PLSS Sections

This data set is a polygon shapefile representing Public Land Survey System (PLSS) sections. The data are a subset of the Wisconsin DNR's 'Landnet' database, automated from 1:24,000-scale sources. *DNR staff have added an alpha field for the range direction field in this layer called DIR_ALPHA which uses W and E instead of numerical direction codes.本数据集为多边形形状文件（shapefile），用于表征公共土地测量系统（Public Land Survey System, PLSS）的地块区段。该数据为威斯康星州自然资源部（Wisconsin DNR）「Landnet」数据库的子集，由1:24000比例尺的数据源自动化生成。*DNR工作人员为本图层新增了用于表示区间方向的字母字段DIR_ALPHA，该字段使用W（西）与E（东）替代了原有的数值方向编码。
