Summary
»Gefahrenerkundung Kampfmittelverdacht« (GEKV), a unit within Hamburg’s fire department, is in charge of classifying areas of potential concern related to remaining explosive ordnances from World War II. Our work is based on multi temporal analyses of historical aerial photographs and various historical documents. Currently, two projects are being implemented in order to continuously improve workflow and use information efficiently: a comprehensive orthophoto of Hamburg is being compiled and more than 3,000 terrestrial photographs are being added to our geodatabase.
