From Urban to Rural: Enabling Sustainable Urban Planning and Development Using Satellite Imagery

It is estimated that 55% of the world’s population lives in urban areas.  This number is expected to increase to 68% by 2050. Studies have shown that urbanisation combined with the overall growth of the world’s population could add another 2.5 billion people to urban areas. This growth proposes a challenge for today’s urban planners. A challenge that can be aided, by incorporating Very High Resolution (VHR) optical satellite imagery into their planning. This rapid rate of change challenges urban planners to ensure efficient city infrastructure management whilst minimising the impact on the surrounding environment. Satellite imagery provides urban intelligence... (read more)

GEO Business Postponed until May 2021

Following GEO Business organizer Diversified Communications UK has confirmed that this year’s show has been postponed due to the ongoing coronavirus pandemic. The UK’s largest geospatial event designed for everyone involved in the gathering, storing, processing and delivery of geospatial information will now take place on 19-20 May 2021 at ExCeL London. This week’s announcements also include the new dates for Digital Construction Week (DCW), the UK’s only event dedicated to digital construction, engineering, design, manufacturing and operation, with the show now set to run alongside GEO Business. The magnitude and unprecedented scale of the Covid-19 outbreak and the subsequent... (read more)

CHC Navigation’s GNSS Receivers Reach the Peak of Everest

CHC Navigation’s P5 geodetic GNSS receiver has been used successfully by China's National Geodetic Survey Team and Mountaineer's Team to complete the 2020 Mount Everest Elevation Survey. This extreme GNSS surveying project leveraged the performance, reliability and operability of CHC Navigation’s receivers in very challenging temperature and altitude conditions. This was the first time that a team of Chinese surveyors had climbed the summit of Mount Everest, and was also the first time that BeiDou-based Chinese GNSS receivers had been used to measure the height of Mount Everest. In order to promote research on the Mount Everest elevation and to... (read more)

Integrating UAV-based Lidar and Photogrammetry

Dense 3D Point Cloud Generation with Ultra-high Precision
Recent unmanned aerial vehicle (UAV or ‘drone’) platforms jointly collect imagery and Lidar data. Their combined evaluation potentially generates 3D point clouds at accuracies and resolutions of some millimetres, so far limited to terrestrial data capture. This article outlines a project that integrates photogrammetric bundle block adjustment with direct georeferencing of Lidar point clouds to improve the respective accuracy by an order of magnitude. Further benefits of combined processing result from adding Lidar range measurement to multi-view-stereo (MVS) image matching during the generation of high-precision dense 3D point clouds. The project was aimed at the area-covering monitoring of potential subsidence... (read more)

KlauPPK Usage Leads to Changes in GCP Regulations in Japan

Japan’s Ministry of Land, Infrastructure, Transport and Tourism has rewritten its UAV capture specifications based on results using KlauPPK technology. The guideline for work-type management using aerial photogrammetry (earthwork), which outlines the procedures to be used to perform aerial surveys, has until now specified that surveyors must “set up ground control points every 100m”. When KlauPPK technology is deployed, the use of GCPs is now optional. The tests conducted by GeoLink Japan proved that +/-5cm XYZ accuracy can be achieved without GCPs, as verified with check points. This improves the work efficiency and productivity across sites in Japan including public... (read more)

FIG Working Week - What’s Next?

It is Thursday 14 May 2020, and today should have been the closing day of FIG Working Week in Amsterdam. The programme of today would have been the second General Assembly session and closing ceremony. Also a comprehensive tour, 'Dutch land and water management', was scheduled to take place today. The intention of the tour was to give a unique insight into the Netherlands, with a focus on how water has shaped spatial planning and development in the Netherlands. It should have taken attendees on an exclusive journey using various modes of transport, starting at the historical Fort Vechten and... (read more)

Teledyne Optech Partners with Aerial Surveys International to Provide Extremely Realistic Mapping Solution

Teledyne Optech, a Teledyne Technologies company and global leader in advanced Lidar sensors, has signed an agreement with Aerial Surveys International (ASI) to sell a Galaxy T2000, upgrade its existing Galaxy Prime to a Galaxy T2000 and install both sensors in the productivity-doubling G2 Sensor System.This purchase will enhance ASI’s capabilities through the effective two million points per second PRF of each Galaxy T2000.  Moreover, by combining both sensors on the G2 Sensor System, ASI will bolster its capacity to a true, effective four million points per second that provides extreme point density with one of the highest available efficiencies....

UAS Mapping – Where Is It Heading?

The use of an unmanned aerial system (UAS) – cameras and Lidar sensors mounted on an unmanned aerial vehicle (UAV or ‘drone’) – to acquire geodata for mapping purposes has evolved beyond infancy and is now rapidly maturing. How will UAS mapping evolve in the foreseeable future? To envisage where exactly UAS technology is heading, it is appropriate to start with the big picture before examining the details. So what is the current big picture for unmanned aerial systems? How are they embedded in today’s society? First of all, our planet is confronted with climate change. The most threatening effects...

Ten Years to Go to Achieve the Sustainable Development Goals

Unlocking Valuable Contributions of the FIG Working Week 2020
The countdown begins, only one decade to go to accomplish the Sustainable Development Goals (SDGs). The SDGs are the blueprint to achieve a better and more sustainable future for all and surveying professionals have a key role to play. It is therefore of crucial importance that FIG member organisations and surveyors are aware and prepared on how their work contributes to the achievement of the SDGs and vice versa.  The SDGs were appointed as one of the central themes during the FIG Working Week 2020. Many colleagues from the FIG community shared their experiences at practical and strategic level. In... (read more)
