GeoBusiness 2014 – a preview

GeoBusiness_smallGeoBusiness 2014 is less than a week away.  This is a new event and I am looking forward to seeing what it will be like.  The organisers have certainly pushed the event, with short magazine inserts listing who is exhibiting and presenting.  GoGeo will be there and i thought i would explain why we are attending and what we hope to get out of the event.

It’s new and it’s big

Pretty self-explanatory, but also significant.  This is a chance to speak to all the major software vendors and find out what enhancements they have in the development.  In addition, there are a host of companies that offer GI service.  I want to see what these are up to and report on what looks innovative and interesting.  These companies collectively employ a significant number of GIS graduates each year.  Many of them are exploiting new and emerging technology such as unmanned aerial vehicles (UAV).  As such, they are really quite dynamic places to be employed as a fresh-faced graduate.

Workshops

There are a number of interesting workshops being run by companies to highlight what innovative analysis they are doing. There seems to be a clusters of workshops around 3D laser scanning, UAV’s and Business Information Modeling (BIM).  There is also a strand that focuses on professional development.

Content

Content for GoGeo and perhaps even ShareGeo.  So that means news articles, blog posts and so on for  GoGeo.  With ShareGeo it would be great to get some sample data from some companies so that lecturers could use this in their lessons.  I will be looking to convince some of the UAV and scanning companies to give some data with ShareGeo.  If you don’t know what ShareGeo is, it is a repository for open geo-spatial data that enhances teaching, learning and research.

So if you already have a ticket I might see you there. If you don’t have a ticket, there is still time and there are special rates for students (£25 per day if you pre-book).  Students, do your research on the companies attending and speak to people to find out what they do, it is a great opportunity to see the diverse range of jobs that is available in the GI market.

GISRUK 2014

Jane Drummond opened the 22nd conference and explained that Pink was the colour of the conference, hence the helpers were wearing Pink T-shirts. This also might explain the pink umbrellas last time GISRUK visited Glasgow.

Wednesday

Mike Worboys keynote gave “A Theoretician’s eye view of GIS Research”. He highlighted the dramatic fall in the proportion of GISRUK papers that covered the theoretical side of GIS. He mused that perhaps we had covered it all; in the end he highlighted several areas where there was still much theory to be discussed, including Geo-Semantics and Geo-Linguistics.

In The Urban Environment session chaired by Peter Halls we saw William Mackaness talk about Spacebook, a system of delivering directions via audio as users encountered various way points on a route. The research found that using Landmarks gave better results than street names in terms of getting someone from A to B.

Phil Bartie, who was a researcher on William Mackness’s paper delved deeper into the issue of Landmarks. He was using images to find out what people identified as landmarks and was analysing them semantically and spatially to distinguish related and unrelated features. His use of Trigrams, or groups of three words may well be a solution to issues with obtaining good search results from EDINA’s place name gazetteer.

Nick Malleson was next talking about using tweets as a proxy for ambient population. Despite the issues with the quality and bias of the Twitter data he found that it still overcame the problems of using census data for city centre population when assessing crime rate. The peaks seen in crime rate for the main shopping and socialising areas disappeared as they were adjusted for the number of people present rather than the number actually living there. Outside of these areas, crime rates were still high in areas where there were social problems as shown by using census data.

The use of Twitter in research continues to raise interesting questions about sampling validity and ethics, this would continue into the second day.

Thursday

Thursday as the only full day in this years GISRUK program and had 3 parallel sessions.

Spatial Analysis: the best 2 talks being really quite different. Georgios Maniatis discussed error quantification and constraints in environmental sensors.  Georgios’ was looking at sediment movement in rivers, using a local reference frame offered accuracy improvements but added further complications, not least that a significant portion of the signal travel time was through water. Given the small distance from transmitter to receiver, errors could quickly become significant.

The other talk that stood out looked at visualising active spaces of urban utility cyclists. This was given by Seraphim Alvanides on behalf of Godwin Yeboah. Their analysis clearly showed that in certain areas of Newcastle the cycle infrastructure was mis-aligned with where cyclists actually rode. Cyclists used more direct routes to get to work and were more likely to detour on the way home to do shopping or other leisure activities. The fact that the Newcastle Metro which is operated by Deutsche Bahn, do not allow cycles onto their trains. In Continental Europe they seem more amenable to such integration.

