Graffiti are a short-lived and polarising form of cultural heritage. The graffiti-focused research project INDIGO, funded by ÖAW, documents and digitally preserves (almost) every graffito created along Vienna’s Donaukanal, one of the world’s largest graffiti hotspots. A central aim of INDIGO is the creation of a georeferenced orthophoto for each graffito, which digitally geo-localizes the graffito in 3D space and facilitates the interpretation in a spatial context. The poster explains the “orthophoto” concept and details how INDIGO uses modern photogrammetric techniques to derive them automatically.
