Casey was one of the areas I was talking about wanting to survey last year but it was already done before the construction fences were even taken down, street names and all (and a single GPS trace, now covered by dozens more). > Still a just a cleared area on the bing imagery, but I still would > have put it more recent than 10 years. Maybe 3 or 4? The Bing aerial imagery analyzer gives different results for different areas, youre right, some of the newer parts of gungahlin are only 3 years old, but the imagery around Tuggeranong which I quickly checked is showing as March 2001. > Bing and Nearmap both seemed well aligned, but Nearmap with far > superior imagery. In related news, NearMap are flying Canberra as I write this, so expect even more superior (and up-to-date) imagery online in the next couple of weeks, hopefully with a little more coverage of unmapped areas to go and explore. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
