personnel . Emergency Services personnel indicated that a mobile GIS data browser pilot m project with New World is being pursued and should be implemented shortly . However, the mobile browser does not have GPS or routing capabilities . Ideally, the mobile data browser should have GPS capabilities to show the location of the vehicle and routing capabilities to show the optimal route to an incident . The Department should also investigate equipping the Fire Rescue Boat with a mobile data browser in addition to required technology to run the browser since it currently does not exist on the boat. There are two methods for Emergency Services Department personnel to access map information in the field : 1 . Map Books 2 . Mobile Computers 1 . Map Books The most cost effective solution for access to spatial information in the field is via map books . Map books can be generated for all Emergency Services Department personnel . Each page can display a different section of the County. The location of all pertinent features , such as critical facilities and schools can be displayed on top of base map information , such as labeled streets, tax parcels, building footprints with addresses , and even aerial photography. Map books represent an effective means of referencing the location of all pertinent features . As features are changed or added , new map books can be generated to reflect these changes . Map books are currently being used by field personnel . The Database Manager in the 911 Database Section maintains and updates these map books using ArcGIS Software . The Department should continue to produce map books for field crews . These map books should contain up-to-date information and a variety of reference data . As pertinent GIS layers are created , GIS staff should ensure that new map books are created on a regular basis . One key issue that will be addressed with the Countywide GIS implementation is having a one stop shop for all county data such as the street centerline layer. Streets are added quite frequently, effectively rendering map books out of date . Consequently, the next option , mobile computers , should be considered as a viable alternative to map books . 2 . Mobile Computers A more advanced method for accessing spatial data in the field is through the use of mobile computers , including notebook computers , tablet PCs and hand- held computers . A mobile data browser can be loaded on mobile computers, allowing the same capabilities offered by map books , but also the ability to conduct address searches : query attributes of all information , such as schools , types of hazardous material stored at a location , link to digital building pre-plan drawings, and optimal routing . 53 GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessment
