|GPS has made scientific field studies throughout the world more
accurate and has allowed scientists to perform new types of geographic analyses.
Geologists use GPS to measure expansion of volcanoes and movement along fault lines.
Ecologists can use GPS to map differences in a forest canopy. Biologists can track animals
using radio collars that transmit GPS data. Geographers use GPS to define spatial
relationships between features of the Earth's surface.
|GPS at the Smithsonian
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.
