Free the Earth (data)
A really great little post on the importance of making data freely available (or at least with as few restrictions as possible). And the dangers inherent in treating data as intellectual property.
In particular this bit, quoted from a policy paper prepared by Athena Global:
It's impossible to put a value on all the earth observation data that the US government makes freely available. It is one of the undeniably good things they do and it's a shame that other countries do not do the same. Access to European remote sensing data, in particular, is a shambles (CNES Aviso data the notable exception).
