The illustration at left shows a map the Paris Metro system (RATP).
The routes are depicted in a schematic view and this kind of map is challenging
to create because multiple routes may share the same path, for example multiple
bus routes along a single road or track. When this happens, the coincident
routes are offset in a fashion that makes it possible to understand the path
each route is taking. When using ArcMap and line features for the routes, the
coincident features draw on top of one another, making it difficult to
visualize. Read More...
