Benefits Census Tiger

Sean writes: from http://www.usaservices.gov/events_news/documents/Transparency.pdf (page 10)

When OpenStreetMap came to the United States, the Census Bureau’s TIGER line street data were already available in the public domain. This provided a huge jump-start for OpenStreetMap and the team quickly began updating and correcting errors in the data. Now there is a resource with updated and more accurate TIGER data available for the public. This cost Census no additional resources and no additional budget. In addition, the data made available by OpenStreetMap has provided the foundation for several technology start-ups creating new jobs and innovation in the marketplace.

nice quote.

times atlas, osm and mapmaker

News in brief style post… I really should do these as a podcast….

The Times Atlas, a wonderful coffee table sized book, has a section about OpenStreetMap. Nice!

Google MapMaker is releasing the data made by people using their Map Maker service, only for non-commercial and private use. Could be very useful for humanitarian work.  Currently for Kenya. Mikel does a great comparison of OSM vs Map Maker.

Google StreetView has launched in the UK for a few areas….highlights include half the photo covered with chestnut leaves, and in Bradford, the car being pulled over by the police. Ed writes a funny post about publicity, spectacle and the press, after the story about a village chasing the G car out of their roads.

Cloudmade Dev Launch

Back from CloudMade launch in London. Richard gives a great summary of the entire evening.

Enjoyed talking to Juha Christensen, the chairman of CloudMade about business models, and my theory of disruptive industries and investments. Very generalised it’s this: If you invest in me, you won’t get a ROI from this investment, you will only get a ROI if you have invested in these other companies as well; if you do not invest in me, your investments in these other companies will suffer. Anyhow, Juha responded saying it could apply but only where there just the one value chain. CloudMade’s aim is creating a new value chain. So, a short term investment opportunity, nonetheless, but in the long term, this new value chain has to prosper. I may have to file it with my time travel theory until I speak with an expert!

(Still) looking forward to playing with the style editor – closed beta, but they are opening up accounts all the time. Steve Chilten asked a question about whether the xml files (needed for doing your own map) can be downloaded, and got a “no”. Not now anyhow. Wonder if people will reverse engineer it…

Back to making money, their plan is to charge / revenue share for heavy / corporate users, and adverts. Adverts are not that popular.

One idea could be for advertisers details to be imported into the osm database, and so the data will be shared and “given back”?

Overall, good evening, great to meet up with folks, old and new, and to see John’s MapMe.at all spruced up and running with some CloudMade tiles.

If anything, it’s these custom tiles which will be the big thing next year speaheaded by CM (my more general prediction for the industry would be in the realm of mobile stuff, and  we’ll see a follow model for personal geo information).

Haiti

Over the Christmas period I imported the road network for Haiti – many thanks to Haiti’s CNIGS (Centre National de l’Information Géo-Spatiale) and CartONG. It has pretty much all the regular roads, but there’s still quite a bit of work to do.

haiti openstreetmap jan 2009

Late last year, we met at the GeOng conference in Chambery, organised by CartOng.  It was about the role of geodata and GIS in humanitarian work & crisis response (we also had a tiny mapping party afterwards). At the time, there were people on the ground in Haiti working to get some good quality data to share with other organisations. There were a few sources, some quite detailed, with even the little farm tracks mapped but very poor quality and inaccurate (possibly traced from un-orthorectified imagery), others were good, but were unable to be released publicly.  Bernard from CartONG was out in Haiti during and after the conference and was key in giving us the data on behalf of the Centre National de l’Information Géo-Spatiale (CNIGS).

Yahoo Imagery covers the area quite well, however the hurricane has affected the area quite considerably:

That saying, there are residential roads and tracks that can be traced.  It would be good to incorporate affected areas, which roads are closed, and which ones have been opened.  ReliefWeb has a few good resources. Interestingly, the map of road conditions highlights the types of road conditions interpreted as practical information, “4×4 can only pass over bridge, trucks have to ford river”. This is exactly the type of information that the UNSDIT seeks to make it easy to record.

Topology needs checking and validating – the original data had plenty of gaps and overhangs – roads that didn’t join up with each other properly (spent a couple of days fixing most of these). There are a few things that need to checked and correct properly.

Northern Mappers Meetup, Sun 25, Leeds

Behind the recent formation of Talk-gb-thenorth OpenStreetMap mailing list for the North of England. There’s the first Northern Mappers Meet-up.

Meeting 3pm at Scarborough Hotel, Leeds on Sunday 25th Jan. Details on Leeds page,

With a lot more active users, interested people and mappers up north here, we’ve started this mailing list. A place to discuss local relevant issues, announce and plan events. We hope to start a few social / say trips out events around the region in the new year. All welcome to sign up!

Africa Online Maps Compared

Robert Soden has a nice blog post showing why international development organisations should use OpenStreetMap if they want the most current data. He looked at three African capital cities, in Zimbabwe, Somalia, and the Democratic Republic of the Congo.

For two our of the three, Mogadishu and Kinshasa, there is simply no contest – OpenStreetMap is way ahead of the others in both coverage and in the level of detail. OpenStreetMap and Google Maps are comparable in Harare. The data available through Microsoft’s Virtual Earth lagged way behind in all three

Nice to see that more and more organisations are seeing clear benefits and potential.

