With the launch of ALOS in 2006, JAXA took the initiative to implement the first global-scale systematic acquisition strategy for satellite sensors at fine (2.5m-20m) spatial resolution. Comprising all three sensors on ALOS (PALSAR, PRISM, AVNIR-2), the plan is designed to serve all ALOS user categories and aims at producing spatially and temporally consistent coverages over the planet on a rep...

The progress at the Copenhagen Conference of the Parties 15 (COP15) to include the reduction of greenhouse gas emissions from deforestation and forest degradation (REDD) in the post-Kyoto UNFCCC agreement manifested the demand for reliable remote sensing data streams to support tropical nation’s establishment of measurement, reporting, and verification (MRV) systems to track forest carbon. ALOS...

This paper describes a novel, simple and efficient approach to estimate forest height over a wide region utilizing spaceborne repeat-pass InSAR correlation magnitude data at L-band. We start from a semi-empirical modification of the RVoG model that characterizes repeat-pass InSAR correlation with large temporal baselines (e.g., 46 days for ALOS) by taking account of the temporal change effect o...

An object-oriented change detection algorithm was proposed and experimented to multi-temporal ALOS remotely sensed images. In contrast with conventional pixel-based algorithms, this approach processed homogenous blocks generated by object-oriented image segmentation for change detection. Similar pixels were merged into homogeneous objects by image segmentation at first, and each object (polygon...

This study is describe to development of glacial lake inventory in the Bhutan Himalayas using the Panchromatic Remote Sensing Instrument for Stereo Mapping (PRISM) and the Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2) onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”) to contribute to the evaluation of potential Glacial Lake Outburst Floods (GLOFs) and the...

This paper reports the validation results of burst misalignment for ScanSAR-ScanSAR interferometry of the Phased Array-type L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard the Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”). After the internal software modification on 8 February 2015, ALOS-2 ScanSAR observation mode archives have been available for use in interferometric analysis, ...
