DMO Mined Out Area Industrial Minerals Underground (MOA)

The DMO Industrial Mineral Mined Out Areas (MOA) dataset identifies the areas of various noncoal industrial minerals in Pennsylvania that have been extracted by various underground mining techniques. The information in this dataset was gathered from digitizing the area of extracted non-coal industrial minerals identified on historic and modern mine maps. The maps to these mines are stored at many various public and private locations throughout the Commonwealth. The maps have been scanned to create a digital archive, and georeferenced to their approximate location for use in a geographic information system (GIS). The dataset is continuously updated as new maps are processed.

DMO工业矿物采空区（DMO Industrial Mineral Mined Out Areas, MOA）数据集可识别宾夕法尼亚州境内采用各类地下开采技术开采的各类非煤工业矿物的采空区域。本数据集的信息源自对历史及现代矿山地图中标注的非煤工业矿物采空区域开展数字化处理所得。上述矿山的地图被馆藏于宾夕法尼亚州境内多处公共与私人机构，工作人员已将这些地图扫描以构建数字档案，并对其进行近似位置的地理配准，使其可应用于地理信息系统（Geographic Information System, GIS）。随着新地图的处理工作推进，该数据集将持续更新完善。
