Last month the use of GPS tracking in football came under scrutiny, following a seven-minute delay in a League Two game. In the interests of player safety, Plymouth manager, Derek Adams, complained about the devices worn by the Wycombe team as they lined up in the tunnel. The device, worn between the shoulder blades underneath the shirt, is surrounded by padding, although it is debatable whether this padding is designed to protect the GPS tracker or the player! An article in The Guardian (2015) quoted the Plymouth Manger: “it’s a hard object and a dangerous bit of equipment”. However, after consulting the rules and regulations, the matter was resolved; FIFA ruling permits players to wear GPS trackers – official termed Electronic Performance and Tracking System (EPTS) – during matches and, this season, the Football League has also sanctioned their use. There are currently 19 English Football League clubs registered to use these devices.

So why are GPS trackers being used in football? Has sports science turned into Big Brother?

Tracking devices have been used by football clubs, behind the scenes, for some time, but have only recently been used in competitive matches. In this sense, football is lagging behind rugby, which has long used such devices to monitor player performance and health. Speaking to the BBC, Wycombe midfielder, Matt Bloomfield (2015), explained the importance of GPS tracking devices in football. Electronic Performance and Tracking System (EPTS) devices track each individual player’s every move on the pitch and can provide a wealth of data about the player; how far they have run, how many sprints they have completed, their position on the pitch over time, their heart rate over time, and how much work their body has done. The feedback players get after each game, Bloomfield (2015) states, is then used in training sessions to recreate the number of sprints or distance covered in games. This is certainly one way to decrease the number of players deemed ‘not match-fit’. Furthermore, Bloomfield (2015) stresses the importance of EPTS devices in monitoring players’ well-being, as their stats can highlight when they are fatigued and, therefore, more susceptible to injury. Thus, prevention of niggling injuries is another major benefit.

The use of GPS in football redefines the space of the football pitch. Understanding the ways in which footballers use the space is every sports geographer’s dream. The data collected by the devices can be used to map players’ use of space and track the flows of their movement throughout space. This is not dissimilar to the use of Geographical Information Science (GIS) to map and monitor transportation systems. In this further example of mapping mobile subjects – although admittedly on a much larger scale than the football pitch – data about transport is used to map and analyse the spatial networks within which interactions occur, showing the routes and flows of movement (Miller and Shaw, 2015). Miller (2007) recommends a ‘people-based’ approach to GIS, rather than the traditional ‘place-based’ approach. The increasing mobility and connectivity of people means that the relationships between people and places are becoming more complex. Mapping the “individual in space and time”, Miller (2007:503) argues, provides a more complete analysis of our interactions with space. The theory behind this approach has its roots in 1960s ‘time geography’, which considers the dynamic use of space in human activity, the constraints and fluidity of these activities, and the temporal aspects of them. From this we have evolved location-aware technologies, which collect space-time activity data in real time, such as global positioning systems (GPS) and radiofrequency identification (RFID). The use of location based services (LBS) has become ubiquitous in everyday life; social networking, parcel tracking, and Google Maps all use locational data to provide us with real-time information about what is around us. Locational privacy is a thing of the past, as our movements across space and time are constantly being logged. It is, therefore, not surprising that technology is now being used to track the individual movement of athletes in sport.

The use of GPS trackers in football can certainly give teams a competitive edge and reassure fans that their favourite players will be in top condition. They are useful ways to track movements on the pitch and the ways in which the space is used, as well as monitoring players’ health and fitness. There is, however, another implication that I’d like to propose to you; these GPS trackers are re-defining footballers’ bodies. Tailoring training and recovery to individual players’ needs, whilst not new, has taken a massive step with the use of tracking technology. No longer the achievement of individual skill and managers’ tactics, football teams are being moulded around quantitative observations of individual players’ movements and bodily responses. The goalposts have been moved, and expectations of players’ performances and capabilities are being raised accordingly. Footballers’ bodies and performances are becoming hybrid collaborations between player and machine. Thus, it seems, even in the beautiful game, we cannot escape the pervasiveness of computers in modern society and the ever-diminishing distinction between humans and technology.

