I reached out to the person making this great map of #BlackLivesMatter protests suggesting that they consider GH/GL for sharing the map data. They said they'd like to know more… I'm under the impression that they're a student.

I'm not a GIS data use "insider" & couldn't find any obviously great intros online. So after 15 minutes of searching, I thought maybe someone here has suggestions?
