We had a great GISRUK conference this year. We were online again (as we were in 2020), because of Covid-19, with Scott Orford at Cardiff University hosting, we had a really smooth running online conference. There was a very strong field of submissions, with 24 short papers and 43 long papers being presented, with a significant proportion being presented by Early Career Researchers. The papers themselves and the recordings are all available on the GISRUK website. Attendance was also very good, with typically >100 people attending the keynotes and >50 people in each of the presentation sessions.
I coordinated the Early Career Workshop sessions before the main conference, and while I am biased, I think they went really well, and the ECRs who attended said they were really useful sessions. The main sessions were on Zoom, and we also experimented a bit with the Wonder.me platform for a quiz and networking, which worked really well.
As ever with GISRUK we had an incredibly wide range of topic presented, from new spatial methods to big data, spatial inequalities and participatory GIS. Uber’s H3 hexagonal grid appeared several times, being a really useful new geography for many types of analysis. One of the big positives is the fact that indexing is a lot easier when working with this geography. It was also great to see presentations from the commercial sector, including Tomas Holderness from AddressCloud, presenting on their work with serverless infrastructure.
GISRUK awards prizes, and this year I managed to actually see most of the winners – parallel sessions makes this a challenge, and there have been years I haven’t seen any of the winners! This years winners were.
Best Long Paper: 23 Naturally Urban? Tackling Inequalities in Urban Greenspace and Wellbeing, by Victoria Houlden
Best Short Paper: 53 Georeferencing historical telephone directories to understand innovation diffusion and social change, by Nikki Tanu, Maurizio Gibin and Paul Longley
Best ECR Paper: 65 Do we need legends? An eye tracking study, by Jess Hepburn, David Fairbairn, Philip James and Alistair Ford
Best ECR Paper: 48 Geo-information tools for stakeholder engagement in environmental decision-making: “best practice” recommendations from a UK case study, by Caitlin Hafferty, Robert Berry and Scott Orford
CASA Prize: in the memory of Sinesio Alves Junior Prize, 38 Profiling the Dynamic Pattern of Bike-sharing Stations: a case study of Citi Bike in New York City, by Yunzhe Liu, Meixu Chen, Daniel Arribas-Bel and Alex Singleton
The papers from GISRUK are also now available on Zonodo, a long term repository where all GISRUK papers will now be kept. The presentations were also videoed, and the recordings are now available. Next year University of Liverpool are hosting GISRUK, and hopefully we will be back to an in person conference then! Looking forward to seeing you there!
Online conferences are everywhere now – and everything now has online as a prefix. The GISRUK 2020 conference was no exception, and originally scheduled for 21th – 24th April, it was postponed and moved online, to 21st to 23rd July. GISRUK is the largest annual GIS research conference, bringing together academics, researchers and students, as well as those from government, commercial and other sectors interested in GIS and its applications.
We had a excellent selection of keynotes, including Tao Cheng, Mark Birkin, Bruno Sánchez-Andrade Nuño and Krzysztof Janowicz. One theme that cropped up several times was that of networks and graphs as a new spatial data format, that one day might sit alongside vector and raster data sets – I will need to update my Intro to GIS slides! Tao talked about how we can think about networks underpinning urban areas, that we can turn any spatial data structure into a network, and that often the network links are much more important that the nodes themselves. Also, graphs and networks lend themselves to temporal data, with network links changing over time, which traditional GIS data structures have struggled to capture. Krzysztof Janowicz extended this to talk about knowledge graphs, linked data and the semantic web, and how graphs as a data structure underpin this. This allowed him and his team to develop knowledge based geo-enrichment, allowing us to ask questions of data that required both geo and non-geo inputs. He also included a great quote:
No conference is complete without the social element, and I have yet to attend a conference that truly cracks this problem. No amount of video conferencing software can replicate waiting in line for lunch and having a chat with whoever happens to be there! GISRUK has a social roulette space where people could go and chat, but it didn’t get a lot of use, potentially because of timing and a 10:00 – 17:00 programme being quite full on. Two elements that worked really well and created a good range of social interaction was the social quiz and tea time conversation with Sarah Wise. James Haworth confirmed the British tradition of being great at creating quizzes by putting together a four round quiz for us; identifying universities based on their logos, identifying cities that GISRUK had been to before based on interesting facts (e.g where was Marks and Spencer founded?), some great GCSE Geography questions(!) and identifying cities based on aerial photos.
