It’s a small thing, but the ESRI world topographical map has Weardale in Teesdale and Teesdale in Weardale (north of England). The Wear and Tees are rivers, and the ‘dale’ suffix indicates their respective valleys. Makes you wonder what else is not correct on their map. Just an observation, though I did report it to ESRI over a year ago.
That’s an interesting error, and I’m surprised they didn’t correct it. An other reason for OpenStreetMap
