OpenStreetMap 開放街圖
A friend sent this article about CalTopo: "Your Navigation Is Outdated. Here's How to Fix It."
於 2017年七月30日 由 apm-wa 以English發表。Interesting article came to my attention thanks to a friend–a discussion of tools and a product called CalTopo that seems rather intriguing–multilayer topographical maps of backwoods areas (I am a hiker when I can get back to the States). I’m wondering who out there in the OSM realm has experience with it, and what you think of it:

I’m well-aware of caltopo, and it’s pretty useful in the US where its default basemap shows forests, and where you have access to the impressive USGS topographical maps. In British Columbia, OSM is just so much better than the alternative maps (with some exceptions every now and then) that I usually don’t bother.
The slope angle feature is nifty, though as far as I know it doesn’t show run-out zones.
