Analysis Ready Data of the Chinese GaoFen Satellite Data

Analysis Ready Data (ARD) has been greatly recommended by the Committee on Earth Observation Satellites (CEOS) for simplifying and fostering long time series analysis at large scale with minimum additional user effort. Landsat ARD successfully made widely used analysis. Subsequently, Chinese satellite data similar to have processed will be into ARDs promote use of data. At first stage mission, 4 Wide Field Viewing (WFV) GaoFen 1 (GF1) covering whole China surrounding areas ARD. The is provided as standard tiles under a common unified projection per pixel quality assurance metadata tracing back further processing data, which are finally stored Hierarchical File (HDF); furthermore, all spectral bands georegistered radiometrically cross-calibrated top atmosphere (TOA) reflectance atmospherically corrected surface (SR). Therefore, can easily produce land cover change maps retrieve geophysical biophysical parameters.