Robert follows up with plans to create a “GIS for Humanitarian Relief”, utilising OSM. They’ve a great idea of using Interns to do the mapping! Hopefully, we can work together with the OpenStreetMap Foundation, and build on existing work  and relationships.

GeOng 2008 Forum, UNSDIT & Open Data

Few weeks ago I spoke and helped run a workshop on OpenStreetMap and GPS utilization at the GeOng Conference, in Chambéry, France – organised by CartOng, on behalf of Mikel, who wasn’t able to attend. The forum was about the role of geodata and GIS in humanitarian work & crisis response. We also had a “pico” mapping party after the conference.

The conference’s language was in French, although pretty much all of the slides were in English. The conference website’s Agenda contains links to many presentations.

CartOng is an NGO based in Chambéry which “provides information management services through mapping and GIS to humanitarian relief organisations. It also promotes the use of geospatial data for managing displaced populations.” At the moment, they have someone out in the Haiti helping them in the field… more on this later.

The forum saw NGOs, commercial & open source companies, various agencies in the United Nations and universities come together. It was the first of it’s kind, and I think that everyone got a lot out of it. From the opening speech by the co-presidents:

The objective of GeOnG, organized by CartONG, with strong support of UNJLC is
at first and foremost to broaden the network of GIS specialists, information
managers of the Francophone community involved in emergency operations and
development. So that we get to know each other and learn from each other,
thereby facilitating future missions on the ground. We often talk of preparing for
disasters, but we must not forget that the fast provision of geodata is an
important factor for making an operation and rapid deployment successful.

At the risk of repeating ourselves and re-quoting the CNIG, sharing of information is particularly important to avoid duplication of efforts and minimize costs. To achieve this, political will and efforts of all partners must be in place. Efforts need to be made by working, through financial contributions and through making Geodata available, of course. This furthermore comprises sharing of contents to be made available to all, including tools and methods, while recognizing that some are already used in case of crises/emergencies.

There was a very real concern and interest in data sharing and making data open, which is one of the ways that OpenStreetMap can help with. When a crisis hits, the responders do not care about whether the data is open or not, they care if its useful and available. If necessary, they will “beg forgiveness” later. But whilst this is needed, doing this every time however could be wasteful, as each agency appears to be coming across the same problems: finding the data, managing it, putting it into the correct format, sharing it with others.

Another key theme for the two days was that of standardisation of data in a good useful format. In an emergency, knowing that a particular road is officially designated a “B-Road” is not that useful, what people want to know is “can I drive a truck down it?”. To address these concerns, the United Nation Spatial Data Infrastructure for Transport was devised. Devised by the UNJLC from the bottom up with the help of the actors in the field, it’s been designed to help address this.

The schema is open. I really think that OpenStreetMap can benefit from the work done here. For example, the weight classification and bridge classifications. Using the form shown above (which I also think is an excellent way to help people collect data with openstreetmap) – all forum participants went out for a “parcours” around the town, and were asked to map route condition and any obstacles. It was a useful practical exercise. The next day, we downloaded the data and showed it as kml in google earth, as part of a workshop, although we did have a powercut!

In Haiti, there is work going on to provide OSM with data with the UNSDIT format, which would be excellent. OpenRouteService is planned to be able to use the data from the OSM database to provide routing solutions for Haiti. More on this in the days to come. We are also talking about putting OSM on phones (maybe using GPSMid) to help navigate around in emergency areas – often phones are the only thing that works. Being able to text a message saying “at lat x lon y, the bridge is down” would be very useful – and you wouldn’t even need a GPS. It’s a great example of the ecosystem around open geographic data – these tools did not exist before open data became available, it’s a great feedback loop – more data = more uses = more users = more data (works if you subsitute “more” with “better” too).

The schema also works both ways, OSM contributors could also benefit by having regular use of the data, and benefit from useful classifications of features, should they choose to adopt them.

Interesting presentations included, the work of UNOSAT (pdf) with some very good cartography, and excellent examples of the type of outputs they do. Working with remote sensing to produce accurate and timely maps. Camptocamp showcased (pdf) a range of opensource gis solutions, and their products, including MapFish – which interestingly can use Google Gears to enable offline editing of vector data – very interesting. UNHCR’s geoportal (pdf) – here they touched upon another important issue – many of their users out in the field have slow internet speeds, or no connectivity. I think this is a real challenge for GIS and for OSM – to have offline capabilities with the ability to synchronise these with a central server. Overall a good conference, I think everyone got a lot out of it.

Afterwards, we went up into the mountains and stayed overnight in a “refuge”.

Beautiful views, clear skies, great company, singing and playing Uno in front of the fire, and drinking home made schnapps. I spent the remaining week in Lyon, Avignon and Annecy – doing some mapping and seeing the sights. Avignon’s map is looking a bit fuller now, especially around the Old Pope Place.

Great place to get lost wandering around the narrow streets – and the GPS worked suprisingly well in the narrow alleys.