Geography, Urban Geomorphology and Sustainability

Leave a reply

By Mary Thornbush, Brock University, Canada

WordItOut-word-cloud-1071134With the expansion of cities around the world, there is an increasing emphasis within geography to consider urban environments, and the impacts humans have on the environment more generally. This opens up opportunities for the development of human-environment investigations within the context of current urban studies.

Working within the context of human impacts on their environment, it is possible to integrate studies so that they holistically examine both human and physical components of the environment. This has already been an integral part of human geography, but is novel within physical geography and geomorphology specifically, where the sub-field of urban geomorphology has recently experienced some growth from the framework of human-environment interactions. In addition, sustainability has gained attention within geomorphology, and there has been, for instance, a recent special issue on ‘Human Impacts on Landscapes: Sustainability and the Role of Geomorphology’ published in Zeitschrift für Geomorphologie by Hudson et al. (2015). This approach recognizes the importance of long-term studies within the domain of geomorphology, and is applicable to studies of environmental change that is currently affecting cities and shaping urban geomorphology.

The key landscapes examined within an urban context are still diverse, encompassing (for instance) rivers, karst, uplands, deserts, tropics, etc. Within this special section on ‘Geography, Urban Geomorphology and Sustainability,’ there is a focus on rivers, karst and applied geomorphology, with six papers delineating urban geomorphology in settings where there is a concentration of urbanisation and natural environments have been altered by humanity and natural processes, which in turn modify human structures, as is the case with the weathering of historical buildings and structures. Case studies are central to this special section, illustrating key contemporary issues from a long-term perspective and considering the future of human-environment interactions and landscape change.

Specifically, this special section of Area presents a diversity of papers that range from Europe to North America. First, Thornbush (2015) provides a long-term assessment (16 years) following the implementation of the Oxford Transport Strategy (OTS) in central Oxford, UK. She employs the historical buildings located in the city centre as a measurement tool in order to gauge post-OTS environmental change. Second, Randall and Baetz (2015) relay their land-use diversity index (LDI) as a GIS-based model to determine sub-urban sprawl applied in Ontario, Canada. Third, Martín-Díaz et al. (2015) offer a post-war examination of planning policy and land-use planning in Sarajevo that is relevant to urban development within geomorphology. The second half of the special section focuses on rivers. A fourth paper by Sammonds and Vietz (2015) approaches urbanisation in greenfield sites from the perspective of stream naturalisation. Fifth, Shuker et al. (2015) likewise approach stream restoration, but from a hydromorphological perspective. Finally, Booth and Fischenich (2015) similarly address stream restoration through their channel evolution model that focuses on urban sustainability.

Together, these papers contribute towards the development of urban geomorphology from a sustainability perspective of long-term landscape change. Theirs is an integrated approach of human-environment interactions in urban settings. With more human impacts on the natural environment, it is necessary to acknowledge and consider more human-affected landscapes as well unaffected natural landscapes, which are increasingly harder to find. Separating the human-nature signatures in the environment is becoming a challenge; however, such interdisciplinary investigations could make a contribution towards the development of urban geomorphology and sustainable environments.

About the author: Dr Mary Thornbush is an Adjunct Professor within the Department of Geography at Brock University, Canada. Her research interests include: interdisciplinary and applied geomorphology; weather science and landscape change; and geomorphological fieldwork and field-based training.

Humanitarian mappers’ response to the Nepal earthquake

3 Replies

By Joseph J. Bailey (@josephjbailey), University of Nottingham, UK.

“In the days since the earthquake in Nepal, thousands of humanitarian mappers have sprung into action to fill in gaps in the map in the affected area” (Mapbox article, dated 27th April 2015, two days after the Nepal earthquake).

