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)

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)

Airbus and Sobloo Announce Finalists of Multi-Data Challenge within Copernicus Masters 2019

Airbus has unveiled the names of the three finalists for the 'Airbus - Sobloo Multi-Data Challenge' organised as part of the Copernicus Masters 2019. This international competition recognizes pioneering solutions, concepts and ideas for industry and society based on Earth observation data. Annually, different prize categories reward innovative candidates, in the fields of deep learning, big data analytics, smart mobility and industry 4.0. The 'Airbus - Sobloo Multi-Data Challenge' was especially looking for value-added solutions that use both Copernicus and Airbus Earth observation data. These services should also provide insight and have impact on areas like Natural Resources Consumption, Agriculture,... (read more)

Geospatial Data as a Core Instrument to Transform a Country

Interview with Borko Drašković, General Director of the Republic Geodetic Authority (RGA), Serbia
After several turbulent decades, the Republic of Serbia is working towards a brighter future, including by radically transforming its geospatial information infrastructure. In fact, the country has received recognition for its reforms in the process of digitalization and economic development of the state. This confirms the role of geospatial data as a fundamental 21st-century resource with considerable potential for economic and social development of state and society. In this interview with Borko Drašković, general director of the Republic Geodetic Authority (RGA), 'GIM International' takes a closer look at the achievements in Serbia, which can serve as an example for other...

InSAR Used to Create Ground Stability Maps

Zooming on a Groundbreaking Revolution
Satellite radar interferometry (InSAR) is a technique that can measure millimetre-scale movement of the ground from space. It does this by comparing the return echoes, and thus the signal-path length, from two or more radar images taken over the same place, over time. Modern InSAR is now used by a range of industries concerned with ground or structural stability, from building development and control, to oil and gas production, to mining, to road and rail management. This article explains some key aspects of InSAR technology, including its innovative use to produce ground stability maps. Phase Shifters InSAR is based upon... (read more)

Big Data, Rising Tides

How Advances in Free Remote Sensing Technology Can Help Cities to Prepare for Climate Change
Combining big data with satellite imagery can help cities such as Kampala, the capital of Uganda, to better prepare for natural disasters such as urban flooding and make more informed investment decisions. In view of the increased vulnerability of cities to climate and disaster risks, accurate and up-to-date geospatial data is fundamental for a more resilient urban planning approach. Publicly available geospatial datasets are increasingly becoming the foundation stone for more informed urban planning decision-making and better investment prioritization. Today, satellite data can help cities to better prepare for natural disasters such as urban flooding and make more informed investment... (read more)

Uruguay Updates National Imagery to Support Sustainable Development

The last complete aerial photography collection effort in Uruguay was conducted in 1966‒1967 to produce a national dataset at 1:50,000 scale. Only parts of the country have been captured since that time. In 2015, recognizing the multiple benefits of updated cartographic information to support future development, the Uruguay government, through the IDEUy (Infraestructura de datos espaciales de Uruguay), initiated a project to map the nation. Based on a thorough evaluation of the alternatives, including aerial photography, Lidar and satellite imagery, the IDEUy chose aerial digital cameras as the best technology to update the Uruguayan geographic dataset. (this article is brought... (read more)

Sensors, Satellites and Science: the Power of Geoinformation

Review of ISPRS Geospatial Week 2019
Every two years, the photogrammetry and remote sensing community gathers at the ISPRS Geospatial Week. The event comprises a combination of workshops organized by various ISPRS Working Groups and other stakeholders involved in the geospatial profession. The 2019 edition, which was held from 10-14 June in Enschede, situated in the eastern part of the Netherlands, proved to be a true geospatial hub bringing together a wide range of geomatics-related activities and applications. Creating a better, safer world – that broadly sums up the objective of the ISPRS Geospatial Week participants. With projects covering innovations for land tenure, an efficient method... (read more)