Social wise, this was continued the following evening by an absolutely amazing panel discussion hosted by Sarah Wise. The panel, Denise McKenzie (Benchmark Initiative, Geovation, UK), Licia Capra (Professor of Pervasive Computing, Department of Computer Science, University College London) & Monica Stephens (Ph.D., University of Arizona, 2012), fielded Sarah’s questions with ease and provided amazing insight into their current work, challenges facing the GIS community. She also included some fun questions, including your favourite game (I’m glad to see Settlers of Catan was mentioned several times!), and what tattoo would you get to represent your work, in a reflective, pessimistic Pacific Rim style (I can’t remember the exact phrasing – please do comment if you remember!). Monica advised everyone to start blogging and putting your thoughts out there – something I can heartily recommend. Denise also gave some great careers advice for the ECRs (and all of us) listening – be open to what opportunities come your way, and that no-one would have been able to describe her current role to her when she was 21! This particularly resonates with me; my career plan was to do the traditional academic path and become a lecturer, professor etc. and I have taken a wildly different route, but suffice to say that I am happy with what I am doing, and happier that I think I would be if I was a lecturer (although that is another blog post!).
One massive plus of the online model is that it increases accessibility, and we had a great many more people register for GISRUK online than in person (~600 registrations, compared with 200 in person). We had people from all across the world, which is a great change to our usual UK and northern Europe focus.
As usual, GISRUK gives prizes to the Best Paper and Best Short Paper, voted on by the attendees. I would like to offer my congratulations to the prize winners this year:
I had a wonderful three days in Edinburgh attending the most recent FOSS4G UK 2019 conference, based at Dynamic Earth in Edinburgh. Edinburgh has never had better weather, and I was assured by the locals that this was not normal! FOSS4G conferences have a special vibe to them that makes them unique to any other sort of conference. Various people have already written about thatvibe, much more eloquently that I can.
There was a great selection of workshops and talks, and I ended up attending primarily workshops, which is a first for me. I have a particular interest in collecting data in the field, and so went to the workshops in QField and Input; both mobile phone apps to provide an interface to collect data on your phone, and then synchronise this back with a QGIS project when you get back to the office.
The wonderful Kirsten Reilly from ThinkWhere hosted the workshop on QField, explaining how we could setup a project in QGIS, synchronise this with the app to go out into the field. We had some of the usual technical issues, but nothing unusual for a practical session.
I also attended the Input workshop, run by the skilled Saber Razmjooei of Lutra Consulting. Lutra have developed Input as a alternative to QField, re-creating the app from scratch, and ensuring that Input can be operated on iPhones as well (QField is currently Android only). There are a lot of similarities between the programs, with QField being a bit more developed (i.e. less buggy) but Input having a cleaner interface and slightly more features. We actually also got to go outside and test the app out, which was great. My phone (a Fairphone 2) was actually not very happy with either app and my experience wasn’t flawless (but your mileage may vary, as they say).
The key differences are:
QField only works on Andriod, Input works on Andriod and iOS.
QField uses a cable to transfer files from your computer to the phone and back, Input uses the cloud (a website called Mergin, developed by Lutra) to manage the synchronisation process.
One key feature that Input has (which QField lacks) is the ability to record tracks (or lines) logging the route you took, where as QField can only record points.
QField is relatively mature whereas Input is very new.
Overall I would say that Input just edged ahead of QField. If you are looking to use these in the field, try out both!
One great talk was from Mike Spencer, discussing the pros and cons of using R or QGIS for cartography. There are so many options out there, and his talk gave some great examples of amazing outputs from R and QGIS. There was a whole slew of talks that I would have liked to have attended, but couldn’t because things clashed. Fortunately all of the talks at FOSS4G UK 2019 were live streamed and recorded, which allows anyone to experience the conference.
