Developed and maintained by the US Geological Survey (USGS) and funded by the National Science Foundation (NSF), the Atlas of Antarctic Research is intended as "a reference, an information framework, an education tool, and a research aid ... [to] promote greater geographic awareness of the continent and the digital geospatial data that describe it." Atlas parameters include Polar Stereographic Projection, units of meters, and Standard Latitude (71 degrees South), among others; source materials range from scales of 1:30,000,000 to 1:10,000 and come from several sources. The interactive Atlas map allows users to view, simultaneously or singly, several layers of ecological information -- such as Rock Outcrops, Lakes, Contours, or Streams. Note that the Map Browser requires screen resolutions of 800 by 600 pixels, 1,024 by 768 pixels, or higher.
