There's nothing like a good map to tell you everything from where you are to what presidential candidate people are most interested in. And it looks like cartography's new frontier is heading indoors to explore building interiors.
For instance, Google uses a rucksack contraption to create indoor maps of large venues like the British Museum in London. Apple is also getting in on the action with its "Indoor Survey App," which allows users to map interiors by "dropping points," CityMetric reports.
And while Google and Apple offer nice 2D maps, Harvard University and Redlands, CA-based SmarterBetterCities are taking it to the next level. They're working together to create 3D interior maps of Harvard's campus, using ESRI's arcGIS platform. [CityMetric]
