An atlas is a collection of maps; it is typically a bundle of maps of Earth or of a continent or region of Earth.
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps.
The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features throughout the United States and its territories; the associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
The DuPage River is a 28.3-mile-long (45.5 km) tributary of the Des Plaines River in the U.S. state of Illinois.
The National Map is a collaborative effort of the United States Geological Survey (USGS) and other federal, state, and local agencies to improve and deliver topographic information for the United States. The purpose of the effort is to provide "...a seamless, continuously maintained set of public domain geographic base information that will serve as a foundation for integrating, sharing, and using other data easily and consistently".
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface . The term elevation is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.
The North Canadian River is a river, 440 miles (710 km) long, in Oklahoma in the United States. It is a tributary of the Canadian River, draining an area of 17,955 square miles (46,500 km2) in a watershed that includes parts of northeastern New Mexico and the Texas Panhandle.
Geoscience Australia is a statutory agency of the Government of Australia that carries out geoscientific research. The agency is the government's technical adviser on aspects of geoscience, and serves as the repository of geographic and geological data collated by the Commonwealth.
Henry Gannett was an American geographer who is described as the "father of mapmaking in America." He was the chief geographer for the United States Geological Survey essentially from its founding until 1902.
A geoportal is a type of web portal used to find and access geographic information and associated geographic services via the Internet. Geoportals are important for effective use of geographic information systems (GIS) and a key element of a spatial data infrastructure (SDI).
A national mapping agency (NMA) is an organisation, usually publicly owned, that produces topographic maps and geographic information of a country. Some national mapping agencies also deal with cadastral matters.
Geologic mapping of Georgia is the creation of geologic maps—special-purpose maps made to show geological features—of the State of Georgia in the United States. Rock units or geologic strata are shown by colors or symbols to indicate where they are exposed at the surface. Structural features such as faults and shear zones are also shown. Since the first national geological map, in 1809, there have been numerous maps which included the geology of Georgia. The first Georgia-specific geologic map was created in 1825. The most recent state-produced geologic map of Georgia, by the Georgia Department of Natural Resources is 1:500,000 scale, and was created in 1976 by the department's Georgia Geological Survey. It was generated from a base map produced by the United States Geological Survey. The state geologist and Director of the Geological Survey of Georgia was Sam M. Pickering, Jr. Since 1976, several geological maps of Georgia, featuring the state's five distinct geologic regions, have been produced by the federal government.
Carpenter Island (historical) is located on the southern end of the Chester River on Chesapeake Bay in Queen Anne's County, Maryland. It has been known as Carpenter Island or Carpenter's Island since the early 18th century.
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of extraterrestrial planets and moons based on data from U.S. space probes.
Slocums River is a 4.3-mile-long (6.9 km) tidal river in southeastern Massachusetts in the United States. The Paskamanset River and Slocums River really form just a single river, but the freshwater portion kept its earlier Indian name, while the salt-water portion is named for the early settlers of the area, the Slocum family.
The Dry River is an intermittent tributary, 88 miles (142 km) long, of the Crooked River in the U.S. state of Oregon. The stream arises near Hampton Buttes north of Hampton and U.S. Route 20 between Brothers and Riley in the Oregon High Desert. Beginning in eastern Deschutes County near its border with Crook County, it flows generally northwest along the Deschutes–Crook county line, crossing briefly into Crook County before turning slightly south and returning to Deschutes County. Along these upper reaches, it flows roughly parallel to the highway, under which it passes several times before turning sharply north near the Horse Ridge Research Natural Area, 19 miles (31 km) southeast of Bend. Continuing north and re-entering Crook County, it passes under Powell Butte Highway, Oregon Route 126, and Oregon Route 370 before entering the Crooked River 34 miles (55 km) from the larger stream's confluence with the Deschutes River.
West Little Owyhee River is a 63.1-mile-long (101.5 km) tributary of the Owyhee River in the U.S. state of Oregon. The source of the river is at an elevation of 6,508 feet (1,984 m) near McDermitt, while the mouth is at an elevation of 4,373 feet (1,333 m) in the Owyhee Desert. West Little Owyhee River has a 310-square-mile (800 km2) watershed.
Rattlesnake Creek is a tributary, 57 miles (92 km) long, of Crooked Creek in the U.S. state of Oregon. The creek, which is intermittent, begins in the desert north of McDermitt in Malheur County. It joins Crooked Creek southeast of the intersection of U.S. Route 95 and Oregon Route 78 at Burns Junction, about 15 miles (24 km) from the larger stream's confluence with the Owyhee River.
The National Hydrography Dataset (NHD) is a digital database of surface water features used to make maps. It contains features such as lakes, ponds, streams, rivers, canals, dams, and stream gauges for the United States.
