RIgeo.net - A Lab for Spatial Exploration of Historical Data

In the next step we deploy the GeoTWAIN (http://geotwain.uni-hd.de) and Nominatim (http://nominatim.openstreetmap.org) web services to geocode the place names. From this we calculate an average traveling distance to derive probable whereabouts of unknown places or places that do not exist anymore. This is done by calculating buffers on the point data and intersecting the buffers (see Figure 2). This narrows down the area for a manual search and additionally allows to geocode ambiguous place names cases where more than one result was received from the web services.
