This is a collection of maps that I have made over the years on my own time. Contact me directly if you have any questions or if you want higher quality versions of these maps.
RAVEN (Risk Analysis of Vehicle and Environment Networks) is an interactive map that I built while working for Washington College. It is used by Law Enforcement, Traffic Safety Officials, and Local Governments in Maryland to visualize patterns of vehicle accidents and alcohol distribution. The map is not public and has not been released under an open source liscence. (Screen shot from the 2016 MHSO Annual Report)
