Japan: PASCO, a Japanese provider of satellite-based geospatial information, has signed an agreement to distribute data and images acquired by the ALOS-2 Earth observation (EO) satellite which is owned by the Japan Aerospace Exploration Agency (JAXA). As part of this agreement, PASCO will start selling a new InSAR Package service to support different users’ needs for analysis and monitoring over time.
In recent years, natural disasters have occurred more frequently around the world, and research projects aimed at disaster prevention have been actively implemented. In particular, research using Earth observation satellites is gaining attention as an effective method because a wide range of information can be obtained on a regular basis. Among them, the Synthetic Aperture Radar (SAR) satellite represented by Japan’s Advanced Land Observing Satellite 2: Daichi-2 (ALOS-2) is effective for periodic observation because images are suitable day and night, regardless of atmospheric weather conditions. Interferometric SAR (InSAR) analysis is suitable for monitoring land subsidence and deformation associated with a natural disaster, and the need for this is increasing year by year.
In order to respond to such needs, PASCO will provide a new InSAR service on a package-fee basis, so that users who conduct InSAR analysis multiple times in a certain period and/or over long-term monitoring periods can purchase the datasets as a ‘package purchase’.
