The IGBP‑DIS coordinates the development of global land data sets from AVHRR data, producing the 17‑class DISCover land cover dataset that meets IGBP science requirements. DISCover is a 1‑km resolution product derived from monthly NDVI composites of 1992–1993, created via unsupervised classification followed by post‑classification refinement with ancillary data. Draft Africa, North America and South America products are now available for peer review.
The International Geosphere-Biosphere Programme Data and Information System (IGBP-DIS) is co-ordinating the development of global land data sets from Advanced Very High Resolution Radiometer (AVHRR) data. The first is a 1 km spatial resolution land cover product 'DISCover', based on monthly Normalized Difference Vegetation Index composites from 1992 and 1993. DISCover is a 17 class land cover dataset based on the science requirements of IGBP elements. Mapping uses unsupervised classification with post-classification refinement using ancillary data. Draft Africa, North America and South America products are now available for peer review.
