Neogeography and the AGI: ‘What’s neo-geography anyway?’

Friday, September 21st, 2007

The Association for Geographic Information (AGI) are a UK-centric trade association for the producers and consumers of geographic information and related hardware suppliers, software developers and consultants. They exist to promote the interests of their members, provide them with a forum for discussion, oversee professional development and organise events like this week’s annual conference, held in Stratford-upon-Avon, UK.

I was invited to talk about OSM and some of the neo-geographic development that ZXV undertake. The AGI conference is a lot like Where2.0 for people who use proprietary desktop GIS and all the trappings of the pre-Web2.0 era, something that the conference tried to address this year by the inclusion of several talks relating to neo-geography, and a conference theme: ‘Building a geo-community’.

It was a tough crowd. These are the guys for whom tagging, folksonomies and the democratisation of, well, almost anything is a scary idea. In a lot of ways talking to groups like this is what its all about – these are the people who use geographic information all day, everyday. Convincing an open software advocate of the benefits of open geodata is one thing, but selling the idea that a bunch of normal people without years of training and professional certification, can make a map that’s actually quite good, to a room full of people who have built their careers upon concept that they are the specialists, is quite a challenge. Its a challenge that I relish and I think the message is really getting across – there was a lot of interest in OpenStreetMap, open-geodata and neo-geography.

Neo-geography – it will never work

The criticisms leveled and OSM and neogeography were nothing new. The usual concerns about ‘how can a trust the data’ and ‘will it ever be complete’, were voiced, along with some misinformed comments from several of speakers and panelists, including David Maguire, VP ESRI UK and one gentleman who’s name I missed, sitting on the far right of the pannel. (I’d like to crowd source the name of the guy sitting on the far right of the panel during the debate on Thursday, so please leave his name as a comment).

Both of these delegates spun the line that the kind of pins-in-maps analysis that neo-geographers undertake is one thing, but if you want ‘proper’ geographic analysis, you of course need a ‘proper’ GIS. Spatatial analysis cannot, apparently be undertaken with open source tools and is certainly outside of the realms of neo-geography. Have these guys not heard of GeoCommons?. ‘They must have heard of PostGIS or GRASS?’, I thought. Of course they have – these guys are board level executives of companies like Oracle and ESRI. Right now, it would be insane for the VP of ESRI to stand up at the AGI and tell the delegates that yes, its true, 90% of the users of ESRI, could actually use QGIS quite happily. Its tantamount to Vanessa Lawrence standing up and telling everyone to use OpenStreetMap maps. These guys are going to keep on peddling their company line, but that doesn’t necessarily mean they don’t understand what’s going on.

Oracle will profess that open source databases are no threat, but they they’ll release a free version. The OS will innovate to keep up with developments driven by the open source and neo-geographic community. And I would be surprised if ESRI don’t release a free desktop GIS that has equivalent functionality to QGIS. The smart guys are already doing so.

This is far from all I’ve got to say about the conceptions of the established GIS community regarding neo-geograhpy.

Awesome new traffic animations from Aaron Koblin and the Yahoo Design Innovation Team

Friday, August 31st, 2007

I blogged about Aaron’s flight path animations a while back. In June this year, I met Aaron and some of the other guys from the Yahoo Design Innovation Team at WhereCamp, who were showing off their animations. One that I particularly liked pulled data from the Yahoo! traffic API and created a frantic visualisation of accidents accross the US.

Whilst thinking of some cool stuff to do with the eCourier.co.uk GPS API this afternoon, I emailed Aaron to see if they had released their traffic animation. And they had – just this afternoon.

So here it is:

I can haz justice – Suing your landlord for fun and profit. Part 1

Saturday, August 18th, 2007

In Septmber 2005 I moved into a flat at 50 Maple Street, London:

Regent 2000 Properties – find your dream home

I was about to start a Masters degree course at UCL, which is just accross the road. I was an undergraduate student in London between 2000 and 2003, but from 2003 to 2005 I had worked and lived in East Africa, Ireland and Leeds. In September 2005, I had just enough time and money to spare two days to find a flat in London.

