摘要:
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.
