Topographic Maps

These are general-use maps at medium scales that present elevation (contour lines), hydrography, geographic place names, and a variety of cultural features. Current-generation topographic maps are created from digital GIS databases, and are branded "US Topo." Historic maps originally published as paper documents in the period 1884-2006 are available as scanned images.

Topographic Maps

Topographic maps are a signature product of the USGS. They were essential for integrating and analyzing place-based information, and were widely used by receationalists. After 125-year legacy of topographic mapping (1884-2009), the USGS embarked on an innovative future of integrating historical maps with computer-generated maps from a national geographical information system (GIS) database.

Kansas Flood Map

This map shows the location of stream gages where the water level is currently at or above flood stage (depicted as a black triangle) or at high flow (depicted as blue circles) The high flow conditions are expressed as percentiles that compare the current (i.e., within the past several hours) instantaneous flow value to historical daily mean flow values

US Topo - the Current Generation of USGS Topographic Maps

US Topo maps are modeled on the familiar 7.5-minute, 1:24,000-scale quadrangle maps of the period 1947-1992, but are mass-produced from national GIS databases on a 3-year cycle.The maps are layered PDF documents with geospatial extensions. They are downloadable free of charge through several interfaces.

Historical Topographic Map Collection (HTMC)

USGS topographic maps originally published on paper in the period 1884-2006 have been scanned and published as PDF documents. This collection is of topographic quadrangle maps with scales between 1:10,000 and 1:250,000. These historic documents are downloadable free of charge through several interfaces.

Energy and Environment in the Rocky Mountain Area

To allow for a comprehensive evaluation among different energy types, an interdisciplinary team of U.S. Geological Survey (USGS) scientists has developed an online Interactive Energy Atlas for Colorado and New Mexico. The Energy and Environment in the Rocky Mountain Area (EERMA) interdisciplinary team includes investigators from several USGS science centers.
