Mobile device and geographic information system background and summary of the related art
First Claim
1. A system for providing geographic information comprising:
- a database containing geographic information, 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 referenced by an origin, the controller adapted to retrieve the geographic information from the database based upon the first location, the controller further adapted to receive a thematic query from a user and provide a response to the thematic query by restricting the geographic information presented to the user by a theme defined by the thematic query, with the thematic query further including a thematic portion and a there geospatial portion that corresponds to a particular one of an object, geographical feature or location that intersects a pointing direction of the mobile device as such pointing direction relates to the origin, and the geographic information that is retrieved from the database pertains specifically to the particular one of the object, geographical feature or location that intersects such pointing direction of such mobile device.

Abstract
The present invention provides a system and mobile device for providing geographic information to a user. The system includes a mobile device that is wirelessly connected to a geographic database. The mobile device includes a plurality of sensors for determining a first location and a first direction. A controller is adapted to provide information requested based on local queries and distal queries. In addition, the controller can respond to thematic queries of each variety, wherein the database search is limited to objects, entities or features that fit within a selected theme. Finally, the controller is adapted to select and order query results based upon two- and three-dimensional query windows.

8. A system for providing geographic information comprising:
- a database containing geographic information, 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 referenced by an origin, the controller adapted to retrieve the geographic information from the database based upon the first location, the controller further adapted to receive a thematic query from a user and provide a response to the thematic query by restricting the geographic information presented to the user by a theme defined by the thematic query, wherein the mobile device includes a pitch sensor for determining a first angle usable by the controller to compute a first direction, further wherein the mobile device includes a yaw sensor for determining a second angle usable by the controller to compute the first direction, and wherein the controller is adapted to define a distal query window about the first location and the first direction, the distal query window definable by the standard deviation of the position sensor, the pitch sensor, and the yaw sensor.
