Abstract [en]

In an existing process, Rapid 3D Mapping datasets are automatically generated and converted to a format suitable for simulators and mission support systems. However, this high level automation does not allow manual error fixes and the addition of important features to the map data. The aim of this thesis is to create a process that allows the editing of a number of R3DM tiles with an existing 3D modeling tool and, after editing, to propagate the changes to the lower levels of detail in the data. Two solutions for the propagation, a standard solution and an alternative, are presented in this thesis. The motivation behind the alternative solution is to keep the original geometry of the R3DM data to retain the good rendering performance which those data sets permit. To achieve this the new model will be added to the R3DM data at only the highest level of detail, and this model is then simplified before propagation to the lower levels of detail. The resulting procedure to fix errors and add new important features is very effective, and reduces the time required for users to edit the many levels of the R3DM data.
