Mobile geographic information system and method
First Claim
1. A mobile geographic information system comprising:
- a database containing geographic information including information related to a geographic feature and information relating to a first waypoint associated with the geographic feature; and
a mobile device in communication with the database, the mobile device having a controller communicable with the database and a position sensor for determining a user position associated with the mobile device;
wherein the controller is adapted to receive information denoting the user position and, in combination with the geographic information relating to the geographic feature and the first waypoint, the controller is further adapted to instruct the user as to a qualitative relative position of the mobile device and the geographic feature in response to a predetermined topological relationship between the user position and the first waypoint associated with the geographic feature.

Abstract
The present invention includes a mobile geographic information system and method. The method includes the steps of inputting data representing a user position, defining a first circularly spatially extended point (CSEP) about the user in response to the user position data, defining a first waypoint associated with a geographic feature, defining a second CSEP about the first waypoint, and providing a qualitative user position relative to the geographic feature in response to a predetermined topological relationship between the first CSEP and the second CSEP. The mobile geographic information system includes a database containing geographic information including information related to a geographic feature and information relating to a first waypoint associated with the geographic feature and a mobile device in communication with the database, wherein the mobile device includes a controller and a position sensor for determining a user position associated with the mobile device.

12. A computer-implemented method for providing geographic information comprising:
-
inputting data representing a user position; defining a first circular spatially extended point about the user in response to the user position data; defining a first waypoint associated with a geographic feature; defining a second circular spatially extended point about the first waypoint; and providing a qualitative user position relative to the geographic feature in response to a predetermined topological relationship between the first circular spatially extended point and the second circular spatially extended point. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
