Balance and Buzz - GEO Business 2018

Without a doubt, this year’s GEO Business was the biggest and best yet. The heart of the event is the exhibition and this year there were 203 exhibitors from 25 countries. It even overflowed onto the balcony above the main hall. The one day conference featured some high profile speakers, there were 19 seminars covering a wide range of topics, and getting on for 100 exhibitor workshops. The workshops enabled potential customers to hear more detail on exhibitors’ products, but with these the objective is ultimately to sell. For those who were looking for something more independent there were the... (read more)

Geospatial Data in Support of 3D Cadastre

Zooming in on Recent Technical Developments
The urbanization trend is leading to an increasing number of people living in cities, thus also placing new demands on cadastral registration. To be able to register the complex infrastructures and built-up areas properly, the cadastre will need to consider the third spatial dimension. The 3D cadastre is based on 3D parcels (spatial units) which are single volumes (or multiple volumes) of space. Although the technology offers numerous possibilities for implementation of the 3D cadastre, there are still some open issues, as this article explains. We live in a three-dimensional world. Over the past decades, there have been an increasing... (read more)

Who Wants to be a Surveyor?

GW Technical Editor Richard Groom presents a personal view, with contributions from others, of issues surrounding the promotion, education and training of surveyors. A particular problem he identifies for the profession is that of the part-time surveyor. Thanks to technology, we are now able to survey more detail, faster and more cheaply than ever before. The surveying profession has expanded well beyond its origins in ‘Land’ to encompass ‘Geospatial’ and ‘Spatial’. If it’s physical we can measure it in 2D, 3D, 4D and more. It’s an exciting world, above and below water, made even more stimulating by our ability to... (read more)

3D Documentation of the Forth Bridge

The iconic railway bridge and its companion road bridge have been scanned as part of a project to help inspire the next generation of Scottish engineers. Using a mobile mapping system engineering technology company Renishaw captured data by road and boat. The Forth Bridge is an iconic engineering landmark located nine miles west of Edinburgh, in eastern Scotland. Opened in 1890, this cantilevered railway bridge has been nominated as Scotland’s sixth UNESCO World Heritage Site. Until 1917, when Canada’s Quebec Bridge was completed, the Forth Bridge had the longest single cantilever bridge span in the world. Together with the Forth... (read more)

Geodesy and Land Administration - FIG Working Week 2017

GW was not at the Working Work in Helsinki in May, but FIG publishes most of the technical papers presented at the conference on its website www.fig.net. Richard Groom has been sifting through the proceedings and has drawn together papers on Geodesy and Land Administration and a few other interesting topics. The code in parenthesis indicates the session number where the papers were presented. It is some time since GW published an article by Chris Rizos on the Global Geodetic Observing System (GGOS). Kutterer (TS03C) provided an update. His paper gave a general overview of GGOS and its work in... (read more)

Something for Everyone - GEO Business 2016

GeoBusiness returned to the Islington Business Design Centre for its third year with a larger exhibition, more visitors and, if anything, an even buzzier atmosphere. GW’s team at the event report. The industry’s biggest players seemed to have bigger stands and there were more new exhibitors. Perhaps more importantly, the event is attracting interest from surveyors’ clients as well as surveyors. No longer are we talking to ourselves! The first session of the first day started with inspiration in spades. Tom Cheesewright, an ‘Applied Futurist’ gave the audience his vision of the geospatial future. The future, according to Cheesewright, is... (read more)

Why a Smart City is the Only Possible City

There are not so many people around thinking about the area they dwell in. I mean really thinking about efficiency, economy, aesthetics, and standards. We rarely even raise our heads up and turn our eyes away from our smartphones to contemplate the scenery or enjoy the view in a city – and more often than not it’s justified. City of the Past In the past, cities were organized next to water supplies with the distance not exceeding one mile from a river or lake, which made water delivery possible. With the invention of the automobile, cities stretched to indecent distances,... (read more)

Students Scan the Past to Preserve the Future

Dr Pascal Sirguey had waited two years for this day and took a few final minutes to savour the moment. It was a sunny morning in early 2017, and students, historians and scholars had gathered in Arras, France, to attend the remembrance ceremony of the Battle of Arras in World War I. While 1918 marked the official end of World War I, the commemoration paid tribute to the little-known yet significant contribution of New Zealand to the war efforts in helping win the legendary battle. Sirguey’s efforts would document one more chapter in the Great War as its centenary approached.... (read more)

UK is a Leader in Heritage Mapping

The mapping of historical cultural features, which we will call heritage mapping, is mainly based on photogrammetric methods. Mapping for this purpose has been going on for many years using a great variety of techniques. There are also many applications from conservation and archaeology to museums and public understanding. Early Developments The use of photogrammetry for recording buildings was introduced during the late 19th century by the German civil engineer and architect Albrecht Meydenbauer, and techniques and applications have been developing and extending ever since. In the United Kingdom, the Royal Commission on the Historical Monuments of England (RCHME) was a government... (read more)

Christ the Redeemer Reconstructed in 3D

UAV Deployed in Challenging Conditions to Reconstruct Iconic Statue
The famous statue of Christ the Redeemer in Rio de Janeiro has been reconstructed in 3D using a UAV. Challenging weather conditions and the sheer size of the monument meant that careful planning was required to complete the project and maintain safety. Thousands of pictures were captured around the statue and processed to create a large and accurate point cloud and a textured mesh. (By Lisa Chen and Sonja Betschart, Pix4D, and April Blaylock, Aeryon Labs) Fascinating images of the statue of Christ the Redeemer in Rio de Janeiro, Brazil, were seen around the world during last year’s FIFA World...
