NYC_Atomic_Polygons

Atomic polygons serve as a set of basic building blocks for generating the polygons of many of the district types represented in the CSCL database. Feature classes such as election district, school district, census block, FDNY administrative company, and community district can be dissolved by combining the appropriate fields in atomic polygons.原子多边形（atomic polygons）作为基础构建单元集合，可用于生成CSCL数据库中多数辖区类型对应的多边形要素。诸如选举选区、学区、人口普查区块、FDNY行政分队以及社区辖区等要素类（feature classes），均可通过合并原子多边形中的对应属性字段完成融合操作。
