cooperation between architects and the survey team of experts is necessary in order to get the best out of this geodata acquisition technology. In this article, the authors first provide an overview of equipment based on the size of the site and the surveying aim, and subsequently give four... (read more)

UAV Maps New Zealand Beach to Create Detailed 3D Model

A landslide on Clifton Beach, New Zealand, earlier this year injured two Korean tourists when they were washed out to sea. Following this event, the beach was closed while Hastings District Council undertook a risk assessment. The Surveying Company was contracted to provide data collected by an unmanned aerial vehicle (UAV or 'drone') to assist the council in making public safety decisions regarding access to the Cape. To map the cliff faces they used a combination of RTK GPS and a PPK GPS unit mounted to their UAV. Initially the surveyors concentrated on assessing the main rockfall where the tourists...

RIEGL Announces Investment in New Office and Production Facilities

RIEGL, a manufacturer of Lidar scanners for surveying applications headquartered in Horn, Austria, is investing heavily in the expansion of its production and office space. The continued, worldwide demand for high-performance sensors is allowing the company to grow and expand further. The company, which celebrated its 40th anniversary last year, is now meeting the rapidly increasing international demand for RIEGL laser scanners by expanding its office and production facilities. This summer, construction has started on a new office and production facility at the location of the company's headquarters in Horn, Austria. The new building will house the company's printed circuit... (read more)

Sensor Fusion for Precision Agriculture

Low-cost Lidar Camera System without GNSS
Precision agriculture has considerably benefited from the use of unmanned aerial vehicles, often combined with active ranging sensors like Lidar to gather information from underneath the crops, but existing systems are relatively expensive for the farming sector. In this project, researchers in Canada have used an integrated sensor orientation method for the local referencing of Lidar measurements. Their approach is based on loosely coupled, image-aided inertial navigation in which the pose of the camera replaces the GNSS measurements. The result is a low-cost solution that is useful for capturing topographic data of inaccessible areas as well as in GNSS-denied environments.... (read more)
