Land Cover Trends Field Photo Map
Field Photo Map
The United
States Geological Survey (USGS) Land Cover Trends field photography
collection is a national-scale, ground-reference dataset which
initially served as a research tool to aid in Landsat-derived
land-use/land-cover (LULC) change analyses and assessments. Between
1999 and 2009, Land Cover Trends scientists collected over 33,000
geographically referenced field photos with associated keywords
capturing existing LULC and regional change process taking place. The
field photography collection represents the most comprehensive
national database of geo-referenced USGS field photography in the
United States. In a project funded by the USGS Climate and Land Use
Change and Core Science Systems Mission Areas, 29,286 photos
distributed across 84 Level III Environmental Protection Agency (EPA)
ecoregions are currently being disseminated to the public.
Integrating Land Cover Trends field photography and online mapping technology provides access to new and archived USGS geographic data needed to conduct science and support policy decisions. Sharing this unique field photography provides an excellent resource for the scientific community with potential to develop future research, such as future repeat photography projects or applications where photos may serve as training or test site data for other remote sensing classifications. Serving USGS data interactively to the public is integral to the USGS mission and provides opportunities for future scientific collaboration by communicating USGS land change research to the broader public and scientific community.
