It's getting a bit technical for the newbies list, but the self-adjusting scale bar was introduced in OpenLayers 2.10 . The patch to include it in openstreetmap was pretty trivial: https://github.com/openstreetmap/openstreetmap-website/commit/624453948e4d69387793577a77b080a2ddca2858 The documentation suggests that it uses the horizontal size of the pixel in the middle of the screen, so I don't think it's Spherical Mercator specific. http://dev.openlayers.org/releases/OpenLayers-2.10/doc/apidocs/files/OpenLayers/Control/ScaleLine-js.html Like I said, further techy discussion would be better off on [email protected] Cheers, Andy _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
