Neighborhood Watch Areas

This dataset keeps track of the geometry that is used in multiple layers. The resulting layers are HOAs, Neighborhoods, and Neighborhood Watch areas. The polygons in this layer are joined to a database that is maintained by personnel from the Planning/Community Development Department to produce the HOA layer and the Neighborhoods layer, and is also joined to a database that is maintained by personnel from the Police Department to produce the Neighborhood Watch layer. These layers are compiled by a script nightly and are published into the final web maps and other products from those compiled layers, rather than from this source layer. This layer was created around 2009 and was originally only for the Planning department. The Neighborhood Watch aspect was added in around 2014.本数据集用于追踪记录多图层所使用的几何空间数据。其最终生成的图层涵盖业主协会（HOA）图层、社区图层以及邻里守望联防图层。该源图层中的多边形要素会与规划与社区发展部门人员维护的数据库关联，以此生成HOA图层与社区图层；同时也会与警务部门人员维护的数据库进行关联，进而生成邻里守望联防图层。上述三类图层将通过脚本每日夜间完成编译，并基于编译后的成品图层（而非本源图层）发布为最终的网络地图及其他衍生产品。本图层创建于2009年前后，最初仅面向规划部门提供服务；邻里守望联防相关功能则于2014年前后新增。
