bing has updated its coverage of Switzerland for the 2nd time this year over the last days, leaving just three larger areas uncovered with high resolution imagery.
Areas that now have coverage all of Graubünden (including the Engadina), substantial parts of the Ticino and Valais plus small additions in the canton Berne. For a number of Swiss tourists resorts the additions will over time result in substantially better coverage by OpenStreetMap and this will be a boon for their guests.
