South Holland Residential Parcels

This data set contains parcel polygon, tax block polygon, and leasehold polygon features classes, as well as several object classes (tables), for Cook County, Illinois, including a PIN table, a Ref_PIN table, a condo table, and a condo miscellaneous table. The cadastral data for Cook County have previously not been digital nor automated. This project is the initial automation for this information. This database was designed to represent a continuous, non-overlapping spatial database accounting for all land area in Cook County.

本数据集涵盖伊利诺伊州库克县的宗地多边形（parcel polygon）、税籍地块多边形（tax block polygon）与租赁地块多边形（leasehold polygon）要素类，以及多个对象类（数据表），包括PIN表、Ref_PIN表、公寓表与公寓杂项表。此前库克县的地籍数据（cadastral data）既未完成数字化，也未实现自动化处理。本项目为该类信息的首次自动化实现。该数据库旨在构建覆盖库克县全部陆地面积的连续且无重叠的空间数据库。
