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)

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)

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)

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)

World War Two Tunnels Surveyed with SLAM Technology

Many historical projects have great significance for a location’s cultural heritage, and indeed its people. For the team at Historic England, this is the fundamental concept of their work in order to conserve pieces of the country’s history. That much was evident with the latest project, the Ramsgate Tunnels, a 5km network of underground passageways which were paramount to the safety of local people in Ramsgate, Kent, England.  Once used as an underground narrow gauge railway, built to connect the town and docks to help improve trade links to Europe, the railway soon became a target for enemy bombing. It... (read more)

Correlator3D Used for Determining Financial Assistance after Hurricane Dorian

According to SimActive, a world-leading developer of photogrammetry software, Correlator3D has been used by Air Data Solutions (ADS) in Florida to determine financial assistance following Hurricane Dorian. Aerial imagery was collected before the storm for pre-hurricane assessment and afterwards for damage analysis. A Phase One 100MP aerial camera owned by ADS was flown to gather high-resolution images of the affected areas. The data was then processed by SimActive software to create mosaics of orthophotos. The resulting geospatial data helped government authorities to calculate recovery aid funds. “We have been impressed by the accuracy and speed of Correlator3D to support such... (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)
