Why Location Matters in Data Analytics - AGI GeoCom 2016

AGI GeoCom 2016 boasted a new format, new speakers and a new venue. Stephen Booth reports. We live in an age on constant change and churn so this year’s AGI conference was no exception. A major departure from past formats of two or more days of presentations and keynotes, today’s uber-busy world needed something sharper, quicker, more attention-grabbing. A one-day event at the home of geography, the Royal Geographical Society, attracted nearly two hundred to hear 12 invited speakers talk about location and data analytics. The audience seemed different; yes, the usual faces and greybeards were there but new faces... (read more)

The Role of Geological Data in the Smart City Agenda

Advances in the use of GIS and 3D modelling software have meant that there is now a greater opportunity to develop geo-environmental information systems for urban development, argues Dr Katherine Royse of BGS. By 2050, 70% of the world’s population will be living in cities. Cities have a major impact on the social and economic development of nations. They consume 75% of the world’s resources. This evolution raises a very important change with regard to the deployment and management of all types of infrastructures within cities. The sustainable development of our cities is of paramount importance if cities are to cope...

Online GIS and a Perfect Storm for Local Government

The author thinks we have been using the wrong metaphors. We shouldn’t allude to aircraft taking off but to storms and perfect ones at that, argues Chris Mewse. Getmapping has been in the forefront of providing aerial imagery and other services for many years, as well as promoting the benefits of collaborative on-line mapping. The potential for the use of digital mapping and GIS in local government has taken a long time to take off amongst the lower tiers like parish and town councils. There have been several delaying factors including the cost of software, cost and licence restrictions on... (read more)

Lighting up the Enterprise - Esri User Conference 2016

May saw Esri UK’s biggest yet user conference. Held in the QEII conference centre in Westminster, the event attracted over 3,000 preregistrations drawn by the opportunity to attend a choice of 60 individual sessions spread over seven tracks from keynote presentations, special interest groups and workshops. Launching the event under the banner “Lighting up the Enterprise”, Esri UK MD Stuart Bonthrone spoke on change driven by the technology of GIS. Robust websites, rich libraries of content are all helping to personalise information for users. We are seeing the consumerisation of IT. The challenge, said Bonthrone, is to spatially enable the...

Buzzes and Fizzes - Esri User Conference 2014

A brilliant sunny day in London was a chance to recharge enthusiasm for GIS and learn about some startling new applications of the technology. On the wall of one of the reception rooms of the QEII conference centre is an immense wooden sculpture. Entitled ‘On the Island’, it is the work of Sir Edualdo Paolozzi, born in Scotland of Italian parents. Created in 1986, the work is a mass of geometrical shapes that, for our community, serve as an easy metaphor for what today’s 3D city GIS can achieve. Alas, the full benefit of this remarkable work to delegates at... (read more)

Shedding Light on the Land Sector

How Open Data for Cadastral Records is Gaining Traction
Despite the enormous importance of good land governance for sustainable economic growth and social justice, land administration remains a sector that is lacking openness and transparency in many parts of the world. Land registry and cadastral records are often deemed too sensitive to share, unless acquired for a fee, or the records themselves may be unreliable or in formats that are not easily accessible. In geographies where the rule of law may not be strong, this presents opportunities for government abuse and corruption. A 2013 study by Transparency International found that one in five people around the world reportedly had... (read more)

Dense Image Matching for Easy 3D Modelling

New Threat and Opportunity for Professional Surveyors
Normally when something is too good to be true, it is not true. But in the case of dense image matching (DIM), professional surveyors should look twice – because their clients, and certainly those in the construction, infrastructure and 3D city mapping markets, certainly will. 'GIM International' asked John Taylor, who is responsible at Bentley Systems for reality modelling in Asia Pacific and in the global defence market, for his insights into DIM. Dense image matching (DIM) did not arrive like a bolt from the blue. It has been around in the photogrammetric world for the past two decades but, through further... (read more)

3D GIS in China

Chongqing Survey Institute Realised What Many Still Dream Of
Since 1998, the Chongqing Survey Institute (CSI) has been managing the 3D geoinformation database, including terrain, buildings, underground pipelines, geology and underground buildings, of the Chinese megapolis of 30 million people. For the commercial market, CSI’s 3D Mobile group focuses on combining the indoor and outdoor environment with e-commerce systems. Meanwhile, its BIM and GIS Integration group concentrates on three fields: geological survey, construction sector and municipal administration. Chongqing is a city of unique topographical and landscape features. It is built on mountains and partially surrounded by the Yangtze and Jialing rivers, making mapping the city a big challenge for...

Career Expectations for the GIS Professional: Consulting

This is the second in a series of three articles pertaining to what you can expect as a GIS Professional on a chosen career path. This part refers specifically to the world of consulting, one which can be defined in three ways. Firstly, if you seek job security, then do not consider a career in this field; secondly, if you wish to forever tackle high-angle professional challenges, then consulting is meant for you; thirdly, if you wish to do what GIS’ers like to refer to as “real GIS”, then be wary as there are many flavours of consulting. The Bane... (read more)

Urban Energy Modelling - Semantic 3D City Data as Virtual and Augmented Reality

The visualisation of results from urban energy modelling and simulation is a crucial part of energy research as it is the main communication tool among scientists, engineers and decision-makers. Energy modelling and simulation results are directly linked to spatial objects, and 3D therefore becomes a necessity. The multiple interactive 3D visualisation environments that exist are mainly targeted as 3D viewers for use on desktop machines and lack immersive components that enable users to truly immerse themselves, explore and interact with the real environment onsite. In this study, the team focused on a holistic approach that implements a seamless transition from... (read more)
