Boskoi is a free app that creates an interactive, crowd-sourced map of the edible landscape. Users add and edit their own finds, populating a global map of fruits, vegetables and herbs formed collaboratively by foragers all over the world.
Baltimore has its own crowd-sourced map devoted to greening – the Baltimore Green Map, though it doesn’t operate quite at the specific level that Boskoi does. Speaking of maps, did you know that mapmakers of old used to invent streets and even entire towns as a copyright protection device? The idea being that you could prove some miscreant had done stolen your map with tracing paper when those imagined alleys and fantastical burgs popped up on their ripped-off product. So theoretically there’s lots of old maps floating around with these “false entries,” frustrating motorists and hikers who’ve held out against GPS. Someone should create an app to crowdsource this, and create a map of places that exist only on maps.
