In general most image providers try to get summer images but in alpine 
areas this can be difficult since the useful time frame is fairly short 
in the higher altitudes and late summer is often not the time with most 
stable good weatcher.

Many people mapping landcover and waterbodies in high mountain areas use 
select lower resolution imagery (i.e. Landsat) in addition to high 
resolution images from Bing/Mapbox for verification. 

In some parts of the Alps you have also local sources with aerial photos 
available which usually are from a much stricter time frame in 
summer/autumn.  As far as i know Andermatt is not included there
