Address Points Open Data

Address Points contain a single dot for each address or point of interest within the County. This feature is used as the primary despatch source in the County's E911 CAD System. The Street Address subtype includes addresses and "0" address placeholders, which represent parcels and addressed structures. If a structure is present the address point appears within the building footprint, otherwise the point is located at the geographic center of the parcel. Multiple non “0” addresses can be associated with a given parcels, where there are multiple structure and or Real Estate Cards. The Point of Interest subtype is reserved for named places and features that are not tied to a parcel. Some examples of a Point of Interest include: bridges, hazardous curves in a road, entrances to subdivisions, and mile markers. Either subtype can contain civic location, coordinate pairs in multiple projections, common name, and site type information.地址点（Address Points）是为县域内各地址或兴趣点配置的单点要素。该要素为本县增强型911计算机辅助调度（CAD）系统的核心调度数据源。街道地址子类型涵盖各类正式地址，以及代表地块和带地址建筑物的"0"地址占位符。若存在对应建筑物，地址点将设于该建筑的占地面积范围内；若无对应建筑物，则点位设置于地块的地理中心。当存在多栋建筑物或多张不动产登记卡时，单个地块可关联多个非"0"地址。兴趣点（Point of Interest）子类型则预留用于未绑定地块的命名场所与地理要素。兴趣点的示例包括桥梁、道路危险弯道、住宅小区入口以及里程标等。两类子类型均可包含市政地址位置、多投影坐标系下的坐标对、通用名称以及场地类型等信息。
