The nice people of Public Geo Data have started a petition and a campaign for letters to be sent to ministers for the environment.
This is a quite important issue, especially in the these times of mash-ups everywhere. If the data — that has already been payed for by taxpayers — must be bought once more by every user, development in this area will be stuffed, and we won’t get to see the advantages that these types of information can bring.
I think you should too: Contact Your Minister.
