ALOS is a satellite for land observation with high spatial resolution and wide field of view, providing time series image data sets revealing the land-use and land-cover change. The earth surface is changing due to many dynamics by natural phenomena or events as well as human-induced developments. ALOS is a unique satellite system dedicated to the observation of land-cover dynamics, enabled by the sensor suite composed of PRISM, PALSAR and AVNIR-2 onboard satellite system operated with the interruptible systematic observation strategy, to detect and track disasters. This paper describes the ALOS data applicability with the expected future improvement to fill the gap between the present state of the arts and the ideal performance in the early case studies toward the operational disasters management.
