Building a geographic database
Abstract:
A system receives output geographic information en masse from a server. The output geographic information corresponds to input geographic information provided to the server en masse. The system builds a database that indexes at least some of the output geographic information to at least some of the input geographic information, attempts to locate specific output geographic information in the database, and determines the specific output geographic information by calculation if the specific output geographic information cannot be located in the database.
