A total of 20 hand-drawn maps by former Rostock professor Dr Hermann Teuchert have been made available online in the linguistic repository LinguRep of the German Language Atlas Research Centre at the University of Marburg. The maps show, among other things, the distribution of certain Low German terms for e.g. the wild berry, harvesting potatoes, the compartment in the barn or the rye harvest. Two base maps showing the territory of the Grand Duchies of Mecklenburg-Schwerin and Mecklenburg-Strelitz serve as the background for the word maps.
