(Of course, Richard will tell me if I'm wrong, I'm sure :)) It sounds likely, though I'll look into it. David - could you give a lat/long for the area? Potlatch's approach is to faithfully use the Yahoo API, to stay on the right side of the legal agreement. The only tweaking it does is that it tries to automatically hide the Yahoo layer if all the tiles are blank, because presenting a first-time mapper with a load of tiles saying Sorry, there is no data for this area is pretty confusing. That does therefore, I'm afraid, preclude zooming in beyond what Yahoo offers, but the screen magnifier suggestion is a good one. cheers Richard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

On Windows, Mac and some distributions of Linux they are built in. On Windows, use the built-in screen magnifier in Programs Accessories Accessibility Magnifier (instructions: http://www.microsoft.com/windowsxp/using/accessibility/magnifierturnon.mspx) On Mac, simply use Ctrl-scroll wheel up to zoom in (you might have to enable a preference under the Trackpad tab of Keyboard Mouse Preferences to enable it). In Linux, use Orca in GNOME or KMagnifier in KDE (your distribution probably has a way to enable this through Accessibility Preferences). I have a Mac, and I do this all the time to make tracing Yahoo imagery more accurate. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Re: [OSM-talk] zoom yahoo data in potlatch?
You're right: that OAM imagery is very detailed. Unfortunately, it's not that good where I'm mapping. In Oakland, California, Yahoo! has two zoom levels beyond what Potlatch will display. It would be very helpful to me if Potlatch would display those zoom levels. Google has one (or two) more beyond Yahoo!
