Fire Emergency Service Zones (ESZ) - Open Data

The ESZ is used to verify location in creating calls for service and to determine the proper responses for unit recommendations. Layer was created from the Fire Station Boundary polygon shapefile provided by Ann Moser. Edits were done to edge match with streets and other jurisdictional boundaries. Additional edits for splitting boundaries along N/S Broadway and Alpha Trucks. Purpose Dataset Classification Level 0 - Open Known Uses For CAD Known Errors Data Contact Update Frequency Occasionally using ArcMap. Last known update: January 2012本应急服务区域（Emergency Service Zone，ESZ）可用于核实服务呼叫的位置，并为单元派遣推荐方案确定恰当的响应策略。该图层由Ann Moser提供的消防站边界多边形形状文件（shapefile）制作而成。后续针对其与街道及其他管辖边界的边缘匹配问题开展了编辑修正，并额外针对百老汇南北段及Alpha Trucks沿线的边界拆分需求完成了编辑调整。本数据集分类等级为0级（公开），已知适用场景为计算机辅助调度（Computer Aided Dispatch，CAD），未明确提及已知错误与数据联系人；更新频率为偶尔使用ArcMap进行更新，最近一次更新时间为2012年1月。
