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.

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:

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.

Coming up in the next few weeks

Thursday, August 9th, 2007

There’s a shed load of awesome events coming up in the next few weeks.

This Saturday 11th August is the OpenSreetMap Third anniversary party, which is happening at 3pm at The Anchor pub, near London Bridge station. Click here for a map.

Next up, the 3rd – 6th September sees the 43d annual Society of Cartographers Summer School, which is being held in Portsmouth, UK. The summer school has a programme packed full of all things cartographic, with OSM represented by Artem and me, who are talking on Thursday 6th in the ‘Community Mapping’ session.

Also on the horizon are the Isle of Man Mapping Party – OSM’s first mapping party on the island on the 1st September, and then FOSS4G and the Victoria Mapping Party – more to come on both the Isle of Man and Victoria mapping parties in the next few days.

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.

The Future of Location Based Services

Monday, June 25th, 2007

Location Based Services (LBS) and Local Search (show me pizza places near here) have been going to be the next big thing for some time now. Some attribute the failure of LBS to the ‘walled gardens’ that mobile phone networks operate within, a factor magnified within the UK by the comparitively high cost of data calls compared to the US.

Local Search has been a lot more successful (if you define success as numbers of users), in that I can search for the nearest cashpoint to my current location and usually find what I am looking for. Critics of Local Search suggest that it will ‘never take off’ because people know what is in their area and don’t need the Internet to tell them.

There is some sense in both of these standpoints. The high cost of data calls, does diminish the value of mobile LBS for the consumer. I do where the nearest cashpoint to my house is. A problem with LBS is complexity: it seems to be difficuilt to to provide a service that tells me what I want to know about where I am. This complexity goes hand-in-hand with the walled gardens of the mobile operators – its in the best interests of a service provider to make their customers think the job they are doing is incredibly difficuilt – it adds value to their service.

The LBS question – what is there that I want, near where I am – isn’t a particularly complex one. We talked about some of this stuff at Where Camp a few weeks ago, and a load of smart people thought of some complex solutions to the problem. The solution isn’t a complex one. I know loads about cash points here, and I am happy to tell someone who wants to know about cashpoints here everything I know, on the same terms that I am happy to give my knowledge to Wikipedia – that is I want to have certain privacy guarantees and I want to be opt in and out of the participation process.

So, we lots of geographically dispersed people who may be willing to share their local/specialist knowledge with each other. Why not have a Twitter group for ‘here’, which you make friends with if you know about here? If I want to know about here, I send a Twitter to here, saying – ‘where is there a good bar near here?’. Here isn’t a real person, its a bot (a computer program) that listens to incoming Twitters via the Twitter API. When it hears my Twitter, it sends it back out to each of its friends – people who know about here. Pretty simple.

With this in mind, I was excited to hear about Multimap’s new Twitter Bot. You can now query Multimap’s location data by sending a Twitter to their bot who talks to their own API and replies, for example:


d multimap nearest postoffice to reigate

reply:

direct from multimap: 1. Reigate, Bell Street, Reigate and Banstead, RH27BB

This is the most innovative thing to happen to LBS for quite some time. Its simple, cheap, effective and it works.

Isle of Man is OpenStreetMap’s Image of the Week

Sunday, June 24th, 2007

Its great to see the the Isle of Man featuring as OpenStreetMap’s image of the week:

The map you see is the combined result of people tracing from aerial imagery, people collecting gps tracks, and people tracing from the map that the Isle of Man Department for Local Government and the Environment gave to OpenStreetMap.

With the help of Artem and John Burgess’ osm2pgsql conversion utility, I’ve produced some shapefiles of OSM data for the Isle of Man. Grab them from here.

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

State of the Map 2007 – Just days to go

Tuesday, May 29th, 2007

Incase you haven’t heard, the OpenStreetMap Foundation, who I sometimes mention in passing, are holding their first conference in Manchester on the 13th-15th July 2007. The line-up is looking fantastic, with an assortment of OSM regulars, as well as Google’s Ed Parsons and Multimap’s Sean Phelan, who’s combined experience spans light-years of the web mapping continuum.

So sign up and come join in the fun in Manchester. Whilst you’re there, subscribe to the SOTM07 feed to get the latest news and to hear the pre-conference podcasts.
