Name: Karst

Display Field: OBJECTID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The data set was developed by the Virginia Division of Geology and Mineral Resources to depict areas of karst as defined by the presence of sinkholes. Sinkholes were identified from low-altitude stereoscopic aerial photo pairs and traced onto 1:24:000 paper topographic maps, from which they were table-digitized. This is the same data depicted at 1:250,000 scale in Division of Geology Mineral Resources Publications 44, 83, and 167. Field checking has revealed that many more sinkholes are present than are depicted in this dataset. Therefore, these data should serve as a general guide to areas of karst-related sinkhole development, and not as a true indication of the presence or absence of sinkholes at a particular location.
