The Next Chapter for Ordnance Survey - Interview with Nigel Clifford

Since June last year Ordnance Survey GB has had a new CEO. GIS Professional met him in London recently at the Geovation Hub, of which more anon. Nigel Clifford comes to the job via a career covering the NHS, e-commerce, British Telecom and other mobile players. He has a degree in geography from Cambridge and is a Fellow of the Royal Geographical Society. 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 of which more anon. Tucked away at the end of a large open plan office... (read more)

Mapping the Past

Anyone who has tried to accurately match old Ordnance Survey maps with the current Landranger series will soon realize that it is not an easy task. Brian Quinn explains the painstaking process that Cassini Publishing has been through in creating its unique range of historical maps. Amelia Earhart’s observation that “it’s easier to start something than to finish it” is certainly true, as any writer stuck at the bottom of page one will testify. But when, and how, do things finish? Often there is no definite conclusion but rather a steady progression that leads past or round the original goal... (read more)

Lively Agenda in a Busy Day - AGI Scotland 2016

A trip north for GIS Professional's editor found him immersed in a different culture where even the units of measurement can be different. AGI Scotland’s annual conference was a reminder that they do some things differently there. This was an interesting and busy day in Edinburgh of mainly short lively presentations, debates and networking that attracted some 160 people. After a scene-setting introduction by AGI Scotland Chair Prof Bruce Gittings, we were off on the first of two keynotes. North of the border, local government is guided and informed by the Improvement Service, an organisation to help councils improve the... (read more)

Geospatial in the Video Game World - Interview with James Coote

Just how much crossover is there between the worlds of geospatial and video games? GIS Professional turned to Andy and James Coote, father and son working in different parts of the computer industry. Andy has been involved in geospatial for many years and will be familiar to many readers, whilst James is the director of an independent video game studio, Crystalline Green Ltd. Andy asked James to give us his take on where the worlds of geospatial and video games intersect. Andy Coote: The geospatial industry can now provide 3D data at a very detailed level for any part of... (read more)

GIS-based Cartographic Representation of Avalanche Forecasts

Annually, snow avalanches in Scotland are the cause of a significant loss of life. As a naturally occurring disaster they are unique in nature, usually being highly localised events, and often in remote areas. Their victims are often voluntarily at risk for recreation purposes and become the trigger of their own avalanche. Typically, avalanche prone areas are often those that recreationists most desire to use. Controlling access to these areas is ethically dubious and efforts to increase the safety of recreationists must therefore focus on educating and informing risk-based decision processes. Avalanche Forecasting Avalanche forecasting seeks to safeguard recreationists in... (read more)

2D and 3D Enrichment of Panoramas

Visualisation of Topographical Features Improves Functionality
The use of panoramic images has become widespread in many governmental agencies and companies, especially in the last couple of years. It is possible to integrate 2D spatial features (e.g. building outlines, parcels, utilities etc.) with panoramic images to enable the proper visualisation of topographical features in a 3D environment. Verbree et al. (2004) have shown the advantages of augmenting underground conduit pipes and cables into panoramic images, thus allowing better visualisation of otherwise invisible features. The geometric augmentation of 2D features into panoramic images enables users to identify, query or analyse any geographically related information in a 3D environment.... (read more)

Interacting with Big Geospatial Data

Methods for Virtual Exploration and Visual Analysis
Advances in capturing techniques such as laser scanning and photogrammetry have significantly increased the volume of geospatial datasets. Big geodata has become an important asset for analysis and decision-making, but also poses a challenge for state-of-the-art visualisation techniques. This article presents research results addressing this problem for the infrastructure and planetary science application domains. The methods discussed here enable users to fluently explore and efficiently analyse the growing wealth of geospatial data.  The data volume of 3D reconstructions is steadily growing for two reasons. Firstly, there is a demand to increase the accuracy of data acquisition, now reaching even sub-millimetre... (read more)

Emergency Mapping Gets HOT

Paul Stewart explains how the Humanitarian OpenStreetMap Team applies the principles of open source and open data for economic development, disaster preparedness and emergency relief around the world. Non-for-profit humanitarian organization HOT is a global online community of volunteer digital humanitarians, who apply the principles of open source and open data to create and provide free, detailed and up-to-date maps for NGOs and local communities fostering economic development, enhancing disaster preparedness and engaged in emergency relief. The organization’s objectives are to provide remote data creation during humanitarian crises, to connect open mapping communities with humanitarian actors, to support deployments to... (read more)

The Bright Era of Earth Observation Satellites

In helping overcome a wide range of global challenges, the geospatial industry is relying on satellite information to an unprecedented degree. In this article, Italian geospatial solutions developer Gianni Cristian Iannelli, provides a background to the satellite industry and discusses some of the exciting Downstream opportunities which are emerging through it. Over the past 50 years, advances in satellite technology have contributed to the emergence of the Earth Observation (EO) revolution. The following is an attempt to identify the key milestone events, which have taken the geospatial industry to this data-rich point in time. The first of these event occurred... (read more)

Opensource GIS - A Disruptive Force or Driver of Innovation?

In order to better understand the increasing availability and emerging popularity of opensource GIS options, you first of all need to place it in a wider evolutionary context. From the 5th Century’s Babylonian stone carving map, through to the creation of the Mercator navigational Projection, and later on to the development of the printing press, the power of mapping has always been about its ability to communicate and disseminate knowledge and ideas about our world. GIS is the most recent phase of mapping evolution which carries on this tradition. Prior to its commercialisation in the 1980s and 1990s, GIS was... (read more)
