An out of the box feature I would have wanted to see in Google Maps is topology information. Unfortunately, this is not something they provide. However, in the day and age of Internet mashups, surely there must be another service out there?
Sure enough, I came across http://www.theoutdoormap.com/. While this is decent and reminds me of looking up geographical information at a library back in college, you'd think there is some interactive service out there. If you have come across stunning services, feel free to share them in the comments section.
While on the topic of Map Mashups, the ProgrammableWeb website provides great pointers to useful resources: http://www.programmableweb.com/.
It contains pointers to very basic mashups such as "America's most unsafe Cities" to non-map related mashups such as "Movers 2.0", which is a service that shows web traffic trends.
