Following on from an early email exchange about how Google defined “Newcastle” it got me thinking about other providers and how they define the city. Twitter for instance provides a bounding box the centre of which is the middle of Nun’s Moor (as does Google but the point location is not the centroid of it). As you can see from the image there is wide variation. Note that a couple (Yahoo/Michelin) place the point location at the point roughly where the centre of the text “Newcastle upon Tyne” appears on certain map products.
The mean centre of the point locations excluding the centroids is shown as well.
So I visited a pile of map sites and extracted their default location (and/or bounding box) and plotted them on the map. For twitter I sent a tweet from “Newcastle upon Tyne” and captured the coordinates using the API. Just to be rigorous I installed TOR browser which obfuscates the IP address to ensure that location was not being picked up from the browser and tried different browsers as well. The OS point for Newcastle upon Tyne was collected from the Gazetteer service provided through Digimap.
The vaguely serious point here is that we now routinely use APIs to get data from and its location yet those locations provide spurious precision!
Following our blog post looking at the distances of football grounds from their nearest railway station, we had a think about other interesting football-related analysis that we could do. Having previously been a holder of an away season ticket, I thought that one interesting comparison might be to investigate which football fans would spend the longest on public transport to visit away games.
In order to do this analysis we used the Google Maps Distance Matrix API (https://developers.google.com/maps/documentation/distance-matrix/ ) to calculate the time and distance you would have to travel on public transport between each football club, to arrive at 2pm on a Saturday. The locations of the football grounds were used as the start and end points for each journey since we obviously don’t know where supporters actually live!
Below is a list of the 5 longest away trips between any pair of Football League or Premier League clubs. You could look at this as the nightmare FA Cup draw if you’re committed to going to the game, and the ones you really don’t want to be switched to a Friday night for TV coverage.

NEW BLOG POST CORRECTING ERRORS HERE
As I imagine happens at many work places the coffee break for the Geospatial group often brings up some lively debates. Whilst today’s debate itself wasn’t exactly lively it did pose an interesting question. Which football ground is the further away from a mainline railway station? The answer put out there Hillsborough. Not content with this guesswork I ran a simple piece of analysis. Luckily we have the football grounds from the work we carries out with the football tweets (previous blog & site) and the the railway stations from work carried out for ITRC (http://www.itrc.org.uk/).
Football League Stadia
GB Railway Stations
Therefore all i had to do was look at the nearest railway station to each ground and calculate the distance between them. I did this by loading both datasets into PostgreSQL + PostGIS and performing a few simple queries. The results are below: Whilst Hillsborough wasn’t the furthest it wasn’t far off.
Ideally we’d look at the distance along the UK road network and not straight line distance. But this seems somewhat overkill for answering this question.

Last week a book, ‘The Future of National Infrastructure: A Systems-of-Systems Approach’, by reasearchers from the ITRC (Infrastructure Transitions Research Consortium), was released and made available for purchase. The book provides insights into a range of the work undertaken in the ITRC project, from the economic and demographic projections to 2100 for the UK, to the analysis performed with developed national scale models for critical infrastructure systems and the developed underlying database and visualisation tools used. Synopsis:
“The future of national infrastructure: A system-of-systems approach provides practitioners, decision-makers, and academics with the concepts, models and tools needed to identify and test robust, sustainable, and resilient strategies for the provision of national-scale infrastructure. It takes a “system-of-systems” view on the interconnected infrastructure networks – including transport, telecommunications, energy, water, and waste-management – and derives an integrated vision on infrastructure provision required to ensure that nations have an infrastructure system that is fit for the future.”
Our own Stuart Barr, David Alderson and Craig Robson have all been involved in the research behind the book which has been carried out over the past five years, with a single chapter devoted to the work where their time has been focused, though they have also contributed to much of the other work. The chapter, ‘Database, simulation modelling and visualisation for national infrastructure assessment’, documents the tools developed here at Newcastle; the underlying database for the infrastructure models including developed schema’s as well as the visualisation and reporting tools for both the data used for the modelling and for the results from the simulation work and subsequent analysis. This research has involved the development of a national infrastructure database containing a suite of data for many of the critical infrastructures in the UK along with the associated data such as economic and demographic modelling outputs for demand modelling as well as hazard data for modelling the resilience of the infrastructure networks/systems. Along with this, a schema and associated functions for the simulation and modelling of national infrastructures has been developed as well as a PostgreSQL/postgis schema for networks and the wrappers for integration into the python package NetworkX. On top of these, a suite of web based visualisation tools have been developed with facilities to view and interrogate the results from the infrastructure modelling and simulation, tools to view the underlying demographic data, one of the main drivers for the modelling. More details of these outputs are available in the book, and further publications in the form of journal articles are in preparation.
As part of Mustafa Hameed’s PhD research, he spent some time doing fieldwork in communities in his native Iraq. The research is assessing the role of VGI (volunteered geographic information) input in re-building the Iraqi cadastral system after years of chaos. The work done in the town of Al-Hilla (south of Baghdad) during December 2015 and January 2016 concentrated on several aspects: firstly, interviews with land administration professionals yielded an assessment of the current land administration system and opinions regarding the role of VGI; secondly, sample attribute data pertaining to land parcels was collected from professionals, gatekeepers of selected communities, and some owners of parcels in those communities; finally, geometrical data was collected by the owner of parcels who identified their parcel boundaries using three different techniques (GPS app on a smartphone, iPad tablet, and paper-printed satellite image). It was pleasing to see such a large number of local people willing to volunteer their knowledge, time and services to this project.

As a research group a small number of us have been involved in the ITRC project over the past five years, namely Stuart Barr and Dave Alderson. Craig Robson joined the ITRC ranks in January, pausing his PhD work to help complete the final phase of the research required by autumn 2015. ITRC (Infrastructure Transitions Research Consortium) has been investigating the future of the UK’s national scale infrastructure with regards to how it must develop to meet ever changing demands and how climate change amoungst other factors will affect the resilience of those networks we rely on.
Our role in the project has centered around the development of the tools which would allow the five year project to be completed and included, but was not limited to, the development of the central database for all data for the project, and the support tools which would enable the analysis to be undertaken and results reported. It is on this later point where most of the past 6 months have been spent; developing a reporting tool for the presentation of the results from the long-term infrastructure planning aspect of the project.
The developed reporting tool allows users to view results from the each infrastructure sector (e.g. transport or waster supply), or view cross sector results, a set of similar metrics computed for each sector allowing for direct comparisons between them on there performance. For each sector a range of model outputs can be viewed from the level of emissions produced, to the running costs per year to the cumulative capital investment required. Results are shown not only at the regional level, but where possible at the sub-national level through the government office regions for example where the models output data at this granularity. This allows the tool to show data not just in charts, but also through maps, allowing new insights to be learned which may not be identified through non-spatial results. More detail on the tool, along with images and the like will be provided in a specific post at a later date, but for now a small selection of images below exemplify the tool.
With the end of the project looming near an event was organised at the ICE in London on the 15th October where the key results and impacts from the project could be disseminated to a wider audience with those key members behind the research all being present to answer questions and discuss their work. At the event we were available to demo the reporting tool and discuss the complexities behind the database for those interested, while a set of slides were used to give a overview of our work. More generally two videos (below) were produced giving an overview of the project and the one on the resilience of the UK’s national infrastructure.
Anyone with any experience of working/visiting the Geomatics group will know that, just like in most other academic establishments, visits to the pub at the end of a hard week are just as important as anything else that happens during the working week. To this end, the Friday night pub call is now well and truly part of the culture of the group, and without some would be inclined to say they would feel lost without this. However, the visit to the pub could be argued to have fallen into the shadow of the call email itself, which depending on the sender, can tell a complex story which few understand and can only read with a face of utter bewilderment.
So, to cut to the chase, as an exploratory piece of ‘academic research’ we have compiled a comprehensive database, going back to the creation of the GWRS call email list, 2008, until the current day. Every pub call ever made over the past 7 years, that’s 397 Fridays, the pub and the person who made the call have been recorded (though some are blank due to public holidays and missing data). Further data has then been added including the weather to allow us to explore the call data in more detail, and attempt to understand any patterns which may or may not be present.
To start with, and to end this initial post here, below are some key initial statistics on the data we have collected.

An amazing summer school took place last week in Obergurgl, Austria (http://www.uibk.ac.at/geographie/summerschool/). The focus was to investigate the various close range photogrammetry remote sensing techniques for alpine terrain research. Such an international environment made the atmosphere very interesting. I met other researchers from Austria, Germany, Italy, Poland and even Equador!!! Professors in remote sensing and photogrammetry from Germany and Italy insipred us with their talks.
The days were very busy with data collection in the alps and data processing, however the fieldwork gave us the opportunity to explore the beautiful mountains and refresh our minds. The best part of course was the social events with tasty austrian beers. The weather was incredibly warm, even the locals became crazy in such a warm environment; I couldn’t believe that Austrian drivers use the horn, this is a Greek habit!
The local newspaper reported the event on their website: http://www.tt.com/panorama/katastrophe/10251350-91/katastrophen-besser-lesen-lernen.csp
The organiser Dr. Martin Rutzinger successfully managed to create a great event and make everybody happy.

