Scientific applications of GPS at the Smithsonian range from regional scale mapping to site-specific surveys. Scientists can use GPS to locate sites within satellite images to help them understand the regional environment. GPS can also be used in documenting specimens collected in the field. In the past, it was often not possible to accurately record the location of collection sites. Smithsonian scientists now use GPS receivers to quickly and accurately identify specimen locations.
