I’ve been following the various projects that research the Holocaust through its geography, often using GIS. I’m most familiar with the work of Anne Knowles (video), connected in one part to the Spatial History project at Stanford. The US Holocaust Memorial Museum also maintains a collection of geographically-based exhibits.
Today I learned about a new site, Exploring the Vilnius Ghetto. The map interface is the standard organization framework to arrange geotagged media. Nicely designed.
