The EO-1 project is assisting the Landsat 7 program with global island acquisitions by supplementing coverage with data from the Advanced Land Imager (ALI) sensor.

The island acquisition map for the EO-1 ALI sensor reveals the spatial location of scenes within the U.S. Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) archive. Each red dot on the map indicates the location of an island scene with its associated place name, but does not represent the exact footprint of the area imaged. Likewise, the red dots do not reflect temporal repetition of a scene at a given location. The static map graphic is updated periodically to show a representation of acquired scene coverage within the archive. EO-1 coverage does not encompass the entire globe because data collection events are based upon customers Data Acquisition Requests (DARs).
