Wide swath and high resolution stereo mapping by PRISM-2 onboard ALOS-3

Panchromatic Remote-sensing Instrument for Stereo Mapping 2 (PRISM-2), which will be used for the next high spatial resolution global land observation mission, will extend the capabilities of earlier Advanced Land Observing Satellite (ALOS) missions. PRISM-2 will be able to collect wide-swath (50 km) and high-resolution (0.8 m) images with high geo-location accuracy without ground control points. It will acquire stereo pair images from two telescopes for stereo mapping and precise Digital Surface Models (DSMs). This paper introduces the mission requirement for the next high spatial resolution global land observation mission and a conceptual design for PRISM-2.
