Abstract
The present invention includes a system and method for selecting a unique geographic feature, including a mobile device that uses position and orientation sensors to determine a user position and a user orientation. The mobile device is adapted for wireless communication with a database that houses or has access to data concerning geographic features, as well as processing and computing means for calculating specific geographic relations discussed in further detail below. The system of the present invention further includes means for selecting among those features that are topologically related to the polygon. These include means for defining the geometry of the polygon, means for filtering those features that should not be within the geometry of the polygon, and means for ranking those features within the polygon. The method of the present invention is operable in conjunction with the system through the system hardware and software.

10. A computer-implemented method for selecting a unique geographic feature, the method comprising the steps of:
-
inputting data representing a user position; inputting data representing a user orientation; defining a polygon in response to the user position data and the user orientation data; providing a set of geographic features coinciding with the polygon; filtering the set of geographic features to determine a unique geographic feature, including determining whether a selected geographic feature is selectable by the polygon. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24)
