First, a Map of the Entire U.S.—and Then the World

The USGS Earth Resources Observation and Science (EROS) Center, celebrating its 50th anniversary this year, was developed at the beginning of the Landsat Earth observation satellite program as a place to store and distribute the imagery. Through the years, EROS has become much more—including a place to advance land cover mapping and monitoring through an unbiased scientific lens...

In the 1980s, as EROS began its International Program, a different type of satellite data factored in. TheAdvanced Very High Resolution Radiometer (AVHRR) sensor aboard National Oceanic and Atmospheric Administration (NOAA) meteorological satellites could cover the entire Earth in one day at a coarse scale and reveal information about vegetation cover and conditions.

Examples of applications of the global database included the World Resource Institute Global Watersheds Vulnerability Assessment, the United Nations Food and Agriculture Organization Global Forest Resources Assessment and the National Geographic Society Satellite Atlas of the World.
