The project of the week is a fun way to get out and map something that
you might not map otherwise.
World Cup 2010 facilities in South Africa
Taking inspiration from the suggestion page we’re going to add more
sports facilities to the map. Ideally, you’ll live near the venues for
World Cup 2010 and be able to add the stadiums, surrounding roads and
points of interest. You’ll find starting points linked in the full
article.
In your area
But you don’t have to live in South Africa to contribute sports
facilities to OSM. Add a local baseball field, hockey rink, curling
rink or football pitch to the map. Hey, why not add a dozen of them?
