It looks like some of the stuff in Canada is Public Domain: http://cumulus.cr.usgs.gov/dispatches/PRODUCT_Orthos.html#Canada - but it doesn't tell you the boundaries. It's newer than the Bing imagery where I live; looks like late summer 2009 or summer 2010, by the fresh(ish) paint on my deck.

But that list is not exhaustive; not every US county is on it. F'rinstance, in Missouri, Andrew, Buchanan, Bates, Benton, Pettis & Cooper counties aren't listed - so that could mean that any imagery there is not Public Domain. cheers, Stewart -- http://scruss.com/blog/ - 73 de VA3PID ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
Re: [Talk-ca] USGS Orthos in Canada
That's indeed some nice imagery. In the area I looked at, the QC/NY border south of Montreal, it doesn't extend all that far into Canada but it's nice nonetheless. If you look at the list linked from the wiki page ( http://cumulus.cr.usgs.gov/dispatches/PRODUCT_Orthos.html ) there don't seem to be any non-PD regions -- so I guess we can use it? Does anybody know how to load this data in JOSM? The URLs/instructions provided in the wiki article didn't work for me. Cheers, Harald. On Thu, Aug 9, 2012 at 8:17 AM, Stewart C.

[Talk-ca] USGS Orthos in Canada
While editing near Leamington ON in Potlatch, I clicked by accident on the Background -> "OSM US USGS Large Scale Aerial Imagery". It came up with really sharp and recent orthoimagery. It's of similar quality to the SWOOP images I buy at $50/km^2 for work, and covers some areas that Bing doesn't. Images look to be from 2010 or so, guessing from the visible wind power projects in SW Ontario. Trying out several areas near the US border I found: * that coverage is seemingly random; some isolated areas have it, contiguous areas near the border might not * it's coming from a very slow server which only works if you're zoomed in very close * it's not seemingly available from a public WMS, as any of the USGS servers I tried blank at the Canadian border. Surprisingly, it seems that not all USGS imagery is public domain (https://wiki.openstreetmap.org/wiki/USGS_High_Resolution_Orthoimagery#Data_License). So, can we use it? cheers, Stewart ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
