Hi Martijn, > I am wondering if you know of any more recent aerial imagery that may be > available? Or other suggestions to fill in these missing roads? (We have > found many, many cases in Canada alone)
We don't have a national mapping agency in Canada that gives everything away for free. Aerial imagery is typically carried out every couple of years by the provinces, but in agricultural areas only. This is not free and tends to cost anything from $10-150 / sq km just to see. Coverage is spotty, and depends on the province's priorities. Within 10 miles of the Great Lakes (so, not in your example) we used to have access to wonderful USGS imagery. We can no longer see it in Canada, although I suspect the images are still collected and may be geofenced. Can't have free data getting in the way of Provincial cost recovery, can we? cheers, Stewart _______________________________________________ Talk-ca mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-ca
