UAS Applications Are Ubiquitous

Unmanned aerial systems (UASs) include imaging systems and/or airborne Lidar systems on an ever-increasing number of variously sized, remotely piloted fixed-wing or multi-propeller systems – the latter being able to hover and take-off vertically – as well as hybrid systems. In 'GIM International' and other surveying and mapping literature, there have been many articles describing the use of UASs, new developments and precautions that need to be taken to achieve satisfactory results. This article explores how UAS applications have become ubiquitous. (By John Trinder and Yincai Zhou, The University of New South Wales, Australia) In many countries, small UAS operations...

High-end UAVs: A Key Link in the Value Chain

Interview with Michael de Lagarde, CEO, Delair-Tech
Unmanned aerial vehicles (UAVs or ‘drones’) have become an essential tool for land surveyors. The geospatial industry is turning to drones to map the environment, which is also impacting the commercial UAV business. Delair-Tech is a prominent company in the industry and attracted particular attention when it acquired Gatewing from Trimble in 2016. In this interview, 'GIM International' asks Michael de Lagarde, CEO of the France-based company, about the company’s strategy, outlook on the UAV market, cameras, fields of application and much more. You recently announced that 2016 was a record year for Delair-Tech. Does that mean that the professional UAV... (read more)

5G Promotes Prosperity of Low-airspace Economy

Faster and Cheaper Surveying and Monitoring
Based on an assessment of all the geomatics-related trade events in the world, the unmanned aerial vehicle (UAV or ‘drone’) service-provider sector is growing faster than any other. Companies in that sector are particularly interested in the evolution of 5G because it can boost their quality of service and innovation. In turn, the regulations will mandate the ability to transmit real-time hyper-local geodata between local authorities and drones used in urban areas. Low-airspace services must not only be very efficient, but also safe. 'GIM International' spoke to Aleksandar Aydemirski, 5G principal engineer and drone specialist at Huawei in Germany, to...

Northern Survey Flights: Subdecimetre Accuracy in Arctic Canada

Achieving Subdecimetre Accuracy in Arctic Canada
To increase capacity at Pangnirtung Airport, situated in a remote mountainous region of northern Canada, one solution could be to relocate the airport to one of two nearby sites. This article provides insight into how unmanned aerial systems were used in a preliminary engineering survey of both sites. The project achieved an accuracy of less than 10cm, despite the challenges including GNSS signal interference and difficult, rocky, rugged terrain. Even for experienced pilots, landing an aeroplane at Pangnirtung Airport on the remote Baffin Island in Canada’s Nunavut province is at best a challenge; at worst, it is impossible. The airport...

Bridging the Gap between Aerial Imaging and Terrestrial Data Capture

The Challenges of Drone Use in Facade Mapping
There have been rapid advancements in unmanned aerial systems over recent years, yet there is widespread consensus that we have still only seen a fraction of how unmanned aerial vehicles (UAVs or ‘drones’) could ultimately improve efficiency for geospatial professionals and their customers. To get a glimpse of the future, 'GIM International' spoke to Mark Nicolai, co-founder of industry start-up Aeroscan. Here, he shares his vision of how drones could form the missing link between aerial imaging and terrestrial data capture. According to independent research by the likes of PwC and Goldman Sachs, the construction industry tops the list in... (read more)
