Manager’s Corner Current, accurate transportation data is essential to support time-based travel. Geocoding incidents also supports risk analysis. ogy, and transportation, district staff model new construction, flooding, critical slopes, winter operations, and travel slowdown on steep roadways. By combining different types of framework data, district personnel can model, understand, and solve many complex problems. And Finally—Geodetic Control Public safety mappers perform spatial mapping and analysis in a carefully defined and controlled coordinate-based world, though they tend not to focus on positional and spatial accuracy and instead are more concerned with getting trained personnel and sufficient and appropriate emergency equipment to incidents as efficiently and safely as possible. Behind the scenes, mapping data is carefully connected to a precise system of points and arcs that includes benchmarks, survey control points, and regional traverses. Local agencies rely on federal, state, and county agencies to establish and maintain the control net. For most agencies, the county surveyor is the resident expert. Accurate and extensive survey control supports all that emergency response personnel do. Survey control is important and becomes more so as regional response models and communication protocols are developed. For now, public safety mappers should get acquainted with their county surveyor and engineer! Special Data—Shape of Things to Come This article briefly summarized seven types of framework data that are used every day by public safety mappers. There is an extensive set of www.esri.com essential information that does not fit directly into framework categories. Here is a short list of special data used for risk/hazard/protection/ value mapping: Fixed and Portable Facilities (Protection) Apparatus Personnel Special Services Other Essential and Critical Facilities (Protection, Value) Historic Incident Data (Risk) Water Supply (Protection) Land Use/Zoning (Hazard, Value) Growth Management (Hazard, Value) Special Hazards and Occupancies (Hazard, Value) Industrial Natural, Environmental Cultural Census Demographics (Value) Communications, Command and Control (Protection) Acknowledgments The author thanks the staff and administration of Kent Fire/Fire District 37 and their contributing agencies. Special thanks to Kent City Public Works, Valley Com, and the Zone 3 mapping group. Through partnering and mutual commitment, great things are possible. ArcUser Summer 2010 39
