Dachflächen HamburgRoof surfaces Hamburg
This WFS dataset provides geodata on all roof surfaces in Hamburg, derived from the city's 3D building model. Each feature is classified by roof type, distinguishing categories such as roof, dormer roof, chimney, parapet, dormer window, terrace roof, canopy, and other roof details. The dataset is published by LGV Hamburg (Landesbetrieb Geoinformation und Vermessung) and offers a detailed geometric and thematic view of rooftop structures across the city, useful for planning, modeling, and analysis involving building roofs.Dieser Datensatz zeigt alle Dachflächen von Hamburg inklusive Dachart an. Es wird unterschieden in Dach, Gaubendach, Schornstein, Brüstung, Dachfenster, Terassendach, Vordach und Dachdetails. Die Datengrundlage ist das 3D-Stadtmodell.
