Continuous oil palm distribution maps are essential for effective agricultural planning and management. Due to the significant cloud cover issue in tropical regions, identification of from other crops using only optical satellites is difficult. Based on Google Earth Engine (GEE), this study aims evaluate best combination open-source microwave satellite data mapping by utilizing C-band Sentinel-...

The Santa Catarina Southern Plateau is located in Brazil and a region that has gained considerable attention due to the rapid conversion of typical landscape natural grasslands wetlands into agriculture, reforestation, pasture, more recently, wind farms. This study’s main goal was characterize polarimetric attributes experimental quad-polarization acquisition mode Advanced Land Observing Satell...

Processing of ScanSAR data for interferometric applications requires careful attention to the phase and position accuracy to obtain interferometric products with high correlation and continuous phase across the bursts. We describe an interferometric processing system developed for ScanSAR data acquired by the ALOS PALSAR instrument able to produce differential interferometric products with 350 ...

The author introduces the status of the Japan Aerospace Exploration Agency’s synthetic aperture radar (SAR) programmes and their scientific returns from the last 20 years of activity. The Earth observation programme was started using active microwave sensors in the early 1990s. Spaceborne SAR aboard Japanese Earth Resource’s Satellite-1 (JERS-1) was the pathfinder, and airborne polarimetric and...

Current operation mode of SAR can be roughly divided into two types: strip-map mode and burst mode. The most conventional mode is strip-map mode, in which the swath width is quite limited. The other type is burst mode, which is an active option to overcome this limitation by cyclically scanning several subswaths, known as ScanSAR. In addition, Envisat ASAR has another type of burst mode, that i...

This study estimates CO2 sequestration by forests in Japan using Land Remote Sensing Satellite (Landsat) Operational Land Imager (OLI) and the Advanced Land Observing Satellite (ALOS) Phased Array L-band Synthetic Aperture Radar (PALSAR) remote sensing data for the in-depth retrieval of forest growth stages (tree age). Landsat imagery was used to develop a detailed forest cover map, while the P...

The mangroves of the Rufiji Delta are an important habitat and resource. The mangrove forest reserve is home to an indigenous population and has been under pressure from an influx of migrants from the landward side of the delta. Timely and effective forest management is needed to preserve the delta and mangrove forest. Here, we investigate the potential of polarimetric target decomposition for ...
