1. A system for communicating information to an operator associated with a calling telephone number, comprising:
- a computer workstation which includes a CRT display and means for operator input;
a map database accessible by the workstation containing a digitized map of the local area wherein each element of the map is associated with a pair of map coordinates;
a customer database accessible by the workstation made up of records, each containing a telephone number, associated textual information and a pair of map coordinates identifying a map location associated with the telephone number;
means for receiving a telephone number into the system;
means for generating a display at said workstation of the map stored in said map database wherein the displayed map is centered about the map coordinates associated with said received telephone number;
means for visually signifying the map coordinates of the received telephone number on the map display; and
,means for displaying the textual information associated with said received telephone number.

9. In a data processing system having means for operator input and graphics display, a method for displaying information associated with customer telephone numbers, comprising the steps of:
-
(a) receiving a telephone number which is then designated as the target telephone number; (b) displaying the target telephone number; (c) searching a customer database for a record containing the target telephone number, designated as the target record, wherein each record of the database contains a telephone number, a pair of map coordinates corresponding to a geographic location associated with the telephone number, and additional textual information associated with the telephone number; (d) displaying the textual information contained in the target record; (e) designating the map coordinates of the target record as the target map coordinates; (f) generating a display buffer containing visual display elements for passage to a graphics display routine by accessing a map database containing a two-dimensional array of visual display elements representing a map of the local area, wherein the display buffer is constructed so as to result in the generation of a map of the local area centered about the target map coordinates, the number of display elements of the map database used in generating the display buffer being in accordance with a preselected map scaling factor; (g) displaying a map of the local area by calling the graphics display routine with the generated display buffer, wherein the target map coordinates are visually signified; and
,(h) changing the target map coordinates in accordance with operator input and returning to step (e) to generate a new display buffer for displaying a map of the local area centered about the new target map coordinates, thereby allowing the operator to pan to selected areas of the display. - View Dependent Claims (10, 11)
