Runners are the greatest mappers in the world. They plan with maps and track their runs. As a result  they create as community wonderful heatmaps based on workout data.
Even top secret military areas are mapped in detail, because runners are everywhere connected.
There are some areas where it is difficult to be connected, but we can foresee this case by a special map: 10kmlauf.blogspot.de - Funklöcher in Nürnberg

We can imagine a lot more useful maps for runners. I prefer to live in areas with a wood nearby. This not always guaranteed as we can see in this map:

But wood isn't the only factor,  we need to keep an eye on what we eat. There nations which are less successful in choosing healthy food:

For running we need clean air. The quality of air we breath we can look up within this map:

For route planning and inspiration for running routes we can use open street maps like
10kmlauf.blogspot.com - Wanderreitkarte

Freedom of running is a basic human right, but you might be stopped f.e. borders, checkpoints, wars, police. So we need to know any obstacles like nationalgeographic.org - Police stops.

After a run we can watch our mapped trip as a film
