Detailed Summary

Japan launched ALOS (Advanced Land Observing Satellite) in January 2006, aboard an H2-A rocket. The 4000-kilogram satellite,
renamed Daichi, was placed in a near-polar orbit. ALOS remote-sensing equipment enables precise land coverage observation and
can collect enough data by itself for mapping on a scale of 25,000:1, without relying on points of reference on the ground.
Some of its objectives are cartography, disaster monitoring, natural resource surveys and technology development.

ALOS Data

The Americas ALOS Data Node archived all ALOS data collected for the Americas, and some data from other parts of the world. The AADN distributed ALOS data until April 1, 2011 to customers physically located within North, South, and Central America with the exception of non-commercial customers located in Brazil and commercial customers located in Canada.

ALOS PALSAR data is available to US researchers from the SAR Data Center.
