Product Description
The MODerate-resolution Imaging Spectroradiometer (MODIS) Land Cover Classification products contain multiple classification schemes describing land cover properties. The primary land cover scheme identifies 17 classes of land cover defined by the International Geosphere-Biosphere Programme (IGBP) which include 11 natural vegetation classes, 3 developed land classes, one of which is a mosaic with natural vegetation, permanent snow or ice, barren or sparsely vegetated, and water. The MOD12 classification schemes are multitemporal classes describing land cover properties as observed during the year (12 months of input data). Successive production at quarterly intervals of this "annual" product creates new land cover maps with increasing accuracies as both classification techniques and the training site database mature.

The MODIS/Terra Land Cover Type Yearly L3 Global 1km SIN Grid product, MOD12Q1, identifies five classes of land cover. Land Cover Type 1 is the IGBP global vegetation classification scheme, and additional Science Data Set layers for other classification schemes include the University of Maryland modification of the IGBP scheme (Land Cover Type 2), the MODIS LAI/fPAR (Land Cover Type 3) scheme, the MODIS Net Primary Production (Land Cover Type 4) scheme, and the Plant Functional Types (PFT) (Land Cover Type 5) provided in consideration of the Community Land Model (CLM) used in climate modeling. These classes are distinguished with a supervised decision tree classification method.

The images above represent land cover classification Type 5 in the MOD12Q1 product. The image on the left displays tile h13v09 over the northeastern portion of Brazil where the Amazon River enters the Atlantic Ocean. The right-hand image is a subset centered on Belem (in the northwest corner of the large image), and emphasizes the vegetative mix of deciduous and grassy plants in the area.

NOTE: These products are validated to Stage 1.  Product accuracy has been estimated using a small number of independent measurements obtained from selected locations and time periods and ground-truth/field program effort. Although there may be later improved versions, these data are ready for use in scientific publications.
