United States maps 



Over the last 30 years the U.S. Geological Survey has mapped 

 over 1 ,450.000 square kilometers of the continent previously 

 unmapped. Viewing of geographic features from more than 

 one direction using aerial photographs and satellite images has 

 eliminated earlier problems associated with identification of 

 features from the ground. Persons suggesting names for fea- 

 tures, and those experts charged with the review and recon- 

 ciliation of these proposals, now have available to them the 

 means to define features and characteristics that determine the 

 application of generic terms. Just as mapping must be more 

 detailed to support intensive site-specific investigations, so must 

 the application of geographic names be intensified in some 

 areas to provide locative references for scientists publishing 

 the results of their investigations. A cuiTcnt example of large 

 scale mapping that will require additional names is the series 

 of l;50,000-scale maps of the McMurdo Dry Valleys. In ad- 

 dition to surface mapping, Antarctica's subglacial topography 

 has been revealed by airborne radio echo sounding. The inter- 

 pretation of echo sounding data has disclosed important fea- 

 tures for which names are required. 



The U.S. Geological Survey has focused its mapping on West 

 Antarctica and the Transantarctic Mountains to support the 

 requirements of the United States Antarctic Program. The basic 

 scale of the reconnaissance series of maps is 1:250.000. and 

 nearly 100 maps have been published. Other series include 

 1:500, 000-scale sketch maps, generally prepared in advance 

 of the more detailed 1:250, 000-scale series. These maps are 

 also the basis for charts prepared by the Defense Mapping 

 Agency for ship and aircraft operations and for smaller-scale 

 maps. 



Other maps 



Most nations that operate in Antarctica have published maps 

 in areas of interest. A comprehensive catalog of maps and 

 charts issued by the United States and other member nations 

 of the Scientific Committee on Antarctic Research has been 

 published, as follows:
