Mapping: NASA’s Earth Observatory has put up a 4 MB high-res topographical image of Ireland. A rough calculation indicates that each pixel is under 0.1 of a mile on a side. It’s fantastic. ;)
Best of all, since NASA operate under the US’ enlightened copyright and licensing policies for government-funded data, it’s free — the masthead notes ‘Any and all materials published on the Earth Observatory are freely available for re-publication or re-use, except where copyright is indicated. We ask that NASA’s Earth Observatory be given credit for its original materials.’ Copyright is not indicated on this image as far as I can see. So go ahead and save a copy for future use, too.
