1. A method of assisting an operator at a computer aided dispatch (CAD) center of a public safety (PS) network with field dispatching or locating a PS person operating a mobile PS device having a global positioning satellite (GPS) sensor, the method comprising:
- visually displaying, by a PS server, a location indicator indicative of a last GPS location transmitted by the PS device, and received at the PS server, on a geographic information system (GIS) map at the PS server;
visually displaying, by the PS server, on the GIS map a timestamp indicating a last time that the displayed last GPS location of the PS device was transmitted for the displayed last GPS location of the PS device;
calculating, by the PS server, a level of confidence that the displayed last GPS location transmitted by the PS device is accurate and can be relied upon as a function of how much time has elapsed since the time indicated by the timestamp; and
visually displaying, by the PS server, on the GIS map a confidence indicator indicative of the calculated level of confidence that the displayed last GPS location transmitted by the PS device and displayed on the GIS map is accurate and can be relied upon.

Abstract
A computer aided dispatch (CAD) center operator can view a displayed location indicator indicative of a last location of a public safety (PS) device on a geographic information system (GIS) map, together with a displayed confidence indicator indicative of the likelihood that the displayed last location of the PS device is accurate, for use in dispatching a PS person to an incident scene, or locating the PS person.

10. A system for assisting an operator at a computer aided dispatch (CAD) center of a public safety (PS) network with field dispatching or locating a PS person operating a mobile PS device having a global positioning satellite (GPS) sensor, the system comprising:
-
a PS server operative for visually displaying a location indicator indicative of a last GPS location transmitted by the PS device, and received at the PS server, on a geographic information system (GIS) map at the PS server; the PS server being further operative for visually displaying on the GIS map a timestamp indicating a last time that the displayed last GPS signal of the PS device was transmitted for the displayed last GPS location of the PS device; the PS server being further operative for calculating a level of confidence that the displayed last GPS location transmitted by the PS device on the GIS map is accurate and can be relied upon as a function of how much time has elapsed since the time indicated by the timestamp; and the PS server being further operative for visually displaying on the GIS map a confidence indicator indicative of the calculated level of confidence that the displayed last GPS location transmitted by the PS device and displayed on the GIS map is accurate. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
