OpenStreetMap allows to add information relevant to local communities without necessarily having an economic incentive, unlike other mapping giants like Google.
One of our Transition-Waedenswil community gardens, the "Stadthausgarten", is now featured as well: https://www.openstreetmap.org/way/704507208. That's where we usually meet, and where we grow edible plants for all passers-by to savor.
Btw., the editing tutorials of #OpenStreetMap are very well made and a real pleasure to follow!
