About Land Cover (GLCNMO) data

The Global Land Cover by National Mapping Organizations (GLCNMO) is the data of 1km (30 arc seconds) grid with 20 land cover items. The data were created by using MODIS data observed in 2003 (TERRA Satellite). The classification is based on LCCS developed by FAO. Therefore, it is possible to compare and integrate GLCNMO with other land cover data products based on LCCS.

About Vegetation (Percent Tree Cover) data

The Global Percent Tree Cover represents the density of trees on the ground. The data show the ratio of the area covered with branches and leaves or trees (tree canopy) to the ground surface seen from the above (vertical direction). Satellite images of the whole globe at every 1 square km from the MODIS sensor of Terra were used for the data creation. As for deciduous trees, which drop all their leaves during the period of low temparatre or dryness, the ratio of the most flourishing period of a year (Maximum Percent Tree Cover) was referenced as the Percent Tree Cover.
