ALOS Research and Application Project conducts the Earth science research and application research using Synthetic Aperture Radar (SAR) and high-resolution optical sensors onboard the Advanced Land Observing Satellite (ALOS) “Daichi” series satellites.
In the field of the Earth science, for example, estimation of crustal movements associated with earthquakes and volcanic activity as a disaster risk reduction research, monitoring of inundation and sediment disasters caused by heavy rain, forest/non-forest classification and land cover classification, ocean wind and sea ice extent estimation are conducted. This project opens precise global digital surface models and global mosaic images as dataset which can be utilized for various fields.
