“The Book of OpenStreetMap” by Steve Coast funded on Kickstarter
Steve Coast – the founder of OpenStreetMap, who is currently working at Telenav, decided to make a present for himself and for the whole community for the 10th anniversary of the launch of OSM project. He launched a kickstarter campaign were just got funded to write a book about OpenStreetMap. Steve says:
I’ve been noodling a long time about how to structure and write a book about OSM. I never wanted to write a book about how to use the project, there are many now available of those in any case. I’m more interested in the stories and the people. How the project got going, the twists and turns, the ‘ah-ha’ moments and so on.
Steve says that the book will be split roughly as 25% history and 75% interviews with key people through the projects history. He was trying to raise $5000. There are still 6 days to go and he’s already got almost $8000 from 170 people. Nice!
OpenStreetMap was started ten years ago in London by Stave, and ince then it’s exploded in to a global powerhouse of mapping data, approaching two million registered accounts. It is often called Wikipedia of mapping, due to the fact that it’s created by people from around the world who use phones, laptops, GPS devices and cameras to capture geospatial data and place it on a map.
How the chances of a White Christmas changed over the last 50 years?
Recently we share a map that shows the probability of your city to have a White Christmas. Guys from Rutgers Snow Lab decided to go one step further and check how have the chances for snowy Christmas changed since their childhood. They’ve used NOAA satellite images and run an analysis of how the U.S. snow extent during the week of Christmas has changed in the past 50 years.
The map above shows the change in the average number of days with snow between the 1990-2013 decades and the 1966-1989 decades for the week of Christmas (the most recent two decades of the time series minus the first two). Places where the ground was snow-covered up to 25% more frequently in recent decades are colored in shades of blue, and places that were snow-covered up to 25% less frequently are colored shades of brown.
In much of the country, the number of days with holiday snow on the ground has actually grown over the past several decades. But in a few regions like the Pacific Northwest, Montana, Nebraska, Alberta, Saskatchewan, and around the lower Great Lakes—it’s become much less common to see snow during Christmas. Of course the scientists emphasise, that analysis of a single winter week isn’t especially meaningful as an indicator of long-term climate change but still it’s cool to know that chances for White Christmas in most if the U.S. are higher… how about in Europe?
