A new MacBook Battery

Saturday, December 1st, 2007

Last week, I called Apple Support to report problems I was having with my MacBook battery. The symptoms I reported were:

  • MacBook will occasionally turn off without warning when not plugged in

Which gets gradually worse over the course of a month until:

  • MacBook will turn off unless connected to an external power source
  • MacBook will not turn on unless connected to an external power source

Apple told me that this is a know problem with their batteries and that they would send out a new one. Sure enough, a few days later a new MacBook battery was sent to my office. In return, I have to send back my old one. I now have a shiny new battery:

So what I definitely would not recommend to all MacBook owners is phoning up your local Apple Store (020 7153 9000 in the UK), choosing the support option, describing the symptoms above and taking delivery of a new MacBook battery for the cost of a local phone call.

FOSS4G OpenStreetMap Slides

Sunday, September 30th, 2007

Incase you missed the talk, here are the slides:

To accompany the slides, here’s a condensed version:

Some guys with GPS units on vans donated their traces to some other guys who made a collaborative map. This was cool, so lots of people joined in, collecting lots of traces, making nice maps and writing software tools to edit the map. The project is now growing very quickly and a Foundation has been set up, which does things like fundraising and organising conferences.

The most valuable thing to OSM are the people. But people are often disparate and hard to organise. For OSM to work the people need to be motivated by incentives other than money. The people won’t do stuff unless its fun, they trust the organisation and they see the results of the hard work.

Geo-data in the UK is very good, but very expensive and is sold by the Ordnance Survey. OSM’s data is not as good as the OS’s data, but its free. As OSM’s data gets better, the OS’s data will get cheaper. When OSM’s data is good enough for 80% of uses, proprietary vendors will be forced to compete on a margin of 20% of use cases. This will lead to more innovations in the mapping industry and more price cuts.

Some people say that OSM’s data is crap. Others just get on with making free maps.

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.

OSM Mapping in Victoria – ‘Map as a party’

If you haven’t been to an OSM mapping party before, this is you opportunity to find out what open mapping is all about. Mapping parties began with the 2006 Isle of Wight workshop, when 30 OSM volunteers from across Europe descended on the Isle of Wight with the ambitious aim of mapping all of the island’s roads and footpaths in one weekend. 48 hours later, we had a pretty good free map of the island, and thanks to the dedication of local OSM volunteers, the map was soon completed.

The Isle of Wight party set the standard for OSM mapping parties and whilst there are no hard and fast rules about how to have a mapping party, we nearly always follow a similar plan.

Day 1 AM – Meet up in a local coffee shop/community centre (hopefully with WiFi), meet the mappers, decide which areas we will each be mapping, head out to map.

Day 1 Lunch – Meet up at a local pub/cafe, get some lunch, take a look at the mornings traces.

Day 1 PM – Head back out for an afternoon’s mapping.

Day 1 – Evening – Meet up at a local pub, before heading out to a restaurant.

Day 2 – Repeat Day 1

The emphasis really is on inclusiveness and having fun. Anyone who is interested in mapping, GIS, OpenSource, GPS and so on is welcome to come along to the party. OSM have a load of GPS units that we can lend out to people for the day and we will give full training – so even if you have never used a GPS before, you’ll be mapping in no time and once you start you’ll find it hard to stop. There are no rigid rules – you don’t have to map the way I think you should (in-fact one of the great things about mapping parties is hearing about other people’s mapping techniques) and you don’t have to map a particular neighborhood – its your free time that you are giving to OSM, so its up to you what you do with it.

OSM at FOSS4G

There’ll be a few OSMrs at FOSS4G – Mikel, Andrew and Corey will all be in attendance. I’m planning on doing some informal mapping on Monday 24th, so if you are interested in joining in, get in touch. Friday’s Code Sprint could also provide a good opportunity for some OSM hacking – it would be especially cool to talk to some other FOSS4G developers about integrating OSM data and software with with other FOSS tools – why include a shapefile of OSM data in the QGIS binaries for example?. There’s also the BOF sessions that could provide great opportunities.

Meet the mappers

So there’s a few ideas – if you want to meet up to talk about OSM, free data or anything else during the week in Victoria, drop me an email. If you wanted to attend but can’t make it, keep tuned to OMB and OpenGeoData – where I’ll be blogging more about the mapping party and the conference.

Isle Of Man Mapping – OSM is on the way

Sunday, August 12th, 2007

On the 1st and 2nd September, the Isle of Man is going to be hosting its first OpenStreetMap mapping party, organised by Dan Karran, who’s been blogging quite a bit about the event. Dan’s latest post highlights the impact that OpenStreetMap maps of the Isle of Man can have. Right now, the best map of the Isle Of Man that you can find on the internet is OpenStreetMap’s. Its not complete yet, but it could be with a couple of days of effort.