Citizen Survey: This session looked really interesting and Neil Harris (Newcastle Uni) kicked off with a very interesting description of a heterogeneous sensor infrastructure which used a schemaless approach.  They had effectively decided to avoid XML and used key value pairs instead.  By using HStore they were able to hook things up with Postgres/PostGIS. The advantage of this approach was that they could integrate new sensors into the D’base easily by just adding key values to the main list. Key values may be seen as old hat by many, but with HStore it gives quite a flexible solution. The work is part of the Science Central project and will effectively pulls together all possible data feeds for the  Science Central to use.

The other presentation of note was by Robin Lovelace (Leeds) who invited discussion around the merits of twitter data in research.  This was not about the ethics around whether users knew what data they were giving-up, but more about the pro’s and con’s of using the data at all.

  • Con – unregulated data, unfocused, loudest voice dominates
  • Pro – diverse, low cost, continuous, responsive

Using Twitter data may raise the following questions

  1. Who made it? – the public
  2. Who owns it? – Twitter

As the discussion progressed it was mentioned that we may be in a golden age for social data, at the moment lots of people are providing information through social media and the social media companies like twitter are allowing us to use the info for free. At some point either the public will realise what info they are providing and seek to limit it, or the government will perhaps do so, and social media companies (who trade on information about users) may restrict access to data or try to charge for it.  Interesting and thought provoking.  If you want to find out more, look at Robin’s presentation and download his code from Twitter to set up a Twitter Listener.

Remote Sensing – I used to do remote sensing so i thought i would go to this session and see what was new. It turns out that it didnt have a huge amount of remote sensing in it, but there was a couple of gems worth mentioning. First is the work that Jonny Huck (University of Lancashire) is doing with sensors.  Jonny presented Map.me at last years GISRUK and it was good to see this being used in other people’s research, but the sensor work took a different direction. Jonny made a low-cost (£400) pollution monitoring kit that also monitored VO2 flux of users. This allowed him to crudely calculate risk of pollution.  It was simple kit using motes , smart phones and some basic gis for visualisation. I found it quite refreshing to see a simple approach taking off the shelf kit and running simple experiments. This will hopefully lead to discussion, refinement and some really insightful science.

The other presentation that i enjoyed introduced Whitebox – a geospatial analysis toolkit created by John Lindsay. This is an open-source GIS package and i was stunned by how many tools it had., over 370 at the last count! Possibly most impressive was the Lidar processing tool which will happily open 16Gb of raw lidar point cloud and allow you to process it. I dont know of another open source package which handles lidar.  John likes to call Whitebox open-access rather than open-source. Whats the difference? Well when you open a module there is a “View Code” button. This will open the code that runs the module so that you can see how it works and what it does.

Whitebox is relatively unknown, but John hopes to push it more and the audience suggested using GitHub rather than google code repository and to work towards OSGeo incubation.  It does look good and i have already downloaded it. Oh, it is a Java app so is easy to get working on any platform.

Plenary – I enjoyed the sessions and found something interesting in each one, but the plenaries were a bit underwhelming. Most conferences use the plenaries to bring everyone together and then get the big cheese’s out to show-off cutting edge research or to inspire the audience. The Thursday plenary didn’t seem to do this.

Friday – i was not able to attend on friday, sorry.

gisrukOverall – the conference was well received and i found some of the talks really interesting.  I would have like to be inspired by a keynote at the plenary and I hope that GISRUK 2015 in Leeds will use the plenary to motivate the group to continue to do great GIS research. Thanks to the  local team for pulling the event together, it is never an easy task.  You even managed to get the weather sorted.

 

 

COBWEB Meets the Commissioner at GEO-X

Nicola Osborne, from the COBWEB project team, explaining all five Citizens Observatories projects to the European Commissioner for the Environment, Janez Poto�nik.

