Thanks to Evan Kane, William Whitlock and David Spears. I was able to create the graphic I needed with the digital data provided by Mr. Whitlock and Spears.

This is perhaps because where you draw the line between them (especially Piedmont and Coastal Plain) is pretty subjective. I had to do something similar myself recently for a region of North Carolina that spanned CP, Piedmont, and Triassic Basin. I took the state's geologic map coverage, in which the only attribute is an abbreviated formation symbol (e.g. Kb, Tec, Czg, etc), summarized the formation symbol field and created a table of physiographic provinces based on the symbol, then joined that table to the geologic map table, then edited the theme's legend to show the three provinces. If you have a geologist handy to interpret the symbols, this can be a pretty quick and easy thing to do. If not, it can be daunting. You get a slightly messy delineation because of the outliers and inliers in each province - mostly little isolated pods of Coastal Plain sediments way up on top of the Piedmont and Piedmont rocks that outcrop in Coastal Plain river valleys. I've attached my "lookup table" so you can get an idea of what I did. Virginia probably has similar map symbols for its statewide geologic map, since a lot of this is standardized, but they are surely not exactly the same, so don't try to use this particular file for your case. Good luck. Let me know if you do find a physiographic province coverage. -- Evan Kane Geologist II NC Dept of Environment and Natural Resources Division of Water Quality - Groundwater Section 1636 Mail Service Center Raleigh, NC 27699-1636 evan.kane@ncmail.net Phone (919)715-6184 Fax (919)715-0588 Paul, Here are ArcView polygons derived from the Virginia physiographic provinces map. The data are in Virginia State Plane North Zone NAD 83 feet. Please note that this map was developed for statewide use at 1:500,000 scale. For specific areas of a particular county, you would need to refer to detailed geologic maps to determine the physiographic province. Detailed geologic maps are not available digitally for the entire state (we don't even have the whole state geologically mapped yet). The .htm file contains metadata pertaining to this dataset. I recommend that you read it. Please let me know if you have any questions or if you need anything else from us. <> <> <> <> ---------------------------------------- David B.
