Re: [Talk-GB] OS 1:25K tracing
+1 Power lines is a good example. We have some that were added for Birmingham from the 1:25k which are no longer present. Its easy to fix but a task we needn't have to do if folks traced what they know is present still on the ground.

Re: [Talk-GB] OS DG Vanessa Lawrence on the Future of mapping
Robert, Well, don't downplay our capabilities quite so easily. If the OS wanted to set us a challenge to map something in the same detail and to the same accuracy they achieve I can be sue that within a short time it would be done. That's the nature of OSM. The wider point is of course that OSM isn't trying to outdo the OS, that's never been the intention. Our national mapping agency is a true national asset and I'd hate to think it would loose that status. Let them do what they do best and let us do the same. The two can happily co-exist and potentially benefit from each other in the long run. Haiti shows that OSM is adaptable and can meet even the wildest expectation, and it can do it both effectively and well. This is not something the OS is set up to do. Personally I feel we should shout out about Haiti, not to hit at the OS, but simply to show the world how fantastic the OSM project is. We don't really do enough corporate type promotion of ourselves.

Re: [Talk-GB] OS 1:25K tracing
+1, I think we should be printing off maps and using them during walks. Mark whats there, or not, with a highlighter pen. Havent used 1:25K maps yet, but I have compared them using google when a similar issue arose a couple of days ago. Its clear a huge amount of changes have happened and it would be stupid to simply trace. We can't trace over google/bing satelite imagery because contract/terms of use, but it is tempting use the google satellite images to check what can be traced from the 1:25K (still the chance google is out-of-date!). This doesn't appear to go against google's terms of use. Jason 2010/1/21 Steve Hill st...@nexusuk.org Since the out of copyright 1:25K maps appeared, there has been rather a lot of tracing going on.
