Recently, a new group of applications in the field of navigation services has emerged. Turn-by-turn driving instructions, like those provided by in-vehicle navigation systems, are available via on-line services and wireless personal data assistants (PDAs), which access a remote database and routing software. In an in-vehicle navigation unit, the map database and the software to access and manipulate the database are installed on an in-vehicle computer dedicated to the navigation system. It provides turn-by-turn instructions to the driver and can provide a new route if the driver misses a turn or changes his destination. For the frequent navigation services user, such as a taxi driver, in-vehicle navigation systems provide a valuable service at the one-time cost of purchasing the equipment. For the occasional user, new services are emerging that provide the same functionality, but on a fee-for-transaction basis. These services allow the user to access a remote database and routing server using a PDA, or a home computer, so that the user does not have to be in his car to access navigation instructions. On-line and PDA navigation services provide quick, cost-effective answers to some familiar questions for the individual user, such as "How do I get to the airport?" For the business user, on-line services can provide a quick and easy test of the value of services, such as vehicle tracking, delivery scheduling, and tourist information. The access of such information using on-line services allows the database engine provider and on-line service provider to take the risk and expense of maintaining the system, leaving the business user to focus on its core business. The centralized location of the database and routing software also allows the user to access the most current version of the database, and to access databases of multiple cities with no extra software or equipment. This paper will describe the key technologies and business considerations required to make this kind of service work, from the database server to the on-line product development software tools. It will also describe the emerging market for such services.
