There are many ways to use many different maps for Swiss travel. Everyone has there own preferences
If you choose the Swisstopo map that I linked, you get the official map of Switzerland from the Federal office:
<<"The Federal Office of Topography Swisstopo “measures” Switzerland. It surveys and documents the landscape and the underground, and produces high-quality ...">>
There is little need to comment on the high quality. It is famous. The map has many many layers available, providing much the kind of information available also on Google Earth. Google Earth does it for the world, not just Switzerland. And, it has a lot of available views. "Earth Engine" does the kind of data analysis available in the Swisstopo map. The 3D feature is excellent. Although versions for other browsers are promised, they do not seem to be available now.
I do not wish to use Chrome routinely, even though it is by now the most frequently used browser. Among other cogent reasons, Firefox is the only browser to my knowledge that acknowledges and uses the color space profile tagged on the image for my images, instead of automatically dumbing them down to "SRGB."
In order to check out the trail markings in Google Earth for this discussion, I downloaded Chrome, and tried to load Google Earth. I got error messages regarding security, possible due the WiFi service that I am on, and which I do not have time to resolve while I am on the road. So, I will guess, rather than state positively that:
The trail markings in the Swisstopo map follow the official Swiss convention, used for all of the "Wanderwege" - hiking trails. I do not think that Google Earth offers this useful feature. Can you tell me if it does?
On the map that I linked you may turn the hiking trails on and off, showing their useful official difficulty ranking, while displaying either the topographical map view or the aerial photography view.
So, views with trails marked ( or not) are available with one click. And, he trails layer maybe turned on or off. I don't know if this is possible for Google earth. Can you comment?
