1. A method of displaying a user locatable mark representative of a vehicle position, wherein the magnitude of at least a first Value and a second value define said vehicle position, comprising the steps of:
- defining a first axis for said first value in a first segment of a display;
defining a second axis for said second value in said first segment of said display;
extracting data from a first database, said first database containing digitized information representative of a first predetermined area;
displaying a graphical representation of said digitized information adjacent to said first axis and said second axis to form a raster map of said first predetermined area;
extracting data from a second database, said second database containing mobile position data corresponding to said first value and said second value;
displaying said user locatable mark in said first display segment, said user locatable mark representative of said vehicle position during a predetermined time period;
extracting information from a third database, said third database containing vector information representative of said vehicle position in said first predetermined area; and
displaying vector text information corresponding to said first value and said second value of said user locatable mark, said vector text information being displayed on said second segment of said display.

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.

6. An integrated system for displaying a user locatable mark representative of a vehicle position on a raster map on a first display segment and vehicle position information on a second display segment, wherein the magnitude of at least a first value and a second value define said vehicle position, comprising:
-
means for simultaneously displaying a first display segment and a second display segment, the first display segment having a first and second axis, the first axis for said first value, the second axis for said second value, wherein a user locatable mark corresponding to the magnitude of said first value and said second value at a predetermined time period is displayed on the first display segment; a first database for storing digitized information representative of a first predetermined area; a second database for storing mobile data information indicative of said first value and said second value during a predetermined time interval; a third database containing vector information representative of said first display segment, a second display segment for displaying vector text information corresponding to said first value and said second value of the user locatable mark; and means for interrelating information from the first, second, and third database so that vehicle position information is displayed on a first raster display segment simultaneously with the corresponding vector text information. - View Dependent Claims (7, 8, 9, 10)
