SYSTEM DESCRIPTION <br /> NR <br /> MapTrak: <br /> TRACKING UNITS <br /> FUNCTIONAL DESCRIPTION <br /> Initiate Tracking Units by choosing Dispatch on the MapTrak menu bar,then Track Unit from the <br /> Dispatch menu, (see page 1-4) or by choosing the Track Unit icon from the MapTrak Dispatch <br /> Toolbar(seepage 1-12). <br /> MapTrak provides you with the ability to track units displayed on the map through a connection <br /> with CAD.In order for MapTrak to update unit locations on the map,two CAD programs must be <br /> running simultaneously:the CAD Status Display and the AVL (Automatic Vehicle Locator)Inter- <br /> face. <br /> MapTrak updates the locations of units(as x,y coordinates) on the map via the CAD AVL Inter- <br /> face program. The AVL program tracks the location of specified AVL-enabled on-duty units via <br /> GPS technology and sends unit latitude/longitude coordinates to CAD via the CAD/AVL inter- <br /> face. CAD then updates unit locations each time the AVL program sends new coordinates for a <br /> unit.However, a unit location must move more than 300 feet for the system to recognize a loca- <br /> tion change. <br /> MapTrak allows you to configure the appearance of units selected for tracking.You can configure <br /> the appearance of these units in the Tracking Unit Attribute Editor window. (See page 1-78.) On <br /> the map display area,MapTrak displays the units as defined in the Tracking Unit Attribute Editor <br /> window. <br /> To stop tracking a unit,select the Track Unit icon on the Dispatch toolbar(see page 1-14)or select <br /> the Track Unit menu option from the Dispatch menu on the MapTrak menu bar(see page 1-6) <br /> MapTrak stops tracking the unit.The object attribute of the unit selected for tracking reverts to the <br /> original unit object attribute as shown on the unit object button in the Map Legend area(see <br /> page 1-98)of the MapTrak program window. <br /> 1-24 01/18/10 <br />
