Abstract

Das Vorhandensein von Wasserflächen im urbanen Raum wirkt sich positiv auf die Gesundheit und das Wohlbefinden der Menschen aus. Um diese Erkenntnis in Planungsprozessen zu berücksichtigen, ist eine Quantifizierung von Stadtblau notwendig. Als Stadtblau werden alle sichtbaren und erlebbaren urbanen Oberflächengewässer bezeichnet. Charakteristisch ist dabei die Lage der Gewässer im bebauten und besiedelten Raum. Durch die Ermittlung von Sichtbarkeiten werden Gebäude im Hinblick auf sichtbare Gewässer bewertet. Dieser Bericht stellt die Entwicklung eines Workflows dar, der auf der Grundlage eines 3D-Stadtmodells Sichtpunkte stockwerkspezifisch an Gebäuden generiert, anschließend eine Sichtbarkeitsanalyse durchführt und schließlich für jeden Sichtpunkt das sichtbare Stadtblau quantifiziert. Zur Visualisierung werden die Ergebnisse des sichtbaren Stadtblau von den Sichtpunkten auf die Gebäudefassade übertragen sowie das Stadtblau im Hinblick auf die Häufigkeit einer bestehenden Sichtbarkeit bewertet.

N2 - The availability of water surfaces in urban areas (urban blue space) has a positive effect on people’s health and well-being. To take this knowledge into account in planning processes, the urban blue space should be quantified. Urban blue space is defined as all visible and accessible water surfaces, with the intrinsic characteristic of being located in populated areas. To assess the visibility of urban blue spaces, individual buildings as well as parts of one building can be evaluated according to the relative visibility of the waters from these locations and vice versa. This report presents the evolution of a workflow to quantify the urban blue space. First, the workflow generates viewpoints on building surfaces by floor, based on a 3D city model. In the next step, a visibility analysis is performed and, finally, the visible urban blue space is quantified for each viewpoint. The quantification and its visualization are performed for both ends of the line of sight: the measure of visible urban blue spaces for each viewpoint is represented on the building facade and the visibility frequency from all viewpoints is evaluated for each part of urban blue space.