Last week members of the COBWEB Project team attended the GEO-X Plenary and Geneva Ministerial Summit event in Geneva, Switzerland. GEO, the Group on Earth Observation, who have held annual plenary meetings since the organisation was established in 2005. GEO-X marked a particularly significant milestone with participants looking forward to the next 10 years of activity across GEO and GEOSS(the Global Earth Observation System of Systems) .  COBWEB was therefore delighted to be invited to be part of the European Commission delegation at the GEO-X exhibition, and to be able to take up opportunities to give a Speakers Corner talk on the project, to speak at the Citizens’ Observatories side event, to speak at the AIP-6 Side Event, and to show posters at the OGC stand including both a poster and video which was shown in the European Commission Speakers Corner area.

Chris Higgins talks about COBWEB during the Citizens Observatories side event.

The project was well represented by members of the COBWEB team covering technical, organisational, stakeholder engagement and dissemination activities, which enabled very productive discussions and networking to take place throughout the week. COBWEB’s Architecture Implementation Pilot (AIP) -6 achievements in enabling single sign on access across the COBWEB access management federation triggered some great conversations for Andreas Matheus, Bart De Lathouwer and project coordinator Chris Higgins. This contribution to the wider GEO community was also acknowledged in a GEOSS showcase film shown as part of the Ministerial Summit.

COBWEB’s development and infrastructure was highlighted in Chris Higgins’ talk during the Citizens Observatories side event, with a particular call made to our fellow Observatories’ to discuss and collaborate around interoperability across the projects. Meanwhile our stakeholder engagement work to date, including collaborations with organisations such as Dyfi Woodlands, was the focus of our Speakers Corner talk by Jamie Williams.

Citizens Observatories emerged as a key consideration for future environmental policy making and the GEOSS representatives were keen to ensure interoperability and access to citizen science efforts in generating environmental data in the interests of local, regional and global efforts to ameliorate environmental impact. Citizens are key to the European Commission vision as articulated in HORIZON2020 and therefore the initial tranche of Citizen Observatory projects, of which COBWEB is one of five, are trailblazing the future shape of citizen involvement as stakeholder in environmental policy.

The COBWEB project was present at the European Commission exhibition area through a shared stand with all of the Citizens’ Observatories projects: COBWEB,Citi-Sense, WeSenseIt, Omniscientis, and Citclops. Three collaborative posters were created especially for this space, outlining all of the projects in more detail and highlighting areas of commonality across the projects. We were excited to meet GEO Plenary participants and fellow exhibitors throughout the week – with over 89 GEO member nations present this was a truly diverse group. However, the highlight of the exhibition was the visit to the stand on Friday 17th January byJanez Poto�nik, the European Commissioner for the Environment.  The image at the top of this article (taken by Stuart Wrigley from the WeSenseIt project) shows Nicola Osborne, from the COBWEB project team, explaining all five Citizens Observatories projects to the Commissioner.

For the team, the event also presented a wealth of opportunities to meet, learn from and exchange ideas with projects and organisations from across the world, and particularly to make connections to complementary activities funded by the European Union. It was a hugely useful week and we look forward to sharing more from the event, including our presentations, posters, and a brief video on the AIP-6 work showcased, over the following weeks.

Society of Young Publishers Conference 2013

Today I have been liveblogging – by invitation no less – at the Society of Young Publishers Conference 2013 in Oxford, and EDINA is proud to sponsor the event through my participation. The event in entitled “Life in Publishing: It’s more than just books (and Tumblr)“, it’s theme being the future of publishing into the digital (and the inspiration for the name coming from this Tumblr blog).

My notes from the day can be found over on the SYP blog, Press Forwardhttp://thesyp.org.uk/syp-conference-2013-liveblog/

You can also view tweets from the event on #SYPC13.

Anyone interested in data, app development, digital publishing or disruption should find something of interest in there… and for me it has been a fun and informative day! And if you have been at the conference and are interested in what EDINA does around publishing and publishers I would recommend taking a look at the UK LOCKSS Alliance, CLOCKSS,  The Keepers Registry, and The UK Access Management Federation.

FOSS4G – a developers review – part4

The 4th and final EDINA developers eye view of FOSS4G 2013.  This one is from Tim Urwin who is the Digimap Service Manager.  Tim has been working at EDINA pretty much from the start of it’s internet mapping adventure and has seen software and toolkits come and go.

Who are you?
My name is Tim and I’m the senior GI Engineer at EDINA in charge of the Data Team and I’m the Operation Service Manager for Digimap. My interest in attending FOSS4G centred around three key components of the Digimap Service: WMS Servers, WMTS options and Database, although I delegated most of the latter to Mike due timetable clashes.