You can find more details about the weekend on the OpenStreetMap wiki. If you are interested in joining in the mapping, get in touch with Dan, or me.

Geo-data for Kinshasa, Democratic Republic of the Congo

Monday, July 9th, 2007

Its quite hard to find geodata for Africa. OpenStreetMap have some bits and pieces:


Kinshasa, DRC

I’ve produced these shapefiles that contain vector data for Kinshasa. You probably won’t find this data in other places. It is licensed under the terms of this license – if you distribute this data, you should attribute its creators (OSM) and you should maintain its license.

Where2.0 Post Mortem – GeoCommons, Streetview, Virtual Earth, Yahoo!

Tuesday, June 5th, 2007

I got back to London from San Francisco yesterday morning after a week of geo-intensity; Where2.0, meeting a load of geo people, an earthquake and WhereCamp. This was the first time I’d been to Where2.0 – in previous years I listened to talks on the excellent IT Conversations as well as various illicit podcastings. So I was pretty excited to be taking part. There was a stark contrast between the really interesting stuff and the kind of interesting stuff being talked about. Companies like Google, Yahoo and Microsoft, who have contributed massively to recent developments in the geo sphere, just didn’t have that much to say. Google’s presentation focused on StreetView, which is nice but not-that-amazing, Microsoft showed us some very impressive looking shots from Virtual Earth, which is nothing new, and Yahoo! talked about Pipes and mentioned their involvement with OSM. Meanwhile, Sean Gorman (founder of Fortius One) gave a lightening talk about their new service, Geo Commons. ESRI weren’t there. They should have been.

Geo Commons is to desktop GIS what Google Docs is to Office suites. The site lets you upload a dataset in Shapefile format (support for other formats is planned in the near future), to which you add a description and tags. Through a slick drag and drop interface, you choose the fields that you want to display, before creating a heat-map using the GeoIQ (also by Fortius One) web API – a service that is well worth playing around with. If it wasn’t for the need to work to pay my rent, I’d by making heat maps all day long.


Cancer Death Rates in the US

With GeoCommons, Fortius One have captured 70% of the most fequently used functionality of desktop GIS. As the site matures, we can expect to see them capturing 90%. You don’t need to pay a huge license fee, or have a degree in GIS to start making meaningful maps any more. If I were ESRI or Mapinfo, I’d be worried. I’d opensource or my main Desktop GIS (which in the case of ESRI Arc-Map is just a shell), or at least start making it available freely and then sell custom plugins and extensions (things like Spatial Analyst, or Network Analyst) to the people who need it. If they don’t, their safe customers will start to look elsewhere for free alternatives.

What’s even better, is that the Fortius One team really understand what matters. Free beer. The emerging gap between the incumbents and the neo-geographic newcommers was superbly displayed during the Open geo-data BOF hosted by GeoCommons, who provided a kit-bag rammed full of free beer. We were still talking an hour into our one hour slot and got turfed out by Microsoft, who had the room booked for their “exploring Virtual Earth” BOF. Geo-Commons’ free beer was countered by the bar that Microsoft set up outside the room they were holding the session in, which came along with a MS employee whose job was to guard their beer. You can only drink from the teet of Microsoft if you sit through their entire session. Meanwhile, the neo-geographers who included GeoCommons, OSM and ShapeWiki representatives shared their Free beer with passers by.

Some fun stuff – Multimap, OSM and Tiles

Wednesday, May 30th, 2007

Yep, its OSM tiles on Multimap. More info on Mcknut’s blog.

If bright flashing lights are more your thing, take a look at this animation of OSM tile requests:

Live Satellite Images

Wednesday, April 25th, 2007

The Free GeoTools blog links to a new USGS site that shows real-time images from one of the Landsat satellites. Yes, real time.

The images are extremely coarse, with each screen pixel measuring approximately 250m on the ground. When I looked this morning, the satellite that was being broadcast was somewhere over the Pacific. Still, this is pretty cool stuff. People quite often ask me whether its true that Google Earth Pro gives you live images. Thats obviously not so far fetched after all.

Singing from up high

Sunday, March 18th, 2007

Songbird is an open source project to develop a cross platform media player to rival proprietary offerings like Apple’s iTunes or… oh well I guess iTunes is the only proprietary media player worth a mention really. The good news is the is now a “developer’s” binary of Songbird 0.2.5 available from here, so you can now have the joy of Songbird without the misery of worrying about C compiler flags. I’ve tested it on Ubuntu and Mac OS X (Intel):

One of the cool things about songbird is its seamless integration with network resources – once point it at the URL of a site that has MP3s (or almost any other audio format imaginable) on it, you can easily subscribe to podcasts and feeds and effortlessly drag and drop remote media into your library. A short but comprehinsive screencast will tell you everything you need to get going. If you listen to music on your computer, check out songbird.
