EPA environmental
maps of change
 Historical
aerial photographs have helped EPA identify and map very local, site-specific
changes to the environment. The example provided is a hazardous waste site in
Louisiana.
Land-observing satellite data and GIS data have helped EPA understand regional and
community changes to the environment. For instance, the Ohio
Land Change Project mapped changes in land use and land cover during the growth of a
metropolitan region in Ohio.
EPA has
harnessed twenty years of biological data collected by one pioneering state to map water-quality trends in watersheds.
Researchers
are using computerized map data and satellite measurements and developing statistical
techniques that support identifying
changes in wetlands.
