toponymy

 Via a Maps Mania post on the topic of place names, we were introduced to an interesting interactive application that allows one to discover geospatial patterns for the naming conventions of human settlements. Like the in the source article, I wanted to illustrate something like the isogloss of the Speyer/Main or Apfel/Appel line (or plotting the different ways we identity navigable passages of mountains), but I couldn’t summon up something as geologically typological (a toponym is a place name and the study of their origin is called typology) for Germany to chart just now.
I’ll be sure to play around some more with “Places” when I do think of a regionalism to examine but for now here is the frequency and concentration of settlements with the prefix Bad (bath, a spa town) in their Ortsname (oikonym) in the top map and those incorporating –stadt (town) in the bottom. Data is beautiful.  Give it a try yourself and show us your cartographic handiwork.
