Mobile Interactive Campus Map

To create an interactive map for our company headquarter campus. The campus consists of 20 office buildings, 15 parking garages, and various amenities. This interactive map will:

1. Pinpoint your current location on the campus
2. Map should be detailed enough to show each building and all walking paths (not default Google maps view)
3. Provide locations and way to look up various campus amenities:  Retail outlets, PC repair clinic, fitness center, ATM, cafeterias, etc.
4. In-building map displaying conference rooms in all buildings and all floors.

We are targeting iOS devices, both iPhones and iPads.
