Hi, I'm Brandon Cohen.
I love maps, and I build geospatial apps. I am the Co-Founder and Head of Data at CivilGrid, where we are building Google Maps for the Underground.
I've also built a few other map projects
Clean and Green Philly
I was the founding engineer for non-profit open source project to use vacant property mapping to prevent gun violence.
GnarMap
I built a map to view realtime snow depths and observations from NOAA.
OpenParkingMap
I built map to visualize the (over)supply of surface parking.
PhillyTrails
I built a map of running and biking trails in Philadelphia.
