That's exactly what I've been doing. However, I've noticed a varying amount of agreement between the imagery and traces I've taken over the years. Sometimes it's bang on, sometimes there's up to 5 metres of difference between the two. I realise this could be down to the traces being inaccurate, but I've seen places where the average of many tracks still doesn't quite match the imagery. If I get the chance I'll take some reference points around Guildford that are easily identified on the images to see how far they're out, if at all. If I do manage this, is there any way of using the information to reproject the images? -- Jonathan (Jonobennett) _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
