calculating state plane coordinates between 2 states.
I have always used local coordinates when referencing my surveys to pipeline stationing, but recently have started using state plane coordinates so that down the road if someone needs to know where we were looking at old survey reports would be able to locate the pipeline with more accuracy.
With that being said, What coordinate system would you use if the entry point is in Texas, drilling under the Sabine river with an exit point in Louisiana?
Thanks for your time.
