The background image of CERN maps has been updated to the most recent version. The new 2016 orthophoto provides information with a higher resolution of 5 cm/pixel (previously 20 cm/pixel). It is now a default background for CERN Map and GIS Portal. Photographs were taken in March/April 2016.
It is possible to browse through previous aerial images by expanding the "Photographies aériennes" on the navigation pane and adjusting the slider (as shown below).
If you can’t see the new orthophoto, please clear your browser's cache (press Shift+Ctrl+Del, then clear cached images and files).
