Book: Schwarzplan
(for more information look at the books website or directly buy it at epubli.de or amazon.de )
Do you know what a “Schwarzplan” is? In English it is called “figure-ground diagram” and is a map showing all built areas as black and everything else in white colour (including the background). Here is an example of such a map for the area of Paris.
From such a map you can gain insights into many different aspects of urban structures. So it is for example possible to recognize hints of the age of parts of the city, their kind of reignship, their history of development, suspected density and many more. Furthermore, figure-ground diagrams have an aesthetically appealing effect and strongly underline the differences between different cities when comparing them.
Up until now, there was no atlas focussing on this kind of map which was sad . This might be due to the fact that one would have to get costly data about the buildings for each city individually But thanks to the OpenStreetMap Project I can present to you the atlas of figure-ground diagrams, a book called:
“Schwarzplan” is an atlas displaying figure-ground plans of 70 different cities all over the world together with some basic statistical information about their populations and extent on 152 pages made out of high quality glossy paper.

What about the book, shouldn’t it be open source ?
Dear, gaspard!
Short answer: No.
Long answer: Since the license change (http://www.osmfoundation.org/wiki/License/We_Are_Changing_The_License) of the OpenStreetMap project to the ODbL (http://opendatacommons.org/licenses/odbl/) in the year 2012, the book is a “produced work” and may be licensed under any license. The database or means to reproduce the database used to produce such a “produced work” have to be open.
The data used for the book are unmodified buildings from the original OSM Database – so the original data is already freely available.