Finding a flat in London, on a student budget is not easy. I had up to £500 per month to spend on accomodation and travel costs, which really doesn’t buy you that much. To make matters worse, September is probably the worst possible time to try to find a new flat in London, as the influx of students ramp up demand. On the second day of looking, I walked into the offices of Regent 2000 Properties Ltd, in Camden. I was greeted by the Director of Regent 2000 Properties, a Mr Fahmy Elgamal, who performed a fantastic peiec e of Estate craft / am dram, and told me that I was ‘just in time’ to let one of their ‘best properties’ – a two floor flat at 50 Maple Street.

Shabby but cheap

The flat at Maple Street was shabby and poorly maintained, but it was available, very close to the university and above all, it was cheap. When I say cheap, I mean that I was to pay around £100 per week for a 3.5m*2m room, in a 4 bedroom, one bathroom, one kitchen house. There was no living room, but you rarely find a place in London for £100 per week, including travel costs that has one.

So we singed the contract, transferred the £2000 odd deposit (one months rent between 4 people) and I got back onto the train to Leeds.

October 2005 – the leaking begins

Everything that follows, was submitted to the Central London County Court on the 22nd June 2007. I have changed to names of the people I lived with to protect their identities. I have not changed any other details. My full statement to the Court can be found here.

On the 16th October, the leaking began. Water leaked from the roof, down the kitchen wall for days at a time. I phoned, emailed and wrote to the Landlord repeatedly, and they eventually sent a workman around. This is an exceprt from a document I prepared for the Court:

After phoning Regent 2000 Properties, the letting agents who deal with the letting and maintenance of the property, several times they had not sent any representatives to inspect or repair the leak. On Thursday 20th October 2005, I sent an email to Regent 2000 Properties stating:



“With regards to the water that is dripping down the wall – it is now dripping at a rate of one pint per 2.5 hours. Again, I am not trying to irritate you or anger you by telling you this. I have a legal duty as a [t]ennant to inform the landlord of such matters immediately. I have a family background in building surveying and water like this can cause permanent structural damage.”



By Saturday 22nd October 2005, Regent 2000 claimed to have repaired the leaking roof. However, there was now a growth of fungus in the area circled in blue on the sketch floor plan. Over the next few weeks the entire west wall of the kitchen became more and more increasingly damp, a fowl smell developed in the kitchen and the fungus began to decompose, which attracted flies.



This is documented in an email from Nicholas Black to Regent 2000 Properties, sent on the 22nd November 2005:



“Due to the leaking water almost a month ago there are dead mushrooms rotting in our kitchen, above the only shelves we have to keep food on. As you have so far failed to take action about this, we have contacted Camden Council with our concerns.”

This was the course of things for the next 6 months. Water would leak through the ceiling, I would complain, I would be ignored. Eventually a workman would come – often after I had waiting at the flat for hours with no one turning up. When they arrived, the workmen usually couldn’t speak enough English for me to be able to explain the problem to them. They usually had no, or very few tools, and they never managed to stop the water from leaking from the ceiling.

A wet start to the New Year

After a wet January, the kitchen ceiling collapsed on the 8th February 2006, showering an assortment of rotten plaster, wood, insulation, fungus and water all over the kitchen. We were unable to cook or even to access the kitchen for several days. When workmen eventually turned up, some days later, they simply nailed new plasterboard onto the still-damp joists. A new water stain appeared on the ceiling within hours of the workers leaving.

Bear in mind that whilst all of this is going on, I am trying to study for a Masters Degree in Geographic Information Science – I am studying for 12+ hours a day and battling with my land lord at the same time.

Here is another excerpt from the document I prepared for the Court:

My concerns about the inadequacies of the repair to the kitchen were confirmed on the 25th February 2006, when water leaking into the kitchen caused a light bulb to burn out. The incident is documented in the following email, sent by Nicholas Black to Regent 2000 Properties on the 26th February 2006:



“Last night leaking water caused the light bulb in the kitchen to burn out, leaving exposed live electric wires. This is an extremely dangerous situation as there is the potential for water to leak over exposed live electric cables. We can also not use the kitchen when it is dark as there is no light. Please send a qualified electrician to fix the problem and to determine the exact cause. “

Reading over the emails I sent and the document I prepared for the Court, its really hard to believe that this ever happened, but it did. By the end of February, water had been leaking down the kitchen wall for 4 months. The ceiling had collapsed once, mushrooms had grown, died, rotten and began to grow again. Now there was a live electric cable sticking out of the ceiling, with water dripping over it. Think it can’t get any worse, wait until the next installment.

