Abstract: The Advanced Land Observing Satellite (ALOS) was successfully launched by the Japan Exploration
Agency in January 24th of 2006, with the mission of obtaining high quality optical and microwave images of the planet, for mapping and natural disaster monitoring. Its payload comprises the Phased Array L-band SAR
(PALSAR), and two optical sensors: AVNIR-2 (Advanced Visible and Near Infrared Radiometer type 2) PRISM
(Panchromatic Remote-sensing Instrument for Stereo Mapping). A rigid control of orbit and attitude allows a very precise pointing capability, which is expected to accomplish the specifications up to 1:25.000 scale mapping, without ground control points. All these characteristics made ALOS very convenient to map the
Amazon, considering the difficulties of access and the general geographic condition of the region.
