I would like to automatically number an electrical network as shown in the diagram below.
If the digitization direction of the features is correct, then I get the correct numbering. I used the NetworkTopologyCalculator and TopologyBuilder transformers to perform the automatic numbering.
If the direction is reversed, then the numbering is incorrect.
Is there a solution to this problem?
Thanks in advance.
The NetworkFlowOrientator will turn all the lines in the wrong direction, i.e. all flowing towards the transformer, once they’re all in the wrong direction you can use the orientor to switch the orientation of all lines and that should mean that all lines are away from the transformer.
Thank you very much ebygomm for your quick response. It works perfectly.
However, I need to change the polygon shp of the substations to a centroid point in order to use it as a destination in NetworkFlowOrientor.