What did you hope to get out of the event?
My aim was to catch up on the latest state and future options of current software used by EDINA services and to find out more about the various open source WMTS options available.

Top 3 things? (Ed – no trains Tim!)

 

  • Chris Tucker’s MapStory keynote was inspirational and well-presented and it is certainly a site I’ll be tracking to see where it heads.
  • Ben Henning’s key note on think before you act for cartography was quite thought provoking.
  • Paul Ramsey’s PostGIS Frenzy talk was as funny as it was informative, and I only caught the re-run. Lots of good information combined with useful tips. (Ed- Paul’s a star, there wasn’t enough room for everyone first time round so he kindly offered to repeat the talk)
  • Honourable mention must go to the Festival of the Spoke Nerd – very, very funny
What will you investigate further?
MapCache and MapProxy WMTS software to replace our existing tile caching option and catch up with all the presentations I couldn’t attend due to timetable clashes. (Ed – remember that all the talks (hopefully) will be available on the FOSS4G YouTube channel when we get them sorted and uploaded)
One closing thought is that it was heartening to see that despite all the professional headaches that Digimap has caused me over the years that our approach to and delivery of the service has been validated as several leading data supply agencies have very similar service architectures. Built with Open Source software at the core, although there with some proprietary components for certain tasks. The primary differences being in WMS and caching software options, although they’ll be closer aligned once we upgrade to a more modern tile caching platform. Now only if we could also have their hardware – they have significantly larger number of servers :)

Oh and as I wasn’t allowed this in my Top 3 – seeing 45108 running again after 16 years of hard work by its custodian group.

FOSS4G – a developers review part 2

Photo – Addy Pope

This is the second part of EDINA’s developer review of FOSS4G 2013.  This time it is Mike Gale who will be providing his opinion on what was presented.

Who are you:

Michael Gale – GIS Engineer / Member of the EDINA’s Data Team. My job is to essentially deal with the vast quantities of GIS data we utilise at EDINA. I translate, modify, split and twist the data we receive into types and formats that our services such as Digimap can then offer to our users. I heavily use the Swiss army knife – GIS command line tools of GDAL/OGR and additionally Safe FME, Shell Scripting, Python & PostGIS.

What you hoped to get out of the event?

To discover the latest and greatest ways to utilise the tools I already use. I was keen to evaluate what advances and benefits PostGIS 2.0 could offer – particularly with 3D data, LiDAR point clouds & pgRouting. Additionally I wanted to discover new ways of integrating Python into my workflows.
Top 3 things you saw at the event (not the food or beer….)

(1) Chris Tucker keynote – MapStory.org

MapStory.org is a new website that empowers a global user community to organise knowledge about the world spatially and temporally. It is essentially a social media platform where people can crowd source geospatial data and create “MapStories” with spatio-temporally enabled narratives. The best way to figure out what that all means is to check out the website!!

(2) Cartopy & Iris – Open Source Python Tools For Analysis and Visualisation – Dr Edward Campbell (Met Office)

Cartopy is a new python mapping library for the transformation and visualisation of geospatial vector and raster data. The library offers the ability for point, line, polygon and image transformations between projections and a way to visualise data with only a few snippets of python code. Iris is a python library that specifically deals with analysing and visualising meteorological and oceanographic datasets, particularly 3D and temporal data.

(3) LiDAR in PostgreSQL with Pointcloud – Paul Ramsey

PostGIS support for LiDAR data has been non-existent until now. Paul Ramsey has created a new spatial data type for PostGIS 2.0 that now offers the ability to import huge amounts of point cloud data, and additionally analyse the information with several new postgis functions. Pretty impressive.

(4) I’ll throw a comedy one in as well: “Up all night to get Mapping”: http://www.youtube.com/watch?v=_EEVYHUQlkU

Editors note: view at your own (ears) risk.

1 thing that you are definitely going to investigate further

The IRIS and Cartopy Python libraries.

Thanks Mike.  I hope to add another couple of review next week.  My overview, with links to as many reviews as i could find, can be found HERE

 

FOSS4G – a developers review part 1

Panos – Edina Developer

As well as being part of the Local organising committee, EDINA sent a number of developers to FOSS4G.  In the first of a series of guest posts we find out what the developers thought of the event and what they will be following up.

