Awesome way to create open data

The only app (as far as I’m aware!) that creates open data instead of ones where only certain groups can access it. It’s a really good app especially considering it’s run by a one person team with very limited funding. I hope more people will join Open Litter Map to create open litter map, contribute to Open Science and reduce pollution!
