Abstract

A method computer aided dispatching. The present method includes providing a display 510 having a first display segment 530. The first display segment 530 includes a digitized representation of a selected area from a raster map, intelligent area data superimposed upon the selected area to provide intelligence, and a user locatable mark 520. The user locatable mark 520 defines a mobile unit position based upon a first value and a second value. The present method also includes using a dispatch system 811 operably coupled to the display. The dispatch system 811 includes order data from customers. A portion of the order data is transferred from a data acquisition 801, 808 device to the mobile unit 610.