I led a workshop on contributing to QGIS documentation, which was very well received with 10 participants. Contributing to documentation is a key element of open source software and is something that often gets neglected. We covered how QGIS documentation is structured, how to work with GitHub to make changes on the web, and how to work with documentation locally. The workshop was only 90 minutes long, so we didn’t have time to actually make any changes to the QGIS Documentation, but we did have great fun experimenting with the example repository I made for it. Thanks to denelius, Nikosvav, mikerspencer, SteveLowman, myquest87, hopkina, cearban and TBreure for attending and getting involved.
At the Community Sprint on Sat 21st, a group of 9 of us had a go at a variety of coding and documentation issues. I led a group of three experimenting with a number of QGIS Documentation issues. We all had a deep dive into GitHub and learnt a lot! We fixed a range of issues from unclear documentation to new features in the QGIS Master that needed to be added into the documentation. These included:
The organising committee put together a great conference and captured the unique feeling of a FOSS4G conference. Many thanks to all of them, and they even created a Lego video to celebrate the amazing conference. FOSS4G conferences happen all across the world, so keep your eyes open for one near you in the future!
GISRUK is the annual GIS Research
conference in the UK which showcases the latest in GIS (Geographical
Information Science) and Geomatics Research from the UK and across Europe. I
attended the 4-day conference at Newcastle University and it
was amazing to see the latest developments from across the geospatial
One of the key themes for me that emerged from the conference
was the debate between whether spatial data is ‘special’ or is it data just
another data type, one among many? For many years when GIS was a niche area
requiring specialist skills to use, there was a clear argument that spatial was
special. Now the bar of entry to using spatial data is much lower, through the
use of tools such as Google Earth, Tableau and even ArcGIS Pro, which means
many more people can get the benefit of using spatial data and analysis.
Spatial data is another tool in the toolbox of analysts, which allow us to be
solution architects (solving problems) rather than geo-engineers (tinkering
with projections and file formats). I don’t think we are yet at the point where
using spatial data is as easy as using an Excel table, but we are so much
closer than we were even just 5 or 10 years ago. The traditional desktop GIS
package (ArcGIS / QGIS) is no longer the only way of working with spatial data:
advanced users have more data science orientated solutions such as Python or R,
and non-technical users can get great maps from Tableau. In fact James
Bowles found many organisations in the third sector (charities and
NGOs) use Tableau to do data analysis (including spatial analysis) rather than
using tools like ArcGIS.
Spatial data is becoming more widely accessible, with many
users in the third sector choosing Tableau for their spatial analysis, over
traditional desktop GIS such as ArcGIS or QGIS.
One of the regular features of the GISRUK Conference Series
is a key focus on Early Career Researchers, those students who are currently
studying MScs or PhDs. About 60% of them will go straight to work in industry
after their studies, so this is a great opportunity for them to find out more
about working in industry. Both junior staff and senior consultants came in from
explain what ARUP do and why the students’ skills are vital in industry. One of
the big areas of growth is the combination of remote sensing and machine
learning; these skills are very sort after by industry and there are some very
exciting developments in the earth observation field. Machine learning and AI (artificial
intelligence) are gaining a lot of coverage, both in terms of how and where we
use them, but also from the point of view of ‘how do we use AI ethically?’, and
‘what new questions do we have to think about when we are using AI & ML?’.
One of the keynote speakers, Prof. Renee Sieber
talked about the importance of public participation in what she termed ‘GeoAI’
(AI applied in a geospatial setting) and the fact that the fact that AI is not
unbiased at all; it reflects our societal biases and we need to be careful when
The use of spatial data is fundamental to all of the work
presented at GISRUK, and availability of data is often not as clear cut as it
really should be. In the panel discussion on ‘How will
the opening up of geospatial data help the GIS community?‘ one of
the key elements that was discussed was data infrastructure. The provision of
metadata is often quite important in terms of being able to select suitable
data for specific projects, and if we are to further develop automated data
process (including data selection) then comprehensive metadata is key to much
of this, and currently fairly lacking. Dr Gobe Hobona,
from the Open Geospatial Consortium, demonstrated how the OGC have been
instrumental in developing a range of standards that are key to the interchange
of spatial data between different software and organisations, including the
provision of metadata. Gobe also mentioned the developments of UAVs, both as
tools for spatial data collection but also as transformative decides in
geospatial interoperability, allowing access to more and more varied data
sources. They are also very cool, such as the spectacular swarms of UAVs we saw
at the recent Beijing
UAVs were mentioned across many different themes in the
conference, including for data capture, combination with AI (to identify cracks
in road surfaces) to impact on birdlife in wildlife reserves. They are clearly now
entering a phase where they are part of a wider toolbox, rather than a novelty
in themselves, and so are maturing into a new data source and product. There
was also a very interesting presentation by Kevin Minors on
crowd management, including techniques for modelling the crowd as a whole from
a series of static data points, which has a wide application in highly variable
crowds, such as railway stations.