The earthquake that occurred in Nepal on the 25th April 2015 is the largest quake to affect the region since 1934 and one of the most devastating natural disasters in recent memory, killing thousands of people. Aftershocks present an ongoing threat, including one on the 12th May killing over 100 people. Accessing the affected communities requires explicit and accurate knowledge of the area’s infrastructure.

The world’s population continues to grow, making natural disasters increasingly devastating. However, technology develops in parallel. Emerging technology can and is helping with disaster management. More people than ever across the world now carry in their pockets a very powerful tool; a smartphone connected to the internet and equipped with an inbuilt GPS unit. This can be used to quickly and accurately record spatial information not only on a day-to-day basis but also after a natural disaster where possible. Additionally, and often more realistically amidst the destruction where the event has occurred, people nowhere near the disaster itself can contribute towards mapping efforts using satellite information, providing an invaluable resource for those on the ground.

A recent paper in Geography Compass (Haworth and Bruce, 2015) reviewed volunteered geographic information (VGI) for disaster management (prevention, preparation, response, and recovery). VGI technologies allow for near-instant sharing of relevant geographic information for disaster management and the resource implications for generating these data are minimal. This article also assesses the associated challenges of these data, including: “lack of data quality assurance and issues surrounding data management, liability, security, and the digital divide” (p. 237), the latter referring to the lack of technology in some areas so that people can benefit from and contribute to VGI projects (this is improving every day, however). The authors stress the importance of VGI in disaster prevention as well as response, but response is the main subject of this post herein.

There are many examples of VGI, and one of the big projects where such data are used is OpenStreetMap, which I focus on here. Founded in 2004, driven by limits on access to spatial data and the dominance of proprietary software, and in response to the increase in affordable GPS and satellite navigation units, “OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world” (Wikipedia). It uses data contributions from volunteers all over the world (Wiki – OSM Map Production). Such an open, editable geographic information system (GIS) based on crowdsourced data is an incredible resource. It has huge potential from making lives easier day-to-day, to saving lives in extreme circumstances like during and after a natural disaster.

In the context of the 2015 Nepal earthquake, OSM has been invaluable, providing accurate and up-to-date maps that are used by aid organisations and local disaster response teams. Indeed, according to an article on Mapbox (by Eric Fischer, 27th of April), just two days after the quake struck, “more than 2000 mappers … recorded 13,199 new miles of roads and 110,681 new buildings” (see the image below from the Mapbox article). Naturally, these figures will have increased substantially since this article as mapping efforts continue. The OSM volunteers rapidly digitised satellite images after the earthquake, providing much-needed maps and data to humanitarian organisations (OSM Nepal Earthquake Wiki). The process is coordinated by the Humanitarian OpenStreetMap Team (HOT), who communicate with relevant organisations to focus mapping efforts. Anyone can use the resultant maps and associated routing services for free.

The use of VGI will only grow alongside technological development and, importantly, so too will accessibility to this technology through projects such as OpenStreetMap. There are known issues of data quality and so on, as discussed by Haworth and Bruce (2015), but ultimately this technology can only be a good thing. Hopefully it will mean that populations at risk of large-scale natural disasters, like those in Nepal most recently, will be able to be helped more quickly and effectively, thus mitigating the impact.

Gridlock: GIS in transport planning

Leave a reply

By Joseph J. Bailey (@josephjbailey), University of Nottingham, UK.

“It is not hyperbole to state that we are witnessing a revolution in the human sciences … fuelled by a stunning advancement in capabilities to capture, store and process data, as well as communicate information and knowledge derived from these data” (Miller and Shaw, 2015; p. 180)

We have all been there, haven’t we? Powerlessly sitting in a vehicle amidst of a sea of pollutants. I am of course referring to the traffic jam. They are often the result of rapid urban expansion around city centres that were simply not designed with such volumes of traffic in mind. It is something that people the world over can relate to. Indeed, Statista (with TomTom data) recently released a graphic that identifies the world’s worst cities for gridlock (also see: IB Times, Forbes). Drivers on a thirty minute commute (with no traffic) in Istanbul, Mexico City, Moscow, Saint Petersburg, Bucharest, and Recife (Brazil) could expect to spend more than 100 hours a year in gridlock; that’s over 4 days a year just sitting in a car stationary in traffic! The sheer volume of waste that traffic causes (fuel, money, time) has hugely negative effects on the environment, economy, and human wellbeing. Environmentally, of course, pollutants are also a significant problem, posing risks to both the natural world and human health.

