Frequently Asked Questions[GLOBCOVER] 01. What are the different GlobCover products? Three different GlobCover products are available:
The MERIS FR Composite products are temporal composites of surface reflectance generated on a bimonthly and yearly basis. They are output of the GlobCover pre-processing chain applying geometric and radiometric corrections. The bimonthly MERIS FR composite is computed every 2 months and provides, for each spectral band, the average surface reflectance calculated from all valid observations of this 2 months period. The yearly MERIS FR composite is computed by averaging the surface reflectance values of the bimonthly product generated over one year. The Land Cover Classification is derived by an automatic and regionally-tuned classification of a time series of the MERIS FR Composites. Its 22 land cover classes are defined with the UN Land Cover Classification System (LCCS). Other Frequently Asked Questions
