Abstract
An method and apparatus for simultaneously displaying a raster map and vectorized street information corresponding to a vehicle position is provided. The system extracts information from a plurality of databases, including a mobile position database, a raster database and a vector database. The database information is interrelated by common latitude and longitude information. A graphical user interface displays the information in a format easily understood a dispatcher.
Claims53
Apparatus for fleet management comprising:
- a first memory portion comprising a first value and a second value, said first value and said second value defining a mobile unit location for a mobile unit at a selected time;
- a second memory portion comprising raster map data, said raster map data defining a digitized representation of a selected geographical area;
- a third memory portion comprising street data, said street data defining said raster map in vector form;
- and
- a display comprising a first display segment, said first display segment comprising said digitized representation of said selected geographical area, said street data, and a user locatable mark, said user locatable mark defining said mobile unit position based upon said first value and said second value.
