<br />any changes made to the data base. This theory of one-time data entry greatly reduces the risk <br />of overlapping or incorrect data. <br /> <br />Additionally, this concept eliminates any necessity for transfer of data between the various <br />modules within the system, since a single data base concept is utilized throughout the software. <br /> <br />Geo-File Based Pl'ocessing - Many management decisions in public safety are based on location <br />of activity. In order to provide this capability in a comprehensive manner, the entire CMS <br />software utilizes a Geo-File. This mechanism describes the local area to the computer. It <br />provides for the verification of locations and for the determination of relationships between <br />locations. Part of this is achieved through the determination of various sub-areas within the <br />. jurisdiction in which the location is found. This feature allows a department to take advantage <br />of many timesaving and vital functions including the setting up of patrol areas, grids, and <br />defining within the system such features as beat plan, fire districts, fire hydrant locations, and <br />indexing such information as run cards. The eMS system allows for the entry of four types of <br />locations: <br /> <br />· Addresses <br />· Intersections <br />· Mid-Blocks (street between two land marks) <br />· Common Location <br /> <br />In the system, entry of one of the above location types provides cross street information, address <br />verification, and specified places such as parks, schools, businesses, etc. Not only can units be <br />dispatched faster and more accurately with such a system, but the caller can be prompted for <br />specific location information, which will result in quicker over-all response times as well as more <br />precise information for analysis. <br /> <br />By using a pre-formatted and precise me~hodology for location entry, it is possible for the system <br />to reduce the number of actions by the dispatcher since the number of selection screens are <br />minimized. This means that the dispatcher is assisted to the maximum extent with the minimum <br />of data entry. <br /> <br />If a valid Geo-File entry is not found for the location of a call for service, the operators have an <br />event location override function key available to allow for processing the call for service without <br />a "valid" location. This allows for the timely response by the department to emergencies when <br />location information is partial or imprecise. The location may then be corrected as required at <br />a later time. <br /> <br />Another feature of the Geo-File processing capability is the use of aliases for locations and <br />streets. Through the structure of this file, any number of aliases or abbreviations are allowed for <br />a location, or street, while relating all of these to the same physical location for use in <br />management reporting, investigations, and crime analysis. <br /> <br />3 <br />