The central location of Vienna has allowed me to engage with some more people in the past few weeks. I and the other two members of the International Cartographic Association Statutes Committee, Ferjan Ormeling (Netherlands) and Bengt Rystedt (Sweden) met here a couple of weeks ago to discuss proposals for the ICA General Assembly in August. We were joined by my host here, ICA President Georg Gartner, and the Secretary-General Laszlo Zentai from nearby Budapest. Ferjan, Bengt and myself also form half of the Working Group on International Map Year (http://mapyear.org) and were able to make some further plans for this UN endorsed event. My ICA work in helping organise our Commission workshop in Curitiba in August continues from afar.
I spent a couple of days in Budapest this week – giving a seminar on VGI at the Eotvos Lorand University Department of Cartography & Geoinformation (a lively group of half a dozen staff and plenty students). It was good to meet again with Laszlo’s colleagues with wide ranging interests (Matyas Gede is currently exploring cave surveying and 3D visualisation, along with citizen mapping of tourist activity; Zsolt Torok is a historian of cartography, but also researches eye tracking; Andrea Podor, from a nearby university, examines environmental GIS and educational issues).
Back in Vienna I have been meeting with colleagues in my extensive host department, Geodesy and Geoinformation which has 7 research groups (https://geo.tuwien.ac.at/research-groups/). Gerhard Navratil in Geoinformation has interesting views on the topic of VGI and cadastral systems, which I am continuing to engage with Kaizer and Mustafa back in Newcastle. And Gottfried Mandelburger, familiar to Newcastle geomaticians having spent some time with us, has discussed further the archaeological work I have been interested in doing with LiDAR.
I’ve been doing some ‘map use studies’ by finding orienteering events to participate in whilst here – and it’s great that some wonderful terrain is available so close to Vienna and accessible by public transport. I even had a run in the suburbs of Budapest in torrential rain one hour after my seminar finished: a bit beyond the call of duty, but good training for a main event – the academic orienteering championships at the Danube Park next week (yes, there are enough university staff and students in Vienna to have a formal closed championship).
Last week’s trip to the USA reminded me how cartography and GIS are central to American academic geography. I was invited to the Geography and Geology department of the University of Nebraska at Omaha (UNO) to give a research presentation on my work using LiDAR-sourced data to examine archaeological landscapes. It was good to join later in some of Mike Peterson’s classes: it was clear that his new book, ‘Mapping in the Cloud’, acts as an excellent basis for the syllabus of a course on web mapping. I also discussed the August pre-conference joint ICA Commissions (Education & Training/Maps & the Internet) workshop in Curitiba, Brazil: I chair the former, and Rex Cammack from UNO the latter, so we were able to firm up some of the co-organisation in person.
A couple of days later and 500 miles to the east, the AAG conference in Chicago beckoned and my Education & Training hat was retained, presenting a paper about accreditation in cartography, participating in a panel discussion about the role of cartography in GIS education, and invited to sit in with the luminaries on the UCGIS board crafting the extended ‘Body of Knowledge’ in GIS&T. There was also time to visit the Newberry Library in Chicago, where Volume 6 of the History of Cartography (published by the University of Chicago Press, and covering the 20th century) was launched. At 1,960 pages with 1200 illustrations, in two enormous volumes, it was astonishing to see the magnum opus in print. Luckily, contributors have been offered a .PDF copy, so I did not have to check in excess baggage at the airport …
Back in Vienna this week, I visited Gilbert Kotzbek at the Universitat Wien (which celebrates its 650th birthday this year). I have been discussing his PhD work on the use of GIS to examine football data with him for some time now, and he has created some excellent Python-scripted ArcGIS tools to input, filter, and analyse the staggering amount of spatial and attribute data captured during a game and interpreted after (1/25th second interval positional data for every player and ball, plus information about every event – tackle, throw-in, offside, corner etc). What’s missing in the data is the third dimension – it would be interesting to contrast the style of a long-ball team which keeps the ball in the air a lot, with a close-passing, tiki-taka side. I also had the chance to remind myself of teaching in a classroom, when I had a class with the 15 students of the International Masters MSc course in Cartography (who are all studying in Vienna this semester, having been at Dresden and Munich for previous semesters). This is a very international bunch from Egypt, China, Canada etc and closer to home from close-by Slovakia. The topic was VGI, so I was able to convey some of the thoughts which came out of Maythm Al-Bakri’s PhD study from a couple of years ago, and outline what Kaizer and Mustafa are doing in Newcastle now.
bis zum nächsten Mal …
