Moving Ordnance Survey Forward - Interview with Nigel Clifford

Since the beginning of June 2015, Ordnance Survey GB has had a new CEO. GW met him in London recently. Nigel Clifford comes to the job via a career covering the NHS, e-commerce, British Telecom and other mobile players. I met Clifford in OS’s Geovation Hub in the City, a buzzy building which also houses Catapult, a body promoting future and smart cities. Tucked away at the end of a large open plan office full of enthusiastic young innovators, we had a wide-ranging discussion for over an hour that included his views on whether geospatial is special, OS’s strengths and...

OS Net - Preparations for Future GNSS

Ordnance Survey (OS) has just updated its geodetic infrastructure. Mark Greaves, Lead Consultant at Geodesy, describes these developments and takes a look at shorter and longer-term geodetic issues for surveyors. OS Net is Ordnance Survey's national network of over 110 permanent, geodetic quality, GNSS stations. GNSS observation data is streamed in real-time to a central hub and access to the national standard realisation of ETRS89 is enabled through the following services: Real-time GNSS correction services available to customers of OS Net commercial partners. Real-time GNSS correction services for OS surveyors. High rate (i.e. 1Hz) RINEX data for use in commercial... (read more)

Downtown Dublin as a Lidar Point Cloud

A Highly Accurate, Diverse and Dense Annotated Laser Scanning Dataset of a City Centre
The advance of Lidar data acquisition technologies is substantially increasing the amount of spatial data obtained and it is becoming cost-prohibitive to process it manually. Artificial intelligence (AI) has now started to offer cost-effective solutions to analyse and utilize those big datasets. AI can be employed for scene understanding, accurately detecting objects and classifying 3D assets. These are the significant fundamentals of several applications including autonomous navigation, intelligent robotics, urban planning, emergency management and even forest monitoring. The most popular types of 3D spatial information for such applications are Lidar and imagery data. This article describes the dense annotated ground-truth... (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)

Imaging the Banqueting House Ceiling

John Hallett-Jones, Director of Glanville Geomatics, describes a new technique for high-resolution imaging of historical objects like ceiling paintings and mouldings where sub-millimetre pixel resolution is called for. Over recent years, heritage recording has undergone massive change. Improvements in terrestrial scanning, digital imaging and the ability to navigate these datasets using mobile devices has provided the surveyor with a wealth of new opportunities to deliver quantitative and qualitative information at a resolution never before commercially achievable. In order to provide a cost-effective approach to digital recording to the historic sector, we highlight a technique developed to swiftly capture high-resolution seamless... (read more)

The UK at the FIG Congress

Summer is here, the long balmy evenings are being enjoyed, BBQ’s are fizzling out and the World Cup is back at last. Spring is traditionally a very busy period for RICS and this spring was no exception. Hopefully this column will give you some insight into where, with who and how RICS Geomatics has been engaged with the UK and the wider world. FIG Istanbul 2018 The main ‘event’ for the global surveying profession was without any doubt the quadrennial FIG congress which was held in the Istanbul, Turkey during early May. FIG has been organising international conferences since its... (read more)

Meet us there - GEO Business 2014

The Business Design Centre at Islington in North London is a large space with an arched roof giving it the feel of a Victorian railway terminus. It was the venue for this year’s geo event – GeoBusiness 2014, which was, for the first time, actively supported by the RICS, CICES and TSA via the Survey Liaison Group and by the AGI. The conference lived up to its promise as well as being an opportunity to chalk up some hours of CPD. There had been an enthusiastic response to the call for papers, resulting in a set of quality presentations which... (read more)

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)

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)

Photogrammetry Aids River Restoration

Structure-from-Motion photogrammetry and GIS are being used to chart the success of a river restoration project in Northern England. Many of the world’s rivers are degraded as a result of modification of their flow regimes. This modification (‘regulation’) results from the construction of impoundments such as dams and weirs, as well as the water abstractions and tributary diversions that often go hand in hand with impoundment. Flow regulation affects the transfer of sediment downstream and, as a result, natural habitat-forming processes are compromised. These processes are important for aquatic organisms, so changes resulting from flow regulation affect the ability of... (read more)
