This document provides guidance on geocoding and extracting location information from text. It discusses using APIs from Yahoo to identify places, find details about places, and get geographical information. It also recommends tools like OpenStreetMap and Leaflet for mapping and the Yahoo GeoPlanet API for additional location data and interfaces. The document encourages exploring location-based hacks and links to resources for geocoding, reverse geocoding, and working with place data.
