Students Help to Put Vulnerable Countries on the Map

The Friends of Médecins Sans Frontières society at Imperial hosted a 'mapathon' to help to improve maps of vulnerable countries. Over 70 members of the public and students came to Imperial College London to attend the student-run mapathon, which tasked participants with making online map improvements to help disaster risk assessment and energy management in vulnerable parts of the world. Accurate maps can also help with vaccination control, as well as wider healthcare and aid delivery.  The Imperial event was organised by Imperial’s Friends of Médecins Sans Frontières (MSF) student society. Kishan Patel, a fourth-year medical student and vice-president of the... (read more)

Using PPP Corrections in Precise Real-time Applications

Minding the Gaps
Satellite-delivered GNSS correction services can be used in many real-time applications where real-time kinematic (RTK) and virtual reference stations (VRS) are not available. In areas without regular communication systems, satellite-broadcast PPP corrections can deliver centimetre-level positioning worldwide in real time. While geospatial professionals who use RTK and VRS enjoy reliable, cost-effective performance in a broad array of tasks, there are many instances where conditions conspire to make working in real time difficult or even impossible. For example, hilly terrain may block radio signals from an RTK base station, while inconsistent cellular coverage can disrupt or cut off communications with the... (read more)

How Drones Contribute to Mapping Iceland's Disappearing Glaciers

A new 3D process which involves old aerial photos and modern-day drone photography has shed light on accelerated ice loss from some of Iceland's largest glaciers. Dr Kieran Baxter from the University of Dundee has created composite images that compare views from 1980s aerial surveys to modern day photos captured with the help of state-of-the-art technology. This revolutionary technique has allowed Dr Baxter to document the dramatic ice-loss on a group of outlet glaciers on the south side of Vatnajökull, one of the largest ice caps in Europe. Aerial mapping photographs taken by the National Land Survey of Iceland were... (read more)

Smart Parking in Megacities

App Based on Mobile Mapping Point Clouds and Imagery
Motorists who regularly drive around busy megacities such as London can waste a week or more per year hunting for a parking space. The quest for somewhere to park burns fuel unnecessarily, pollutes the air with particulate matter and increases greenhouse gas emissions. The smart parking app – based on mobile mapping technology – offers welcome relief for seekers of parking spaces while also helping to preserve the environment. One such app by London-based AppyWay, named AppyParking, is available for free download for iPhone and Android devices. The AppyParking app allows users to see all on-street and off-street parking areas,... (read more)

Trimble Launches New R12 GNSS Receiver

Trimble has introduced the Trimble R12 GNSS receiver, a high-performance global navigation satellite system (GNSS) surveying solution. Powered by an all new real-time kinematic (RTK) and Trimble RTX positioning engine, it features innovative Trimble ProPoint GNSS technology that empowers land surveyors to quickly measure more points in more places than ever before. Surveyors who work in challenging GNSS environments can use the Trimble R12 receiver to help reduce both the time in the field and the need for conventional techniques such as using a total station. The new Trimble ProPoint GNSS technology allows for flexible signal management, which helps mitigate the effects of... (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)

ESA Employs CORS Networks for Global Error Mapping

As of today, there are more than five billion satnav devices on Earth. Along with smartphones and mobile receivers, this figure includes networks of fixed receiver stations, used to improve accuracy. An ESA-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 in the UK, which is developing this new project for the European Space Agency (ESA). "That’s fine... (read more)
