Hi friends,
In case it might be useful to anyone - I worked with some UN
Population Division statistics recently, and in the process I
geocoded all the urban areas in the stats. I thought I could
release this enhanced database to the community, to give something
back for all the great free resources that I use in my daily life.
The data is here, and I have smacked a CC license on the database.
Many thanks for your generosity, however, in order to make the data
really usable by anyone anywhere in the world, please consider
releasing the data under a public domain waiver such as PDDL, or
better yet, CC0, especially since your data may have copyrightable
elements. CC0 is the most appropriate waiver for such data. CC
licenses are not appropriate for data, and are discouraged by CC
itself.
It is available for download in various formats, and I also created
an animation video clip, a kml-file and a nice looking map.
The data contains a database of large urban areas for the whole
world, 1950-2050.