‘GIS’, or ‘Geographic Information Systems’, is now ubiquitous in geographical research and beyond. It refers to an array of processing and analysis techniques that use spatial data and theory (see the QGIS introduction to GIS online). GIS can be used across an enormous range of research from natural disaster management and monitoring deforestation, to biodiversity science and geomorphology. This post considers GIS in transport planning.

Miller and Shaw (2015), writing in Geography Compass, recently discussed GIS-T (GIS for Transportation), providing an update update on their previous work from 2001. The quote at the top of this post says a great deal in itself and, while people referring to data volumes and computing power is so common it is bordering on a cliché, it really is true and we need intelligent systems to make both sense and use of it. The heart of GIS-T projects is identified as a georeferenced transportation database, probably using a spatial network in which locations, nodes (e.g. junctions), distances, and directions can all be represented in a model. With this spatial network in place, mobile objects (e.g. people, vehicles, freight) can then be incorporated and modelled. Terrain (e.g. if somewhere is very steep) and human-imposed features (e.g. congestion zones, toll roads) can also be considered where they may affect traffic flow and peoples’ decisions.

We are now comfortably into the 21st century, and new technologies can help provide information for GIS-T models. Most notably, GPS technology is widely available in most vehicles and on most individual people (via a phone or tablet). Such mobile tech means that “it is now feasible to collect large amounts of data from a wide range of mobile sensors in real-time or near-real-time at high spatial and temporal granularity” (Miller and Shaw, 2015; p. 185). A better understanding of how people move should help with urban planning, in terms of both policy making and infrastructure design, by allowing scenarios of certain decisions (e.g. creation of a congestion zone where people have to pay to drive into the city centre) to be incorporated into the GIS-T models.

GIS is a fantastic geographical analysis and problem-solving tool that needs to be fully harnessed and applied to a range of problems (from traffic management to conservation planning) if we are to cope in our increasingly busy and complicated world. As we have seen here, GIS-T has enormous potential in urban planning, utilising quantities of fine-scale data that we have never had at our disposal before. Hopefully this will be able to make for more efficient and sustainable cities, towards improved environments, economies, and human wellbeing.

Redefining the Upper Amazon River

A full descent of the world’s largest river can be likened to a full ascent of the highest mountain, with various natural challenges along the way. The Amazon River is generally considered the mightiest river in the world because of its incredible volume (it carries over eight times as much water as the next largest river, the Congo), its maximal length (which may be slightly more than that of the Nile), and the importance of its basin for the world’s ecology. The entire Amazon River, including its source, has intrigued the public, geographers, and adventurers for centuries.

The allure of descending the Amazon goes back at least to the time of Francisco de Orellana, whose 1540 expedition started on the Napo River. Since then, dozens of expeditions have sought to travel the entire length of the Amazon. For adventurers, the location of the river’s source is critical because it defines the route, including the most difficult part of the journey through the formidable whitewater of the Andes mountains.

During most of the past century, the source of the Amazon River was considered to be the Apurimac River, based on the belief that it was the most distant upstream extension in the Amazon basin. Initial attempts to navigate the river starting in the 1950s ended in disasters with team members drowning in the difficult rapids. Although many other would-be Apurimac-Amazon adventurers failed in their attempts, several teams have successfully made the descent – starting with Piotr Chmielinski and companions in 1985-1986.

However, our new research results published in Area demonstrate that the most distant source of the Amazon is not the Apurimac River as previously thought.  Rather, it is the Mantaro River, a neighbouring stream that joins the Apurimac to form the Ene River. These new findings change the uppermost ~800 km of the Amazon source-to-sea journey, including all of the whitewater. This result drastically changes the journey down the Amazon.

