Service Description: For the purposes of obscuring sensitive boundaries the Commonwealth of Virginia was divided into a hexagon grid (individual hexagons are ~250 acres in size). Resources that have been surveyed in the inventory of the Department of Historic Resources (DHR) were ranked by levels of cultural interest, defined in the attribute field MAX_Preservation_Index as:
3 = Listed as National Historic Landmarks (Highest)
2 = Listed on, contributing to, or eligible for listing on the National Register of Historic Places/Virginia Landmarks Register
1 = Sites/properties without formal evaluations of eligibility that are recommended to have potential for eligibility
Resources with rankings attached were joined to the hexagons and all attribute data was stripped away. The index value for each hex is equal to the highest value of cultural significance contain within it. For example if three resources overlap within a hexagon with values of 2, 1, and 3 the value of the hexagon will be 3. The index value is not cumulative.
This dataset does not include sites or properties that remain unevaluated, nor does it include areas of the commonwealth that have not been surveyed for cultural resources.
