Welcome to the Justice Mapping Center (JMC) website. We specialize in using computer mapping—otherwise known as Geographic Information Systems or GIS—to help our partners better understand, evaluate, and communicate criminal justice and other social policy information. Our mapping studies are used by legislators, government agencies, research institutes, technical assistance providers, and the media. Explore our site to find out more about us and visit our Project Gallery to view some of our recent studies.