While gathering data for the article in Area, I realized that distance measurements based on topographic maps and satellite images were limited because these methods often have low resolution and sometimes do not show current river channels. Simply measuring distances on topographic maps and satellite images would not suffice, because these often have low resolution (and therefore errors) and sometimes do not show current river channels. The best way to obtain an accurate up-to-date measurement is via direct GPS tracking on a descent of the river. It is for this reason that I descended both the Mantaro and Apurimac Rivers from their sources – no easy task with the numerous class V rapids (the most severe whitewater classification) on each river.

Since my initial scientific expedition in 2012, which also included a GPS-measurement of the entire Amazon to the Atlantic, at least two other expeditions have descended the Mantaro River down the Amazon to the sea, prompting attention from the paddling community and public. Had such attention been directed to the Mantaro River decades ago, it might have prevented its desecration with pollution and damming.

About the Author: James Contos is director of the non-profit river conservation organization SierraRios and completed the Area study along with   Nicolas Tripcevich, an archeologist at UC Berkeley who has expertise with GIS software and the ancient cultures of Peru.

Mapping Class

Leave a reply

By Benjamin Sacks

Five Boys

Conceptions of class remain inseparable from contemporary society, according to a BBC-commissioned study. The Great British Class Survey, undertaken by the BBC’s Lab UK and faculty at LSE, University of Manchester, University of York, City University London, Universitetet i Bergen, and Université Paris Descartes, surveyed 161,000 people across the British Isles. The study’s authors argued that ‘class’, as twentieth century writers tended to define it, was ‘too simplistic’.  Rather than an equation of ‘occupation, wealth and education’, class was actually formulated around ‘economic, social and cultural’ dimensions, of which the traditional structure only formed a part. Along with the traditional classes – elite/upper class, middle class (itself a category distinct from US conceptions), and working class – new divisions had arisen: technical middle class, new affluent workers, traditional working class, emergent service workers, or ‘precariat’, the authors’ term for ‘precarious proletariat’. Predictably, the study’s publication catalysed a diverse range of media responses. The Financial Times reminded its readers of how deeply entrenched class was in British history. Tristram Hunt recalled William Harrison’s 1577 Description of England: there were ‘four degrees of people’, led by ‘those whome their race or blood or at least their virtues doo make noble and knowne’. A letter to The Guardian compared it to the hierarchy used by the National Statistics Socio-economic Classification scheme (NS-SEC). The Guardian itself wondered whether the new hierarchy was more reflective of the television programme ‘The Wire‘ rather than of British society.

Critics aside, the BBC survey indicated the continuing influence of class, whether desired or not, in shaping how different people think, act, speak, travel, and shop. Geographers have long been aware of the role and perception class played in British and international cultures. Indeed, in 1995, Gary Bridge (Rodney Lodge) called for a standardised, ‘consistent application of class analysis’ when examining urban and rural gentrification. In a 2004 Transactions of the Institute of British Geographers study, Anthony J Fielding (University of Sussex) documented the spatial organization of Japanese cities by class. Critiquing previous, recent accounts that suggested that Japan’s rapid, postwar capitalist transformation had erased, or at least minimised cities’ ‘social geography’ (defined by Fielding as the distinction of classes or groups in space), Fielding used GIS programming to visually and textually demonstrate how major cities have, in fact, been organised by class and social standing, as is the case in most European and North American cities. Interestingly (and importantly) however, through the collection of mapping of this aggregate data, he suggested that the degree of spatial ‘segregation’ was generally lower than in the West. Comparing Kyoto and Edinburgh, Fielding proposed that the former’s spatial organisation was different, and it experienced a lower, but still quite identifiable level of segregation (p. 83). Indeed, Fielding’s study of Japan implicitly mirrored Jon May’s study, also from the University of Sussex, seven years previously. In the 1996 study, May, evidently fatigued from ‘theoretical literature’ on London’s complex social dynamic, created visual and textual maps of Stoke Newington (p. 195).

