The GPDD is provided as a free resource to all those who wish to use it.
However the accumulation of nearly 5000 datasets has taken us and our collaborators many thousand of person-hours.
We would therefore like to know a little about you and the type of work for which you intend to use it. We use this information to see how our data and web site are used. We do not pass your details to anyone else.
Please tell us a little about the project you have in mind for the GPDD data.
