This document discusses location-aware apps and hacking location data. It begins with some example photos showing current location and what's around. It then discusses oldest maps, current maps, and questions like where, here, around. It covers getting the current location through asking the user, sniffing the IP, and inferring location. It details the W3C geolocation API, IP sniffing, geocoding, reverse geocoding, and the Yahoo! GeoPlanet API. Finally it discusses some interesting hacks and apps that utilize augmented reality and location data.
