Final unioned file used for coal resource calculations, southern Wasatch Plateau, Central Utah (wsfing)

This is a shapefile and the final unioned polygon coverage used to calculate coal resources of the lower Blackhawk Formation in the southern Wasatch coal assessment area. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, reliability, overburden categories, and net coal thickness categories. The final unioned coverage was clipped by the resource boundary polygon, which is described in the metadata file for the shapefile WS_BND.

本数据集为用于瓦萨奇（Wasatch）南部煤炭评估区下黑鹰组（lower Blackhawk Formation）煤炭资源量计算的形状文件（shapefile）与最终合并多边形覆盖层。构成该最终合并多边形覆盖层的多边形要素涵盖县级行政区、7.5弧分地形图幅（7.5' quadrangles）、乡镇区、地表与煤炭所有权、可靠性等级、覆盖层类别以及煤层净厚度类别。该最终合并覆盖层已通过资源边界多边形完成裁剪，相关边界的详细说明可参阅形状文件WS_BND的元数据文件。
