People and Geography Quiz

The purpose of this web mapping application is to understand how well people can define locations of different groups in geographic space, and how this relates to their attitudes about towards these groups. Using two simple datasets such as US block groups and US zip code, an US basemap by Esri, and a classic web survey approach, the application asks users to indicate in which neighborhood do most people from a certain group lives. A side-by-side mapping approach is used to retrieve feedback once the survey is completed.

Rusian Genealogy Map

The Rusian Genealogy Map is an attempt to render visually the dynastic connections made between the ruling family of Rus’ (the Volodimerovichi) and the rest of medieval European royalty in the eleventh and twelfth centuries. The information represented on the map comes from the Rusian Genealogical Database (genealogy.obdurodon.org) compiled by Christian Raffensperger, with technical assistance by David J. Birnbaum. Both projects highlight the extreme interconnectivity of Rus’ with the rest of medieval Europe and are part of a larger goal of reimagining medieval Europe.
