I’ve been playing around wth the geo tagging tool on Flickr which lets you drag an image onto a map and tag it with its geographical location. It uses Yahoo maps which seem to have much less detail than Google maps, certainly as far as Scotland is concerned.
If you take these two views of Glen Coe, the first was produced by Google Earth and the second with Yahoo maps on Flickr. Yahoo may be pretty good with cities etc. but I think Google wins hands down when it comes to more remote areas. I’ll certainly be adding more images to my Flickr account and geo tagging them.
