The U. S. Geological Survey has recently completed a series of new topographic maps of Micronesia in cooperation with the Trust Territory of the Pacific Islands, the Federal agency administering the islands. Monocolor 1:10,000-scale manuscripts were compiled, from which 1:25,000-scale metric quadrangles were derived with symbology consistent with USGS quadrangle mapping. The publication of these new maps coincides with the impending political changes resulting from self-determination referendums held in Micronesia. Local sources have helped considerably with field logistics and resolution of geographic name controversies. Technical aspects of this project included development of tropical feature symbology, location of cadastral subdivisions and associated boundaries and mapping of many outlying coral reefs.
