It is east of Bone Bay and west of Huon Bay , from which it is separated by the Cockerell Peninsula and Cape Ducorps. It is southeast of Astrolabe Island , in the Bransfield Strait . The Louis Philippe Plateau is to the south and the Laclavère Plateau is to the southeast. The bay

Since 2012, the USGS science focus has been directed at topical "Mission Areas" that have continued to evolve. Further organizational structure includes headquarters functions, geographic regions, science and support programs, science centers, labs, and other facilities. The USGS regional organization aligns with

147-593: A federal survey agency, in part to inventory the vast lands added to the United States by the Louisiana Purchase in 1803 and the Mexican–American War in 1848. The USGS was authorized on March 3 in a last-minute amendment to an unrelated bill that charged the new agency with the "classification of the public lands, and examination of the geological structure, mineral resources, and products of

196-449: A lack of accuracy and detail in comparison to older generation maps based on aerial photo surveys and field checks. As the digital databases were not designed for producing general-purpose maps, data integration can be a problem when retrieved from sources with different resolutions and collection dates. Human-made features once recorded by direct field observation are not in any public domain national database and are frequently omitted from

245-626: A new way to view their entire digitized collection of over 178,000 maps from 1884 to 2006. The site is an interactive map of the United States that allows users to search or move around the map to find the USGS collection of maps for a specific area. Users may then view the maps in great detail and download them if desired. In 2008 the USGS abandoned traditional methods of surveying, revising, and updating topographic maps based on aerial photography and field checks. Today's U.S. Topo quadrangle (1:24,000) maps are mass-produced, using automated and semiautomated processes, with cartographic content supplied from

294-410: A non-metric scale virtually unique to the United States. Each of these maps covers an area bounded by two lines of latitude and two lines of longitude spaced 7.5 minutes apart. Nearly 57,000 individual maps in this series cover the 48 contiguous states , Hawaii , U.S. territories , and areas of Alaska near Anchorage , Fairbanks , and Prudhoe Bay . The area covered by each map varies with

The USGS operates the streamgaging network for

931-442: The 15-minute series, was once used to map the contiguous 48 states at a scale of 1:62,500 for maps covering the continental United States, but was discontinued during the last quarter of the twentieth century. Each map was bounded by two parallels and two meridians spaced 15 minutes apart—the same area covered by four maps in the 7.5-minute series. The 15-minute series, at a scale of 1:63,360 (one inch representing one mile), remains

980-439: The 30 x 60-minute quadrangle series. Each of these quadrangles covers the area contained within 32 maps in the 7.5-minute series. The 1:100,000 scale series is unusual in that it primarily employs the metric system . One centimeter on the map represents one kilometer of distance on the ground. Contour intervals , spot elevations, and horizontal distances are also specified in meters. The final regular quadrangle series produced by

The USGS produces several national series of topographic maps which vary in scale and extent, with some wide gaps in coverage, notably the complete absence of 1:50,000 scale topographic maps or their equivalent.
