open data, data nude - video
Last year at TED, I asked you to give me your data, put them on network, assuming that if you put the data on the web, government data, scientific data, community data, whatever they are, they will be reused on other people to do wonderful things in ways you would not even have imagine.
So today I am here again to show you a few hints to show that, in fact, there is a movement "open date" on the march, now around the world. The cry of "raw data now," I did do this to people in the auditorium, was heard all over the world. So we start the video.
Classical history, the first that many people have noted, happened in March when, on March 10th to be exact, shortly after TED, Paul Clarke, a member of the British government, wrote on a blog, "Oh, I own a bit 'raw data. Here they are, relate to incidents in cycling. " The Times Online has taken two days to make a map, a map of "Mashable", we call these objects "mash-up", a "mash-up, a user interface that allows you to explore and take a look to see if your route to get to work is at risk.
There are more data, control data traffic, once again, published by the British government, and since they put them using the standard linked data a user could then construct a map by simply clicking.
effective are these data? Well, back to 2008. Let's look at Zanesville, Ohio. Here is a map made by a lawyer, has designed the aqueduct, see what homes are, and what homes are connected to the water? And obtained, other sources of data, information showing which houses are occupied by white people. Well, he realized that there was a bit 'too much correlation between the houses occupied by whites and homes that had water, and even the judge was impressed. The judge was not impressed by the beauty of 10.9 million dollars. This is the power to take data from a source, other data from a different source, connect, and show the results of this correlation.
Let's look at some data from the United Kingdom now. These data are the British government, a completely independent site, Where my money go, that allows anyone to access and investigate thoroughly. You can investigate on a particular type of expense or you can analyze and compare different regions. This is what happens in the UK with government data.
Yes, absolutely you can do on this site. Here is a site that allows you to audit the accounts of the recovery costs in California. And taking an example at random, Long Beach, California, you can go to the site and look at the money spent on different things such as energy.
In fact, this is the graph of the number of databases and archives data.gov data.gov.uk. And I'm delighted to see how big the challenge between the United Kingdom and the United States in blue in red.
How can you use this stuff? Well, for example, if you have a quantity Data on the places you can take, from a zip code, which is like the ZIP + 4 digits for a specific group of houses, you can make one sheet, print sheet that has high specificity with regard to bus stops , that is very specific things in your vicinity.
A larger scale, this is a "mash-up" data that have been made public about the Afghan elections. Allows you to select your criteria to highlight the things you want to observe. The red circles are the polling stations, chosen according to your criteria. And then you can select other items on the map to see other factors as the level of risk. So, these were government figures. I also talked
of data generated by the community, which I edited. This map is the wiki, this is OpenStreetMap. Terrace Theater, which I just put on the map because it was not on the map before last year's TED. I'm not the only person who alters OpenStreetMap. Each "flash" on this display put together by ITO World exhibition of 2009 made an edit on OpenStreetMap. We turn a bit 'over the world during the same year. Each "flash" is a change. Someone somewhere in the world looks to OpenStreetMap, realizes that it can be improved. You can see that Europe is on fire on updates. Some places maybe not as they should.
Here it focus on Haiti. The map of Port-au-Prince in late 2009 was not like he could be, not as good as the map of California. Fortunately, just after the earthquake, GeoEye, a commercial company, has released satellite images with a license that allowed it to open-source community to use them. This is Gennnaio in accelerated time people change, this is the earthquake. Immediately after the earthquake, people from all over the world, mappers who wanted to help, and they could have looked at these pictures, they have made the map very quickly. Now magnify
on Port-au-Prince. In blue are the refugee camps that these volunteers have seen from above. So now we have, immediately, a Real-time map that shows where the refugee camps, and this has quickly become the best map to use if you are doing relief work in Port-au-Prince. This is attested by the fact that it is posted to this Garmin unit used by rescue teams.
And Haiti, there is a map showing the left side, the hospital, which is actually a hospital ship. This is a real time map showing blocked roads, damaged buildings, refugee camps. It shows things that are needed.
So, if you were involved in any way, I just want to say that whatever you did, you'll be screaming "raw data now," or if you have uploaded to government data or scientific online, I wanted to take this opportunity to thank you very much, and to emphasize that we have just begun. (Applause)
