Cleaves of the Maryland Geological Survey in conjunction with the Towson University Center for GIS. 2003 Physiographic Map of Maryland physiography vector digital data 2nd Baltimore, Maryland Maryland Geological Survey withheld ESRI ArcCatalog 8.2.0.700 en This product delineates physiographic, or geomorphologic, units on a Statewide scale and portrays them in map form. This version of a physiographic map of Maryland supersedes an incomplete, preliminary version having a limited release in 1995. This data set is a vector digitization of line map information. The hierarchical classification of the earth's physiographic features is as follows, in descending order (and generally decreasing size): Realm, Major Division, Province, Section, Region, District, Area, Zone, Locale, Compartment, and Feature. Subdivisions are based on similarities (within) and differences (among) geologic structure, rock type, geomorphic history, and topographic characteristics. At the 1:100,000 scale of this data set, only Provinces through Areas are depicted on the map. Primarily to develop a State physiographic map. Secondarily to provide a base useful for ecoregion maps, vegetation maps, ground-water pollution potential maps, and others. This map is considered valid only at scales equal to or less than 1:100000. ground condition 2003 Complete As needed -79.4938 -75.0450 39.7426 37.8713 185216.140625 575093.625000 25187.843750 230969.375000 None physiography physiographic province geologic province geomorphology regional geomorphology landscape Maryland None None Acknowledgement of the Maryland Geological Survey would be appreciated in products derived from these data.

Those subdivision boundaries were subsequently transferred by hand to paper maps of 30x60-minute quadrangles at a scale of 1:100,000. After repeated checking and revising as necessary of the 1:100,000-scale paper maps, all linework was transferred manually by visual inspection to base-stable mylars of the 30x60-minute 1:100,000-scale maps. Due to the reduced compilation scale of 1:100,000, some subdivision boundaries were generalized or smoothed. All the detail of the larger scale maps was retained on the smaller scale map. withheld 20030310 James P. Reger Maryland Geological Survey mailing and physical address

Attribute accuracy is tested by manual comparison of the source with hard copy plots; double-checked by check plots. Accuracy estimated to exceed 99%. This was checked by visual comparison with the source. Any inconsistencies were corrected. Specific element that were checked included: (1) lines intersect only where intended; (2) no lines are entered twice; (3) all polygons close at nodes; (4) there are no overshoots or undershoots; and (5) all areas are completely described. Data completeness for unrevised digital files reflects the content of the source graphic. Features may have been eliminated or generalized on the source graphic, due to scale and legibility constraints.
