UAVs Help Monitor Lake Winnipeg Ice Hazards

Fixed-wing drones from senseFly have been used to track and monitor the formation of lake ice hazards on Lake Winnipeg by NextGen Environment Research, a Canadian company based in Winnipeg. The project, conducted as part of the Canadian Space Agencies Earth Observation Applications Development Program (EODAP), aimed to identify and monitor the levels of lake ice and detect cracks and pressure ridges to raise awareness among local communities and first responders about the risks of lake ice travel. With studies projecting a reduction in lake ice mass over the coming years, ice safety is becoming a critical consideration for many... (read more)

European Association of Aerial Surveying Industries Appoints Secretary-General

The European Association of Aerial Surveying Industries (EAASI) has appointed Marcos Martínez-Fernández as secretary-general. EAASI was officially launched last year to bring together companies involved in the generation of geographic data from manned aerial platforms, and it has grown rapidly ever since. This appoinmtent represents the next stage in the association’s future as Marcos Martínez-Fernández will manage both day-to-day and strategic business operations. “The aerial imaging market is rapidly evolving and dynamically responding to the challenges being faced by business, government and the third sector as a result of the global pandemic,” commented Simon Musäus, president of EAASI. “As a relatively...

Trimble Adds New Innovation to Flagship GNSS Solution

Trimble has introduced the Trimble R12i GNSS receiver, the latest addition to its Global Navigation Satellite System (GNSS) portfolio. The Trimble R12i incorporates Inertial Measurement Unit (IMU)-based tilt compensation using Trimble TIP technology, which enables points to be measured or staked out while the survey rod is tilted. This empowers land surveyors to focus on the job at hand and complete work faster and more accurately.  The IMU-based tilt compensation capability of the Trimble R12i builds on Trimble’s highly regarded ProPoint GNSS positioning engine which, according to the company, delivers more than 30% better performance in challenging environments compared to...

Full Frontal Mapping in 3D

Cliff surveys are traditionally performed with fixed-wing aircraft that collect nadir photos. However, one particular California bluff required the cliff’s face to be surveyed for an erosion study. A photogrammetry company used the opportunity to test the viability of accurately triangulating oblique images and mapping them in 3D stereo. The company not only met tight data specifications, but also developed a new technique for cliff-face surveys. Photogrammetry specialist Robert Lafica and his company, Central Coast Aerial Mapping, have been producing detailed 3D stereo-based topographic maps, orthophotos and orthomosaics and surface models since 1977. Although he has performed many traditional cliff... (read more)

Newly Launched Leica GNSS RTK Rover Equipped with Visual Positioning

Leica Geosystems, part of Hexagon, has unveiled the Leica GS18 I, a versatile, GNSS RTK rover with visual positioning. The GS18 I allows users to capture points of interest from a distance and measure points from the images in the field or in the office. Visual positioning technology – sensor fusion combining GNSS, IMU and a camera – allows users to reach previously inaccessible or obstructed points safely and efficiently. Visual positioning is based on photogrammetric technology with near real-time data processing, allowing surveyors to check the quality of their data while on site. “The GS18 I and the workflow in...

An App Transforms Land Administration

GIS Is Innovating How Land Data Is Collected and Managed
'What if we put fit-for-purpose land administration thinking into a single app?' wonders Brent Jones, the man who oversees Esri's worldwide strategic planning, business development and marketing activities for land records, land surveying and land administration. 'How would we do that?' When Brent Jones started his career as a surveyor, data collection involved hauling around heavy tools such as total stations, tripods and range poles. Data had to be manually recorded in weatherproof field books using a number-four lead mechanical pencil. Then came the advent of the Global Positioning System (GPS), experimental satellites, receivers powered by car batteries and PhD students to help... (read more)

Phase One and Acecore Integrate Camera and Drone Technologies

Phase One, a leading provider of medium and large-format metric cameras and imaging solutions for aerial applications, has signed an agreement with Acecore Technologies, a developer and manufacturer of unmanned aerial vehicles (UAVs) for cinema and creative, industrial and security markets. Together, these companies’ high-end products are opening new opportunities in drone-based high-accuracy mapping and inspection markets. “The integration of the Phase One iXM camera with the Acecore drone allows full control from the ground, preventing unexpected errors that would require repeated flights and therefore saves precious time,” said Koen Vrints, professional UAV surveyor at Koen Vrints BVBA. Phase One... (read more)

Multibeam Lidar for Mobile Mapping Systems

Features and Productivity
In mobile mapping, geospatial data is acquired by one or more cameras and/or one or more Lidar sensors mounted on a vehicle that moves over land, through water or through the air. The distribution of Lidar beams over the scene may be realized by a spinning mirror or by a solid-state device. Multiple beams may be emitted simultaneously, and single or multiple returns may be captured. This article discusses the features and productivity of various multibeam Lidar sensors suited for mobile mapping. In the case of the selected Lidar sensors, the mechanisms for distributing emitted beams over the scene are... (read more)

Image Anonymization for Mobile Mapping

Achieving Legal Compliance of Mobile Mapping by Anonymizing Images
Large amounts of personal data, such as faces and number plates, are collected during mobile mapping. Receiving consent from individuals for large-scale data collection is not feasible but is required by law in certain countries. Anonymizing images not only eliminates the need for consent but also increases trust in companies who conduct mobile mapping. Privacy concerns in mobile mapping go back to 2010, when the Belgian Privacy Commission published the “Recommendation on Mobile Mapping”.  The scope of the recommendation covered not only applications such as Google Street View but also other types of mobile mapping such as mapping by public...
