These data are U.S. Geological Survey (USGS) Digital Line Graph (DLG) coverages for the area in and around Chesapeake and Ohio Canal National Historical Park, District of Columbia and Maryland. The coverages were created by merging the Artemas, Bellegrove, Big Pool, Buckeystown, Charles Town, Cherry Run, Clear Spring, Cresaptown, Cumberland, Evitts Creek, Falls Church, Great Cacapon, Hancock, Harpers Ferry, Hedgesville, Keedysville, Leesburg, Oldtown, Patterson Creek, Paw Paw, Point of Rocks, Poolesville, Rockville, Seneca, Shepherdstown, Sterling, Vienna, Waterford, Williamsport and Washington West 24K DLG Quads. Digital line graph (DLG) data are digital representations of cartographic information. All DLG data distributed by the USGS are DLG - Level 3 (DLG-3), which means the data contain a full range of attribute codes, have full topological structuring, and have passed certain quality-control checks. This data set was created from data transferred in the Spatial Data Transfer Standard (SDTS) format, except for the Buckeystown, Harpers Ferry and Washington West data. These Quads were obtained in the optional DLG-3 (cdo) format.
