Showing the Hills

I grew up in a place with topography -- hills, valleys, winding roads, and all. But I moved to mostly flat Minnesota almost 30 years ago, and so when I travel I can be surprised when following a map on foot, only to find that it's all up hill (or seems that way).

So I love this idea:


Note that red, green, and blue are used to indicate severity of slope, and that the map also shows the varying quality levels of the walking paths. Very useful for people who are not as sure-footed as others.