First up is Panos. Panos graduated with an MSc in GIS from Edinburgh University 3 years ago and has been working for the geo team at EDINA since.

Who am I and in what I am interested in?

I am Panos and work in EDINA as software engineer. I maintain a service called UK Data Service Support and I am working on a project an EU FP7 project called COBWEB which focuses on mobile GIS development and sensor data. As you can see from my background I am mainly interested on mobile development, GEOSERVER and sensor data frameworks. I managed to attend most of the presentations that have to do with these topics.

What was I expecting?

I was expecting to see some more alternative mobile development solutions from the ones we use here in EDINA (Openlayers, jquery mobile, phonegap) and some more applications on sensor web. I am quite happy that I discovered some new software such as 52North and the fact that other people developed their mobile app with a similar way to us. So, let’s take them one by one:

Mobile development:

  • Most of the projects focused around OpenLayers mobile/leaflet/jquery mobile/sencha touch and phonegap.  EDINA have used a similar blend of technologies in our mobile app, Fieldtip GB. There were many similarities in how they designed their apps, the feedback they received from users, the workflow they followed and the problems they had with touch events on different devices.
  • The outcome is that they would take a similar approach but they would perhaps try an alternative to phonegap.
  • One smart approach they had on visualizing lots of vector data on a small screen was to use MapProxy to merge raster and vector data to deliver a WMS.  The touch event of the users then searches for the closest feature and the app asks for the corresponding WFS returning information for the correct feature.

GEOSERVER:

  • Geoserver 2.4.0 has some new interesting features. The most interesting for me is a monitoring system for checking what kind of users are using the app and what kind of data they are accessing. It’s a nice solution for monitoring the use you have on GEOSERVER and there is even a GUI for it.  I plan to investigate how we might implement this in the UK Data Service Support.

Sensor Web:

  • Unfortunately, the work that has taken place on this is quite limited. It’s mainly about hydrology.
  • North52 (https://github.com/52North/) seems like a promising framework that can adapt to all different scenarios about sensor data. Some people have used for covering the scenario of if someone should go for hiking by considering factors such as birch pollen, meteorology and air quality. This may be useful for COBWEB.

Following up:

I’ll definitely try to investigate the new GEOSERVER functionality and 52North framework in order to see how I can benefit from them in my new projects. I’ll keep you posted with my progress. I would also like to say that these 3 presentations that I watched are not the only one that I found interesting. There are more that are equally interesting such as leaflet, geonode, ZOO project, cartoDB, iris project and cartopy.  You should be able to watch these through ELOGeo in a couple of weeks.

FOSS4G – after the dust settles

Olympics of Geo?

FOSS4G 2013 has been and gone. What can i say, it seemed to go well. It is is hard to tell when you are so involved in organising an event as you notice all the little things that didn’t quite go as intended and you tend to be trying to do a hundred things at the same time. Archaeogeek has written an excellent post about the event from an organisers point of view so i wont repeat that here. Highlights. There are so many to choose from, seeing 200 people make, and then wear, Robin Hood hat at the ice breaker or seeing delegates sitting cross-legged on the floor when all the seats and stairs had already been filled. But here are my top 3:

  • OpenLayers 3 showcase – OpenLayers is awesome and version 3 looks like it will reinforce OpenLayers place as one of the best open source web mapping out there.  New features include map rotation with tilt features “in the pipeline”.
  • QGIS 2.0 Dufour – Quantum GIS is dead, long live QGIS.  The latest version is slicker and packs more features than before. Download it now and start exploring it. You can see some of the cool stuff in this slideshare.
  • Paul Ramsey – the man behind PostGIS did more talks than anyone else, re-running one that was so popular that we couldn’t squeeze everyone in.  His closing Plenary was a call for us to become “open source citizens”.  Certainly one of the most inspirational presentations i have seen in a long time.
  • OK, so this makes it a top 4, but it is a worthy inclusion.  Arnulf Christl winning the Sol Katz award.  Long overdue and a true hero of the OSGeo world.

and the winner is…….