Overall this was a great conference with a fascinating insight into the cutting edge of research in spatial data and GIS. Next year GISRUK is at UCL and Birkbeck, University of London, April 21st to 24th – see you there!
I spent a great couple of days up in Liverpool, attending the North West Digital Research Methods Festival at the University of Liverpool. It was great to be back in Liverpool and catch-up with colleagues and friends from my post-doc days there in 2013-16. The city has changed quite a bit, and my old office now overlooks a major building site instead of a green park!
The conference looked at Digital Methods from a broad social science point of view. It was great to spend some time thinking about digital methods from a different perspective. Key to all digital methods are longevity and there were lots of discussions about how data resources are made available to scholars in the long term; including decisions made to simplify a website interface to ensure it will remain working for longer with limited support.
It also made me think about how we process data. Warren Pearce presented on social media data and was critiquing the fact that we often focus on the text content of messages, and ignore the visual elements. This is missing out on a key element of the conversation (think of any social media content you have recently looked at) and the visual elements should be included in the analysis. My initial thought was that this was a technological hangover, with text being much easier to process than visual. However, I learnt that there is also a cultural element with text based information being seen as much more valuable than pictorial information. Warren also highlighted a fascinating visualization of the front pages of the New York Times, highlighting how it had changed from just text to a mixture of text and black & white images, then to text & colour images. Warren’s recent paper on the topic is at https://www.tandfonline.com/doi/full/10.1080/1369118X.2018.1486871
There were a whole range of presentations looking the digital research and digital data, from a wide range of different perspectives. These included using physical objects to encourage interaction and engagement in a museum environment, to considering the best ways of increasing accessibility of digital archives such as photo libraries of African Rock Art or historical criminal life courses. Have a look at https://twitter.com/hashtag/nwdrm for Tweets from the conference.
The second day consisted of a series of practical workshops, which included one run by me on GIS. I was pitching GIS as a great digital method and I think I may have converted some people!
I would really recommend that everyone considers attending conferences outside of your usual ‘academic sphere’ – you never know what you are going to see, what ideas might be sparked off, or what future contacts & employers you could be meeting!
During the amazingly sunny weather a few weeks ago, I managed to spend a couple of days indoors, hiding from the sun at the ESRC Research Methods Festival at the University of Bath. Every 2 years, the National Centre for Research Methods have organised this conference to showcase unique and new methods from across the social sciences. The conference covered everything from ‘Multi-scale measures of segregation data’ and ‘Quantitative methods pedagogy’ to ‘Do participatory visual methods give ‘voice’?’ and ‘Comics as a research method’.
It was also fantastic to meet a range of academics and researchers who I would not normally meet. I met a number of people who I had communicated regularly with on Twitter, but never met in person before!
I was presenting in a session on ‘Multiscale measures of segregation data‘, where we were discussing different approaches to how deprivation can be measured across different locations. One of the major characteristics of grouped spatial data is the MAUP (Modifiable Areal Unit Problem), where the method used to group your data will have an impact on the results of any analysis. The session was a great collection of presentations, all of us looking at similar issues but often taking quite different methods to approach them.
I showed how using variograms based on the PopChange data set to look at spatial segregation can help avoid some of the impacts of imposing scales on the data, and instead use the data to tell us at what scales the variations are taking place.
