In April 1992, the International Biosphere Programme's Data and Inform- ation System (IGBP-DIS) began a 1 km land cover project. This has the goal of collecting, archiving and processing daily data from the Advanced Very High Resolution Radiometer (AVHRR) for all terrestrial surfaces, and deriving land cover data from this for the IGBP Core Projects. The efforts of some 29 AVHRR receiving stations, co-ordinated by the United States' Geological Survey's EROS data centre have collected more than 4.4 terabytes of 1 km resolution AVHRR data. From this, a 1 km global land cover data set is being created based on the scientific requirements of the IGBP Core Projects. In consultation with Core Projects the IGBP-DIS' Land Cover Working Group (LCWG) has identified a legend of 17 classes ranging from natural vegetation to developed land and non-vegetated classes. The LCWG has convened a validation working group which is providing information on the accuracies for each cover type. This paper reviews the issues and methods leading to the creation of the global 1 km land cover product, and reports on the project's current status.
