The mission objecttives of ALOS-3 are (1) to contribute safe and secure social including provisions for natural disasters, and (2) to create and update geo-spatial information. The wide-swath and high-resolution optical imager is designed to be achieved the missions, which consists of the panchromatic band with 0.8 m ground sampling distance (GSD) and multi-spectral six bands with 3.2 m GSD, and the observation swath width is 70 km at nadir. In this study, mission overview, and planned- and expected-products of ALOS-3 are introduced.
