Middle Claiborne Aquifer: Alabama, Arkansas, Illinois, Kentucky, Louisiana, Missouri, Mississippi, Tennessee 2006-2008

Digital hydrogeologic surface of the Middle Claiborne Aquifer in Alabama, Arkansas, Illinois, Kentucky, Louisiana, Missouri, Mississippi, Tennessee. The hydrogeologic unit dataset contains 414 rows and 394 columns representing 1-mile grid spacing. In general, limitations of data interpolation included areas of sparse geophysical log control points, log datums not clearly defined for some logs, unknown exact extent of each hydrogeologic unit in subcrop, interpolation limitations, and values averaged over 1-mile grid spacing.

美国阿拉巴马州、阿肯色州、伊利诺伊州、肯塔基州、路易斯安那州、密苏里州、密西西比州和田纳西州境内中克莱本含水层（Middle Claiborne Aquifer）的数字水文地质面数据集。该水文地质单元数据集包含414行与394列，对应1英里（1-mile）的网格间距。总体而言，该数据集的数据插值过程存在多项局限：涵盖地球物理测井控制点分布稀疏的区域、部分测井的测井基准面未明确界定、亚露头（subcrop）中各水文地质单元的确切范围未知、插值方法本身存在局限，以及基于1英里网格间距进行数值平均所带来的精度限制。
