Interesting, the size of this map has been reduced from 3.06 GB (v3) to 2.28 GB (v4).
The rastermap version of Topo Switzerland v4 was reduced too, resulting in a rastermap with a much lower resolution than v3!
Time to do some tests...
I compared v4 against v3 and as expected: jpeg-compression is much higher in v4
V3

v4

I don't understand this trend to lower raster-map resolutions whereas the accepted SD cards are getting larger !?
