U. S. Geological Survey programs in Pennsylvania
The U.S. Geological Survey (USGS) is involved in mapping and studying land, mineral, biological, and water resources and determining the risk from earthquakes and other natural hazards, which are of importance to the citizens of Pennsylvania. This Fact Sheet describes how the USGS is addressing some of the major environmental issues in Pennsylvania, which include availability of mineral resources; contamination of the environment by hazardous wastes; effects of coal mining, oil and gas production, and agriculture on the environment; nutrient input to streams and estuaries; and adequacy of good-quality water supplies. Information on acquiring the thousands of map, book, and aerial photographic products of the USGS also is given.

U.S. Geological Survey programs in Texas
The U.S. Geological Survey (USGS) is the Federal Government's primary source of data on the quantity and quality of the Nation's water resources, its principal civilian map making agency, and its primary provider of information on natural hazards and mineral, energy, and biological resources. The USGS makes unbiased scientific information available equally to all interested parties. Most USGS work in Texas involves the appraisal of the State's water resources in cooperation with more than 80 local, State, and Federal agencies. The foundation of a wide range of hydrologic data-collection and interpretive programs is the stream-gaging program. The Texas network of streamflow-gaging stations, which provides water data for water-resources planning and design, hydrologic research, and operation of water-resources projects, is part of a nationwide aggregation of networks that is unique because of nationally consistent, prescribed standards by which the data are collected and processed. The USGS continues to expand collection of data for paper and digital maps. The best-known products of the USGS in Texas are its 1:24,000-scale topographic maps. These maps depict basic natural and cultural features of the landscape. Maps at this scale (1 inch on the map represents 2,000 feet on the ground) are useful for civil engineering, land-use planning, and natural-resource monitoring, and have long been favorites with the general public for a wide variety of outdoor uses. The USGS also continues to monitor geologic conditions in Texas associated with rare but potentially dangerous earthquakes. Recently, the Nation Biological Service (now the Biological Resources Division) joined the USGS to continue their appraisal of the nation's biological resources.

U. S. Geological Survey programs in Wisconsin
The U.S. Geological Survey (USGS) has served as the Nation’s principal collector, repository, and interpreter of earth science data for more than a century. In this capacity, the USGS in Wisconsin works in partnership with State, county, municipal public works departments, public health agencies, water and sanitation districts, Indian agencies, and other Federal agencies. This Fact Sheet describes some of the current USGS activities in Wisconsin.

US GeoData Digital Line Graphs
Digital line graph (DLG) data are digital representations of cartographic information. DLG?s of map features are digital vectors converted from maps and related sources. The U.S. Geological Survey (USGS) DLG data are classified as large, intermediate, and small scale.
