PolicyMap PolicyMap is an online data and mapping tool that enables users to access data about communities and markets across the US. Use it for research, market studies, business planning, site selection, grant applications, and impact analysis. It is geared toward non-GIS experts who want to analyze large amounts of data quickly and produce maps, tables, charts, and reports. It also allows you to focus on analyzing data in the classroom - not collecting it or learning how to use mapping software.
