High resolution DSM generation from ALOS PRISM - mosaic dataset -

Panchromatic Remote-sensing Instrument for Stereo Mapping, one of onboard sensors carried by Advanced Land Observing Satellite, was designed to generate worldwide topographic data with its high resolution and stereoscopic observation. More than six thousand scenes of digital surface model were processed so far from its images in Japan Aerospace Exploration Agency. The areas of processed scenes cover all Japan land areas and some foreign sites for specific research projects. This paper reports on the latest status of the digital surface model scene archives in all Japan land areas and a mosaicking process which combines them into 1°×1° geographic latitude/longitude tiles. The absolute and relative accuracies of mosaicked digital surface model tiles are validated with ground control points and a variety of height reference data including digital surface models produced by airborne light detection and ranging instruments.