Across the whole conference there was a range of content using scripting languages, and R and Python featured significantly across the board, to the surprise of some of the participants, including me:
Till next time, Bath! What a fantastic time I had at #RMF18! The academia has pleasantly surprised me with plenty of work done using Python, R and C++. pic.twitter.com/838zvCtSGt
Like most conferences, there were so many interesting sessions and it was often difficult to choose which track to attend! The keynotes were all thought provoking. Danny Dorling presented a range of interesting information on current levels of inequality in the UK, and warned us that it is likely to get worse before it gets better. Donna Mertens called on all of us to think about how our research can change things, and if it doesn’t, why not?
It was a great methods conference, and reminded me about how many different methods are out there. If you would like a chat about how using GIS could help with your research or work, please do give me a call on 01209 808910 or email at firstname.lastname@example.org.
Earlier this week I have a very nice couple of sunny days in London attending a training course and a conference. It’s a nice change to attend a course (rather than delivering one!) and is also a great opportunity to add to my CPD log (particularly important for my Chartered Geographer status with RGS-IBG).
Some of my transport around London!
On the Monday I attended a half-day workshop on Linked Data, organised by Dr Claire Ellul at UCL and run by Bart De Lathouwer from the Open Geospatial Consortium. I’d come across the term linked data in various different situations, but hadn’t really done much with it, and this was a great opportunity to learn about it. The key bit about linked data is that it is solely formed from triples, sets of three, in the form “subject, predicate, object” such as “The pool – is – blue” or “student – name – value”. It also is a fundamentally different way of structuring data from a “traditional” relational database and so avoids many of the limitations, but also requires a completely different way of thinking about the data. This is quite a jump from what we are used to, and I think it will take a little while for linked data to properly take off. This is a good resource (http://www.opengeospatial.org/blog/1673) for some information on how OGC are working with Linked Data.
Queen Elizabeth II Centre, home for ESRI Annual Conference
On Tuesday it was ESRI UK’s Annual Conference, based at the Queen Elizabeth II Centre near Parliament. It was a great conference, with a massive range of examples of how ESRI’s various different products could be used. There were some great examples of using Strava data to help Jersey understand cycle route usage across the island; using this data to identify and remove bottlenecks in their infrastructure. We also had a presentation on how City Engine was used by Disney to help them develop the city behind the film Zootropolis (2016), allowing them flexibility to create and tweak a whole city design with limited time and resources.
A good turn out for the conference!
Unsurprisingly a significant chunk of content was on conversion from ArcMap to ArcGIS Pro, their new flagship product. There is a big focus around users having an identity and using this to both access local and remote resources for ArcGIS Pro (including, no doubt, an element of licensing). There was also a reasonably strong theme about pushing out GIS to non-GIS users, and making it easy to use for new-comers, particularly with the development of ArcGIS Pro which, for example, automatically includes a base map when you start a new project. Possibly not ground-breaking for regular users of GIS, but a big help to someone coming to GIS cold – now they have a map they can add their data to, rather than just a big blank space (when you start ArcMap).
If you would like a chat about getting more from your GIS (ESRI or other packages!), or GIS Training for small groups, please do email email@example.com or give me a call on 01209 808910.
Last week I attended an amazingly sunny GISRUK (Geographic Information Science Research UK) conference in Leicester. I have fond memories of Leicester, as I completed my BSc Geography (2003-2006) and MSc GIS (2007 – 2008) there. Much of the university and city has changed, but an amazing amount is still the same – both in the Bennett building lecture theatres and certain well frequented take-aways!
University of Leicester – Attenborough Tower (L) and Charles Wilson Building (R)
I coordinated the Early Career workshops, where those early in their GIS careers (including, but not limited to, PhD and MSc students) came together for two half-day sessions to find out more about GIS as a career in academia and industry, to learn more and compare notes about their respective PhD/MSc experiences, and most importantly, to get to know each other before the main conference! We had a great variety of input from James Norris (Ordnance Survey / Group on Earth Observations / AGI), James Kendall (RGS), Dave Unwin (ex University of Leicester & Birkbeck), May Yuan (Editor-in-Cheif IJGIS, University of Texas at Dallas), Addy Popy (ESRI UK) and Katie Hall (ESRI UK).