Class, it almost goes without saying, infected the storied halls of Lowther Lodge. For some two decades at the turn of the twentieth century, the Royal Geographical Society had debated whether to elect women to the fellowship (women had applied for admission as early as 1847, but the issue was not seriously considered until the 1890s). If women were to be admitted, as Morag Bell (Loughborough University) and Cheryl McEwan (Durham University) recalled, then, as the debaters proceeded to argue, they must be of the right social and economic standing. Returning to more recent issues, JoAnn McGregor posited the rapid growth of Britain’s Zimbabwean community within class ‘differences and identities’, in a fascinating shift from more mainstream studies of Robert Mugabe-era emigration. Regardless of whether the BBC survey has lasting impact, geographers will continue to observe, critique, and play with class.

Geographic Information Systems –a Tool for Geographers or a Science in Its Own Right?

Eyjafjallajökull eruption in 2010 by Terje Sørgjerd

Eyjafjallajökull eruption in 2010 by Terje Sørgjerd

There’s an interesting paper by Mordechai Haklay in Transactions of the Institute of British Geographers which starts off by describing an ‘Iron Sheep’ exercise at the recent Association of American Geographers conference – one could be forgiven for thinking it’s a trial for inclusion in the next Bond film.

The paper itself provides an interesting history of geographical information science. The paper doesn’t touch on the difference between geographical information “science” and “systems” so for other geographers perhaps slightly unsure like myself, the science part is the theory behind the use and application of the technology/software that comprises geographic information systems.  Perhaps this confusion is itself a product of the ‘cleavage in GIS between two traditions, that of spatial information on the one hand and that of spatial analysis on the other’ (Goodchild, 1992).  Mordechai’s paper explores whether geographical information science is a sub discipline, or not, of Geography.

Back in the 1854 John Snow, one of the forefathers of modern day GIS as well as epidemiology, mapped out the Soho cholera outbreak using points to represent individual cases and revealed a cluster around a public water pump on Broad Street.  This led to identification of the contaminated water pump as the source of the disease.  For teachers, this legendary Cholera map in various GIS formats and suggested lesson content is freely available via the James Madison University National Centre for Rural Science and Mathematics Education.

In a more modern day context, Peter Webley, Assistant Research Professor at the Geographical Institute, University of Alaska Fairbanks, who back in my undergraduate days was a Postdoctoral Research Associate in our Geography Department, uses GIS as a means to bring together fieldwork and remote sensing data for operational use. He’s now part of the IAF-AVO remote sensing group and is responsible for the volcanic ash cloud model forecasts for volcanoes around the world.   You might well ask, why focus on this individual?  It is creative individuals like him, that put to use GIS software to translate geographic data, models and forecasts into something tangible, understandable and operational for the rest of society.   For instance he developed a system to analyse thermal hotspot volcanic monitoring in Central America to help provide the information necessary for disaster warnings (UAF, 2012).  In addition to the day job, he’s part of a team that have developed “MapTEACH” which is a fantastic educational tool to help teachers and their students in Alaska get to grips with GIS whilst simultaneously preserving their community heritage, their history told through stories, with mapping.

Hopefully this post will have inspired some of you to seek out more information on GIS and for the teachers amongst you, perhaps to spend some lesson time on it.  The Royal Geographical Society has a GIScience Research Group, so do check out its pages if you’d like to find out more.  There’s a “Virtual Issue” of Transactions of the Institute of British Geographers with papers over the past five decades covering the use of computers in geographical and cartographical research, a substantial amount of which, including Mordechai Haklay’s paper, are free to download so do also check them out.

For those of you in London, interested in debating this/want to meet people who use GIS in their jobs/research, the London Trainee and Student GIS Community are meeting for drinks at the aptly named John Snow pub, Sunday 20th January at 2pm, 39 Broadwich Sreet, London W1F9QL, the more the merrier!
