DIGITAL RASTER GRAPHICS (DRGs): 7.5-MINUTE TOPOGRAPHIC MAPS

Status

There is complete statewide DRG coverage for North Carolina; a complete table is listed below. Complete statewide coverage was achieved in September 1997. The DRGs are available on CD-ROMs in TIFF format. Most CD-ROMs contain 64 --7.5-minute quadrangles; some contain only 32 -- 7.5-minute quadrangles because of production quirks. In addition, each CD-ROM contains corresponding 1:100,000 (100K) and 1:250,000 (250K) sheets.

The cost is $7.55 plus state tax (for orders destined to NC addresses) per CD-ROM (total of $8.00). There is a nominal charge for shipping and handling. The price is subject to change. The base price is based on reproduction costs. There are no discounts for multiple CD orders or for government agencies.
