{:.extra-spacing} The datasets integrate multiple global remote sensing-derived land-cover products and provide consensus information on the prevalence of 12 land-cover classes at 1-km resolution. For additional information about the integration approach and the evaluations of the datasets, please see the associated journal article:
{:.extra-spacing}
Two versions of the consensus land-cover datasets are available. The full version is the dataset integrating GlobCover (2005-06; v2.2), the MODIS land-cover product (MCD12Q1; v051), GLC2000 (global product; v1.1), and DISCover (GLCC; v2). The reduced version is the dataset integrating the first three products only (i.e., without DISCover).
Each dataset contains 12 data layers, each of which provides consensus information on the prevalence of one land-cover class. All data layers contain unsigned 8-bit values and the valid values range from 0-100, representing the consensus prevalence in percentage. All data layers have a spatial extent from 90ºN - 56ºS and from 180ºW - 180ºE, and have a spatial resolution of 30 arc-second per pixel (~1 km per pixel at the equator).

The datasets can be downloaded in the GeoTiff format for individual land-cover classes (20~100MB each).

Although DISCover is based on older remote sensing imagery (1992-1993), it contains some complementary information which is useful for capturing sub-pixel land cover heterogeneity (please see the associated article for details). Therefore, it is recommended to use the full version of the consensus land cover dataset for most applications. However, the reduced version may provide an alternative for applications in regions with large land cover change in the past two decades.
