Sentence "Coordinate reference systems can also be used to define schematic coordinates as they are used in terms of screen coordinates" is unclear; probably means "Coordinate reference systems can also be user-defined screen coordinates, for instance to define schematic views of the network" Airy Magnien (talk) 10:18, 29 August 2016 (CEST)
