System and method for the selection of a unique geographic feature
First Claim
1. A mobile geographic information system comprising:
- a database containing geographic information including information related to a set of geographic features or a single geographic feature, the database accessible via a network connection; and
a mobile device connectable to the database from a remote location, the mobile device having a controller and a position sensor for determining a first location and an orientation sensor for determining a first direction, the first location and the first direction defining a polygon usable for selecting a unique geographic feature from the set of geographic features, with the mobile device being capable of being pointed at the unique geographic feature that is within or partially within the polygon and the system will specifically identify such unique geographic feature from among one or more other geographic features that form the set of geographic features that are at least partially within the polygon;
wherein the controller is adapted to retrieve the geographic information from the database based upon a predetermined coincidence of the polygon and the specifically identified unique geographic feature, the database being further adapted to employ at least a first filter for(i) determining whether a user can point at a geographic feature within the set of geographic features,(ii) determining whether a selected geographic feature bears a predetermined topological relationship to the polygon in combination with a user position to determine whether a user can be located in such a position to select the selected geographic feature, and(iii) determining whether a selected geographic feature bears a predetermined topological relationship to the polygon and if a selected geographic feature has other than a predetermined topological relationship to the polygon then a selected geographic filter will be excluded by the first filter.

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.

19. A mobile geographic information system comprising:
-
a database containing geographic information including information related to a set of geographic features or a single geographic feature, the database accessible via a network connection; and a mobile device connectable to the database from a remote location, the mobile device having a controller and a position sensor for determining a first location and an orientation sensor for determining a first direction, the first location and the first direction defining a polygon extending from a user into space, the polygon having a forward portion defining a geometric space containing a set of geometric features to which the user can point the device for selecting a unique geographic feature from the set of geographic features, and wherein the controller is adapted to retrieve the geographic information from the database based upon a predetermined coincidence of the polygon and a geographic feature, the database being further adapted to employ a first filter for (i) determining whether a user can point at a geographic feature within the set of geographic features, (ii) determining whether a selected geographic feature bears a predetermined topological relationship to the polygon in combination with a user position to determine whether a user can be located in such a position to select the selected geographic feature, and (iii) determining whether a selected geographic feature bears a predetermined topological relationship to the polygon and if a selected geographic feature has other than a predetermined topological relationship to the polygon then a selected geographic filter will be excluded by the first filter. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
