2002 Google Programming Contest Winner: "Daniel Egnor's Geographic Search. Daniel's project adds the ability to search for web pages within a particular geographic locale to traditional keyword searching. To accomplish this, Daniel converted street addresses found within a large corpus of documents to latitude-longitude-based coordinates using the freely available TIGER and FIPS data sources, and built a two-dimensional index of these coordinates. Daniel's system provides an interface that allows the user to augment a keyword search with the ability to restrict matches to within a certain radius of a specified address (useful for queries that are difficult to answer using just keyword searching, such as "find me all bookstores near my house"). We selected Daniel's project because it combined an interesting and useful idea with a clean and robust implementation."
