The sinkhole locations shown on these maps have been digitized and are available as a draft ESRI shapefile. DGMR plans to complete a quality control analysis and modifications of the digital representation of these locations prior to release to the public.

<p>
The original project to identify sinkhole locations is complete. New data concerning sinkhole locations is, however, published on geologic map products.</p>

neededImprovements
<p>
The present collection includes scanned images of topographic maps showing hand-plotted locations of sinkholes. These maps will serve as the basis for future derivative map products including karst hazard and sinkhole intensity maps.</p>

<p>
There is a substantial interest in understanding the hazard potential associated with sinkholes and karst in many areas of Virginia. As development continues in the Valley and Ridge province, it is expected that the demand for this data will increase.</p>
