Mangrove Monitoring with PALSAR Mosaic Products

摘要

Global change research requires high spatial, multi-scale, and consistent remote sensing data. Advanced land observing Satellite (ALOS) implemented a systematic data observation program, providing free polarimetric Phased Array L-band Synthetic Aperture Radar (PALSAR) mosaics to support global change research. The study took Mangrove Nature Reserve of Dongzhai Harbor in Hainan Province as an example, investigating the performance of PALSAR mosaics to map mangrove distribution in this area. In addition, backscattering characteristics of different objects were also compared, which proved the monitoring capability of PALSAR mosaics. The study indicates that PALSAR mosaics is a reliable data source for monitoring mangrove and is helpful to regional-scale research while high spatial resolution is guaranteed.
