Image-based georeferenced urban context reconstruction in a BIM environment: the case of the Crotone Fortress

The potentialities of the use of the UAV survey as base for the generation of the context mesh are illustrated through the experiments on the case study, the Crotone Fortress, proposing two workflows for the importation of the triangulated model, maintaining its real geographical coordinates, in the Autodesk Revit environment through a Dynamo Visual Programming Script [VPL]. Starting from the georeferenced context of the photogrammetric mesh, nine federated BIM models were produced: four of the urban context, four of the detailed areas, and the architectural model of the fortress.