Comming up next…

  • Health inspectors are called
  • My bedroom ceilling collapses
  • I file my case with the Court

Public Domain List of Tube stations

Thursday, August 16th, 2007

OpenStreetMap volunteers have just finished a Public Domain list of London Tube stations.

The list has been gathered by people using GPS units – so it is not a derivative of other OSM data. This means that it can be released under a Public Domain license, so you can do what you want with it.

I’ve knocked up a quick CSV of the data that you can grab from here

Update – To get hold of the data, visit the OSM wiki page.

A new modem, a new car and a new way of blogging

Wednesday, August 8th, 2007

An exciting day it truly is. I have just taken deliver of a T-Mobile Web and Walk USB 3G badass modem, which theoretically should mean near constant Internet connectivity. The whole experience of getting the modem has been relatively painless – I ordered it last Wednesday and it was delivered the next Saturday. Between Wednesday and Saturday I had prove my identity to T-Mobile – presumably the Electoral Register isn’t good enough. The unit itself is a sleek white Huwaei USB modem. Installation on and Intel Mac was easy enough and I was up and runing in around 5 minutes. For £29 per month you get unlimited (subject to reasonable use of 5GB, so not unlimited at all) internet usage but no VOIP/Skype. They don’t seem to block you from using Skype, but as you are ‘allowed’ to use Skype with teh £39 per month package, my guess is that they will up your subscription if they catch you using it.

Another breakthough has been signing up for Streetcar. I recently sold my car to some sucker and I am now carless. Streetcar is a car rental service thats been around for a coupe of years, but recently seem to have been on an advetising spree. The idea is that you register with them online, and then book cars on an hourly basis. Their VW Golfs are distributed around London, parked on the street. You turn up, enter a PIN and drive off – all for pretty reasonable rates.

The catch is that because my driving license is from the Isle of Man, I have to send in the usual torrent of proofs of identity. Someone at Streetcar has done their homework and figured out that finding a fax machin/photocopier is one step too far for the bussy or the lazy. To compensate for this, they offer you 5 hours free rental if you send in your documents within 7 days. Clever. Whats more, within 2 hours of signing up, I had a welcome call (to my mobile, a real person).

To whoever has invested in Streetcar – your money is being well spent.

5 Things you didn’t want to know

Friday, January 5th, 2007

Steve has ensured that I go for a mammoth 3 blog postings in one day, as I spread the 5 things you didn’t know meme:

  1. After graduating from UCL in 2003, I won a graduate scholarship with the British Institute in East Africa, a research body who conduct Archaeological, Historical and Geographic research in East Africa. I got the chance to work in Kenya, Uganda and Tanzania, and got my first exposure to sordid world of GIS and surveying, helping run mapping and surveying projects in Laikipia and Engaruka.
  2. I have a strange aversion to honey-comb and some other organic materials that have repeating patterns. The aversion is so servere that I have not been able to research the problem on the web for fear of seeing an image of a honey-comb
  3. I have always had an interest in music, playing the saxophone and piano and have experimented with electronic production, under the producer alias CubicSphere. More recently I’ve turned to Djing and organised a night last year.
  4. In 2002 I was the Treasurer of ARSE – The Association of Ramsay Street Enthusiasts – a ULU society that I started with the aim of diverting as much cash from the University of London’s coffers into my body via beer. The union were bankrupt that year due to administrative ineptness, so the project died. The Freshers Fayre was fun though.
  5. I have a long-standing problem with authority, which has always caused me trouble and has recently manifested into a tendency to argue with the police. They nearly always deserve it!

    I choose…

    Rich, Tom, Dan, Chippy and, err, thats it.

Flight Path Animations

Monday, December 4th, 2006

This site contains excellent animations based on US FAA flight data, as noted on the OSM mailing list over the weekend by Andrew.

They are QuickTime movies, so Linux users will need to install something like Mplayer and the mozilla-maplyer plugin to view them.

Isle of Man gets mapped

Tuesday, August 15th, 2006

First it was London, then the Isle of Wight, now the Isle of Man has got the SVG treatment: I’ll be back in the IoM after FOSS4G, probably around the 16th September, with the aim of doing a lot of mapping in a short space of time.
