He was mapping for a project at college. I had a short talk with him. The students in his class are spread all over town and researching the change that happens when small alleyways close. If I understood it correctly. Why aren’t the universities and colleges support their students in contributing to Open Street Maps? He said they gather all this data. And then nothing. It just sits at their homes and does nothing. I really hope he will check OSM out and will find it a satisfying way to share the data.