Early Careers session in full flow
The main conference had a great selection of talks and presentations covering every application of GIS from archaeology, to crime, health, transport, and urban studies! It is always a challenge to work out which of the three parallel sessions to attend, and I can’t attend everything. Particularly of note for me was Alex Singleton’s keynote on ‘Why Open Data are Not Enough’, discussing some of the issues with open spatial data, particularly in terms of data longevity which very much reminds me of this XKCD comic, and still really hasn’t been solved for spatial data. This was rather well illustrated by the CDRC Data Store that has been developed through the Consumer Data Research Centre; there is no mechanism for ensuring this continues after the CDRC funding finishes, and this is the norm with many academic projects.
Alex Singleton: Why Open data are Not Enough
There was also a great presentation by Sam Cockings looking at how we can better model day time populations, from a variety of data sources. Integrating many real time data sources is going to be a key aspect of spatial data management in the future and I can see many projects using the skills and technologies Sam described.
Next year GISRUK 2019 will be in Newcastle University, and I look forward to seeing you there!
After 6 months or so of collaboration FOSS4G UK 2018 finally happened! I was a small part of the dedicated team who brought the conference together and it was an amazing experience. Thanks to James (@JamesLMilner), Tom (@tomchadwin), Isabel (@IsaUlitzsch), Sam (@SamRFranklin), Max (@GeospatialMax) and Dennis (@goldrydigital) as well as Jo Cook and Steve Feldman who gave us occasional nudges in the right direction with their experience from FOSS4GUK 2016 Southampton. Organising the conference felt a bit like organising a wedding(!) in that once we had picked the date, location, catering and sorted out the guest list, the rest more-or-less fell into place! Not that I intend to do either again in the near future!
Unfortunately I wasn’t around for the team photo on Friday, but I was there in spirit!
The conference itself went amazingly well and it was great to see so many people there who were so enthusiastic about open source geospatial software. Unfortunately I was only able to attend Thursday, but I managed to take part in some great workshops on pgRouting and Satellite Data, learn some new things, make some new contacts and baby sit the room-to-room live feed!
It was a struggle to work out which stream to attend and I’ve seen from Twitter (#FOSS4GUK) that Tom Armitage went to town with the ‘May the FOSS be with you’ Star Wars theme, the highlight being a presentation using a light sabre rather than a laser pointer:
We will post links to all the slides and material we can on the website – if yours are not there yet, send them over or submit a PR. I do hope we can do this again, and if people would like to volunteer for the next conference, please make yourself known!
If you’d like a chat about potential for OS Geo training for individuals or groups, please do send me an email firstname.lastname@example.org or give me a call on 07717745715.
On a sunny Friday at the end of half term, Nick attended the TEDx Truro event, ‘Beyond Barriers’ running at Truro and Penwith College. TEDx events are the ‘little brothers’ of the main TED events, the world famous series of short videos given in the area of Technology, Education and Design under the banner ‘Ideas worth spreading’.
TEDx events are independently organised and the Truro event is in its second year, with a sell-out crowd of 250 attendees. This years talks covered a really wide range of topics, covering everything from dyslexia, gender dysphoria, mental health, sex work, to biochemistry, depression, robots and artificial intelligence.
There was an amazing buzz in the auditorium, this continued during the breaks; there was idea sharing, discussions and even a selfie with some local celebrities! It was a great networking opportunity, meeting people from Software Cornwall, Pirate FM, Plymouth University and a whole host of local SMEs.
The talks around the area of mental health particularly resonated, with both Will Coleman (from Golden Tree Productions, famous for being the driving force behind The Man Engine) and Emma Wright (working for a national cancer charity in Cornwall) talking about how they had often presented one face to the world at large, but at times had another that truly reflected their feelings and experiences, which very few people saw. Many other speakers also discussed mental health in passing, and it is vital for mental health to be discussed more openly and easily than it is at the moment.
TEDx was organised by a great group of volunteers, so many thanks to them for organising everything and making it run smoothly. They are already planning for next year – head over to http://tedxtruro.com to find out what it’s all about, and we hope to see you there next year!
