Google Maps
I generally consider services like Google Maps and the like to be fairly useful tools, especially for getting a feel of places you’re visiting for the first time. However, problems like this could be quite annoying:
The labels are in the wrong places, which is obviously an issue if you’re looking for either of those buildings. And they’re not obviously wrong (they haven’t labelled a field as the Theatre for example) so people are likely to follow them, and end up in some accommodation and the Physics building rather than the health centre and theatre respectively. I’m sure the problem isn’t isolated to the University of Exeter, but I couldn’t see any easy way to correct those problems.
