Problem:
User encounters a .NET crash, “System.ArgumentException: Item has already been added. Key in dictionary: ” Key being added: ” “, while attempting to generate TerraScan trajectories from LIDAR Source strips.
Unhandled Exception Generating Trajectories: Item has already been added
Probable Resolution #1:
We suspect corrupted entities on the layer in question. Create a new trajectory layer and try creating the trajectories to the new layer.
