A method, apparatus and computer program product are described to provide geographically-related features and services based at least in part upon the data provided by a mapping database, such as by providing for selective communication with user devices in a manner dependent upon a mapping database. In the context of a method, the location of a user device is determined. The method also determines whether the location of the user device is within an inner zone or a proximity zone extending at least partially about the inner zone. The inner zone is defined to encompass a reference point. If the user device is within the inner zone, a message is caused to be transmitted to the user device. However, if the user device is in the proximity zone, a function is performed relative to the user device that differs from causing the message to be transmitted to the user device.
