Using "Arches" for mapping historical and cultural resources!

You can create simple online maps using free tools like Google's My Maps, but for serious collections of local landmarks, or historical/cultural resources, you'll need something more powerful, such as the custom platform that we built for Chicago Ancestors.  I recently came across the open source platform "Arches," popularized by a digital history project in Los Angeles, that provides powerful geodata management capabilities perfect for digital humanities projects.
