The document summarizes Christian Becker's presentation on linking spatial data from the web. It discusses Linked Data and the DBpedia project, which extracts structured data from Wikipedia and links it to other open datasets. DBpedia serves as a geospatial entrypoint, providing location data and links to additional information for over 328,000 places. Linked Data enables new applications and complex queries across domains by combining different open datasets.