So what’s next?  Well, I hope to post a number of short “reviews” written by people who attended the event which will have their own top 3 lists.  We, the organisers, hope to make all the talks available through EloGeo so that anyone can see what was presented at FOSS4G.  In the meantime, you can scroll through the 4500 tweets from the event if you have the stamina.

FOSS4G 2014 will be held in Portland. Looking forward to it already, just have to work out how to get there……

Other write-ups of the event:

A big thanks to everyone who made this possible, all the LOC team, you know who you are, the volunteers and the staff at the East Midlands Conference Centre. 

FOSS4G 2013 – 5 reasons you should attend

FOSS4G is the annual conference for anyone interested in Free and Open Source Software 4 Geospatial.  FOSS4G 2013 will be held in Nottingham between the 17th and 21st September. So what makes FOSS4G so important and why should you attend?

  1. Network – FOSS4G is the biggest gathering of developers and users of open geospatial software.  There will be over 700 people at the conference. This includes the lead developers on some of the larger open source projects such as OpenLayers and QGIS.
  2. Learn – You’ll learn a lot in a very short period of time.  No matter what your knowledge of open source geo from beginner to expert coder/developer you will learn something new at FOSS4G.  There are workshops for all levels that you can sign up to.
  3. Inspiration – You will be inspired by some of the major names in GIS and data analysis. The list of keynote speakers includes Paul Ramsey (co-founder of PostGIS), Kate Chapman (Acting Director of humanitarian team at OpenStreetMap) and Ben Hennig (Worldmapper Project).  For a full list of Keynote speakers, please refer to the FOSS4G keynote page.
  4. Double the fun – Visit AGI GeoCommunity’13 at the same time. Yes, that’s right FOSS4G and AGI GeoCommunity are happening in the same venue on the same week. This was no accident. GeoCommunity is a great event and the FOSS4G organisers wanted to bring the two audiences together. GeoCommunity’13 runs from the 16th to the 18th September.
  5. Can you afford to miss it?  – What does this mean?  Well, the conference package is quite reasonable given the number and diversity of talks on offer.  £165 for a day pass or £435 for the whole event (3 days and the FOSS4G Gala Night).  FOSS4G was last in Europe back in 2010 and it might not be back until 2017 as it moves between continents. So, if you are based in Europe attending FOSS4G might not be as easy for a number of years.

So, there are 5 pretty good reasons to attend.  I am sure there are many other reasons to come along.  To find out everything that will be going on at FOSS4G please look at the conference website and follow the event on twitter through the #FOSS4G hashtag.

FOSS4G 2013 takes place between the 17th – 21st September 2013 and will be held at the East Midlands Conference Centre, which is situated on The University of Nottingham campus. 

Repository Fringe 2013 now open for registration – and social media participation!

This year I have the great honour of being Chairing Repository Fringe 2013 (#rfringe13), the annual unconference on all things repository related. There will be several posts appearing here over the coming months in the lead up to our three days (31st July – 2nd August 2013) of repository ideas and fun and that kicks off today as I’m excited to say that registration is now open!

Now, as my job title is Social Media Officer, you may be wondering about the connection between repositories and social media. However, I have been involved in the organisation of Repository Fringe for some years now both because of my own event amplifying skills (I wrote a book chapter on amplification of Repository Fringe 2009), but also because social media is increasingly important for link sharing, for scholarly discourse, for information discovery. That makes social media increasingly important for publications, for research impact and for the use and visibility of materials deposited in repositories of all flavours – see, for example Melissa Terra’s April 2012 post for the LSE Impact of Social Sciences’ blog on the impact of blogging and tweeting research papers ).

Repository Fringe also embodies many of the core social media values of enabling community participation and authorship. The event is designed by and for the repository community and everyone who registers (free of charge) is encouraged to participate at every level of the event, from organising, to presenting, to amplifying and, of course, socialising. For me this has always made each event an opportunity to use or try out social media with a really up-for-it community – who picked up and embraced Twitter early, are always keen to share their images, presentations and expertise; who surface new ideas and great new ways to use these technologies in their own professional contexts; and who always provide thoughtful questions and reflections on the ways in which repositories and social media can work together.

So, if you have an interest in repositories then please do register for this year’s event. And otherwise expect a few more posts on how we are using social media this year, why we have chosen to use the combination of social spaces we have, and what we have learned from this year’s event.
