At what entry steps in the workflow must I be attentive to the accuracy of defining the coordinate system information?
There are three major steps in a typical workflow to be concerned with accurately representing the coordinate system definition:
The initial creation of the OrthoPro project assigns the final definition of the coordinate system of the outputs to be produced
The selection of a photogrammetric project uses the project.csf file found in the csf folder of the project data location to define the photogrammetric data coordinate system (extreme care in checking this project.csf should be done as it may have been set wrongly or incompletely in the photogrammetric process)
The input of surface data to the workflow must be assigned the coordinate system the surface data was assigned when in was produced
