While they're a good idea, I think they're a little disingenuous.
The train/tram map artificially squeezes in the north of the city so it looks like
Broombridge and Bayside are equidistant from the city centre. Urban rail maps regularly do this for clarity but I think this one takes it a step too far.
The Frequent Services map considers a bus service to be frequent if its frequent at peak hours. Yes, it says this in the description so they're not hiding it but, again, it's a little disingenuous.
The local area maps look good. DCU has an odd 'You are here' pointer on the map which is odd but otherwise they're very good.
