A map projection is used to portray all or part of the round Earth on a flat surface. This cannot be done without some distortion. Every projection has its own set of advantages and disadvantages. There is no "best" projection. The mapmaker must select the one best suited to the needs, reducing distortion of the most important features. Mapmakers...
Cartography at the U.S. Geological Survey: the National Mapping Division's cartographic programs, products, design, and technology
The U.S. Geological Survey (USGS) is the prime source of many kinds of topographic and special-purpose maps of the United States and its outlying areas. It is also a prime source of digital map data. One main goal of the USGS is to provide large-scale topographic map coverage of the entire United States. Most of the Nation is already covered. We...Ogrosky, Charles E.; Gwynn, William; Jannace, Richard
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.
