The Future of Lidar is Critical to the Future of Our World

What will be the future of Lidar? To quote Abraham Lincoln: “The most reliable way to predict the future is to create it”. So what is currently being created in the geospatial market? This article focuses on Lidar in relation to a number of relevant themes: Lidar technology, open data and artificial intelligence/machine learning (AI/ML). Lidar technology is developing rapidly, as illustrated by the number of start-up companies to serve the autonomous market which feature traditional mechanical scanning devices, tiny-chip solid-state Lidar units and the emerging FMCW Lidar. The fact that Apple has announced an iPad with Lidar indicates this technology’s... (read more)

Bringing a New Level of Intelligence to UAVs

GIM International Interviews Jan Stumpf, CEO, Ascending Technologies
Although new UAV companies are taking off all the time, Ascending Technologies has been part of the geomatics world for several years and has already become a familiar face in the industry. In 2009 its renowned AscTec Falcon 8 went into serial production, setting a new standard for professional aerial imaging in the areas of aerial photography, industrial inspections and of course surveying. At GIM International we considered our 3rd UAS Special the ideal occasion to talk to Jan Stumpf, one of the founders of the German technology start-up. Mr Stumpf, on your website your company is described as a... (read more)

UAVs Revolutionise Land Administration

Fit-for-purpose Mapping
In 2014, a joint publication by the World Bank and the International Federation of Surveyors (FIG) entitled 'Fit-for-Purpose Land Administration' noted that 75 percent of the world’s population do not have access to formal systems to register and safeguard their land rights and, therefore, there is an urgent need to build affordable and sustainable systems to identify the way land is occupied and used. The emergence of small, affordable unmanned aerial system (UAS) technology and recent advances in highly automated mapping techniques offer a new tool and methodology for producing faster and cheaper spatial data that can benefit land administration...

UAS Lidar for Ecological Restoration of Wetlands

How New Technologies Are Helping to Preserve the Environment
Wetlands are essential ecosystems which provide numerous benefits to society as a whole. But their functionality strongly depends on the hydrology and topography of the watershed, thus creating the need for monitoring. The use of terrestrial topographical survey methods can be a challenging task in wetlands, however. Flooded areas, muddy terrain and low vegetation can substantially slow down or even prevent the movement of surveyors, while tall vegetation can obstruct GPS reception. As this article outlines, advanced technologies such as airborne or UAS Lidar offer interesting alternatives for surveying the hydrology and topography of wetlands. Wetlands are ecosystems where water... (read more)

Towards Smaller and Smarter Solutions

Reflections on Intergeo 2019
Intergeo is a leading annual industry showcase where geospatial professionals gain an excellent impression of the latest innovations. On the brink of a new decade, Intergeo 2019 gave us a glimpse of the future. In general, we can conclude that solutions are getting smaller and smarter, and there are some new kids on the block. But with all the buzz around machine learning and artificial intelligence, how can we cut through the hype to get the most out of the rapidly advancing technology? One thing was crystal clear at this year’s Intergeo: the unmanned aerial vehicle (UAV or ‘drone’) has... (read more)

UAVs: Where to Focus on Next?

New Technologies Require New Knowledge and Regulations
In June 2018, RSPSoc's 'Photogrammetric Record' publication devoted 11 pages to determining which term they would use for drones. They ultimately decided on ‘unmanned aircraft system’ or ‘UAS’. However, the mere fact that this required 11 pages goes some way towards highlighting the complexity and cross-discipline potential that drones bring, not only to the remote sensing industry but also for multiple other uses, writes Peter Kinghan. Over the past decade we have seen a number of drone uses come through the tried-and-tested period, resulting in unmanned aerial vehicles (UAVs) becoming a proven technology for a range of industries and professions,...

Recent Advances in Geodata Acquisition Technologies

No Information without Data
Today’s geodata acquisition technologies combine microprocessors, computer power, solid state drives, complementary metal-oxide-semiconductor (CMOS) sensors, miniaturisation and many more developments. But demand is just as important as supply, and demand is rapidly increasing in our changing world. Read on for details of recent advances in geodata acquisition technologies. In today's world, we are seeing metropolises cluster to form megalopolises, climate change threatens humans, land and livestock in low-lying areas such as river deltas and valleys, and massively populated areas are prone to earthquakes and landslides. All of these factors are increasing the demand for geodata acquisition. This article starts with total stations, continues... (read more)
