The Washington DC Area geologic map database (DCDB) provides geologic map information of areas to the NW, W, and SW of Washington, DC to various professionals and private citizens who have uses for geologic data. Digital, geographically referenced, geologic data is more versatile than traditional hard copy maps, and facilitates the examination of relationships between numerous aspects of the geology and other types of data such as: land-use data, vegetation characteristics, surface water flow and chemistry, and various types of remotely sensed images. The DCDB was created by combining Arc/Info coverages, designing a Microsoft (MS) Access database, and populating this database. Proposed improvements to the DCDB include...

The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...

The coverages were created using the gridded data available fromthis ftp site. Most of the gridded data for the United States is ata spacing of 0.1 degrees latitude and longitude. The higherresolution data available for California, Nevada, and part ofArizona and Utah were used for both the U.S. and Western U.S. maps.The gridded data for this area is at a spacing of 0.05 degreeslatitude and longitude.

This CD presents maps derived from a subset of the National Uranium Resource Evaluation(NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data.Approxiamately 260,000 samples were analyzed in the continental U.S. and consisted ofsolid samples, including stream, lake, pond, spring, and playa sediments, and soils.Data for eleven elements were analyzed and included on this release of the NationalGeochemical Atlas CD: Na, Ti, Fe, Cu, Zn, As, Ce, Hf, Pb, Th, and U.The National Uranium Resource Evaluation (NURE) program of the Department of Energy (DOE) collecteda vast amount of chemical data on sediment, soil, and water samples from the United States in thelate 1970's and early 1980's. This element of the...

This CD-ROM contains a digital version of the Geologic Map of theUnited States, originally published at a scale of 1:2,500,000 (Kingand Beikman, 1974b). It excludes Alaska and Hawaii. In addition tothe graphical formats, the map key is included in ASCII text.A geographic information system (GIS) allows combining andoverlaying of layers for analysis of spatial relations not readilyapparent in the standard paper publication. This disc contains onlygeology. However, digital data on geology, geophysics, andgeochemistry can be combined to create useful derivative products--for example, see Phillips and others (1993).This CD-ROM contains a copy of the text and figures fromProfessional Paper 901 by King and Beikman (1974a)....

Debris flows, debris avalanches, mud flows and lahars arefast-moving landslides that occur in a wide variety of environmentsthroughout the world. They are particularly dangerous to life andproperty because they move quickly, destroy objects in their paths,and can strike with little warning. The purpose of this map is toshow where debris flows have occurred in the conterminous UnitedStates and where these slope movements might be expected in thefuture.
