Abstract
The invention provides a system for providing geographic information. The system includes a base unit that receives a request from a mobile unit and provides a response to the mobile unit. The request includes a point of interest category and a traveling distance or traveling time parameter. The base unit identifies a point of interest that matches the point of interest category and satisfies the traveling distance or traveling time parameter. The response from the base unit to the mobile unit provides the identified point of interest.
