I know there are many GPS-based ski trail map apps out there for mobile phones, but I was wondering if people have attempted using custom-made Google My Maps as a free, perhaps better, alternative.
You can use the drawing tools within Google Maps to draw lines to designate slopes (with different colors to match the difficulty of the slopes) and put bubbles to designate restaurants, lodges, etc. Such map can be viewed as a layer in Google Maps for Mobile and can even be shared publicly. What I think is especially attractive about using Google Maps for ski trails is that you can put the trails overlay on top of the Google Maps satellite view, which I think will make the trail maps even more realistic than commercial apps, which do not have the satellite view feature. In addition, unlike commercial solutions that can only be used on one platform, these maps can be shared across the board (be it Windows Mobile, iPhone or Android) as long as Google Maps for Mobile can be run.
So, are there Google Maps-based ski trail maps already? If not, is it a bad idea to start making them?
