Gazetteer of the Antarctic
This gazetteer lists antarctic names approved by the United States Board on Geographic Names and by the Secretary of the Interior. The Board is the interagency body created by law to standardize and promulgate geographic names for official purposes. As the official standard for names in Antarctica, the gazetteer assures accuracy and uniformity for...
Alaska interim land cover mapping program
In order to meet the requirements of the Alaska National Interest Lands Conservation Act (ANILCA) for comprehensive resource and management plans from all major land management agencies in Alaska, the USGS has begun a program to classify land cover for the entire State using Landsat digital data. Vegetation and land cover classifications,...
Aerial photographic reproductions
Geological Survey vertical aerial photography is obtained primarily for topographic and geologic mapping. Reproductions from this photography are usually satisfactory for general use. Because reproductions are not stocked, but are custom processed for each order, they cannot be returned for credit or refund.
The USGS Hydrography Webinar Series shares success stories from users, provides information on The National Hydrography Dataset (NHD) and other related products, and provides a forum for users to learn more about Hydrography-related topics.
A 1-meter DEM created from a full-waveform LiDAR point cloud. The full waveform LiDAR enabled highly accurate and detailed surface modeling within the small crevices used by nesting birds, acknowledged by the NPS as vital to their understanding of the unique habitat and ecosystem of the Channel Islands.
The south area of the La Honda oil field, California, was discovered during the late 1950s and produced an estimated 595,000 barrels of oil from about 12 wells, including the well in this photo. Most of the oil was produced from an unusual fossiliferous limestone of Miocene age, informally named the Burns sand, that overlies a thick sequence of Oligocene and Miocene volcanic rocks known as the...
Prominence is a term in topography that refers to the elevation of a summit relative to its surrounding terrain. This is different from its overall elevation, which measures the height of the summit above sea level.
WASHINGTON—The President’s fiscal year (FY) 2017 budget request for the U.S. Geological Survey reflects the USGS's vital role in addressing some of the most pressing challenges of the 21st Century by advancing scientific discovery and innovation.
The USGS National Map program is transitioning all of its GIS data download capabilities to its new TNM Download client during the week of February 15, 2016. The new launch page will help users easily find the variety of resources available to get National Map data, download GIS data, visualize and analyze data on the web, or access developer tools such as APIs and map services.
The U.S. Geological Survey is implementing new measures that will improve public access to USGS-funded science as detailed in its new public access plan.
New US Topo maps for Iowa and Kansas are now available in the USGS Store for free download. The new maps of these Midwestern states feature the inclusion of the U.S. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) road data.
A deadly fungus causing population crashes in wild European salamanders could emerge in the United States and threaten already declining amphibians here, according to a report released today by the U.S. Geological Survey.
ANCHORAGE, Alaska – A new digital geologic map of Alaska is being released today providing land users, managers and scientists geologic information for the evaluation of land use in relation to resource extraction, conservation, natural hazards and recreation.
The USGS US Topo map program has entered its third, three-year cycle of revising and updating the digital US Topo maps. To start this new cycle, the USGS National Geospatial Program is excited to announce the inclusion of U.S. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) roads data for the new US Topo maps.
With the release of new US Topo maps for Illinois and South Dakota, the USGS has completed the second, three-year cycle of revising and updating electronic US Topo quadrangles. This means that since late 2009, the USGS has published nearly every map in the conterminous U.S., twice.
Using crowdsourcing techniques, the USGS project known as The National Map Corps (TNMCorps) encourages volunteer “citizen scientists” to collect manmade structure data such as police stations, schools, hospitals and cemeteries...
