PALSAR Data Access and Tools
Data collected by NASA’s Phased Array type L-band Synthetic Aperture Radar (PALSAR) are integral for efforts including tree species classification and forest canopy estimation, geologic structure interpretation, land surface and soil moisture analysis, topographical change detection, and oil slick assessment. Explore PALSAR datasets and learn more about relevant data tools.
