Summary of Land Cover (GLCNMO) and Vegetation (PercentTreeCover)

Land Cover (GLCNMO)

• GLCNMO:Global Land Cover by National Mapping Organizations

A GLCNMO is the data of 1km grid with 20 land cover items. The data were created by using MODIS data observed in 2003. A 16 days composite of 2003 is used for land cover classification. The classification is based on LCCS developed by FAO. Therefore, it is possible to compare and integrate GLCNMO and other land cover data products based on LCCS.

PTC (Percent Tree Cover)

PTC represents the density of trees on the ground. The data show the ratio of the area covered with branches and leaves of trees (tree canopy) to the ground surface seen from the above (vertical direction). Satellite images of the whole globe at every 1km2 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 temperature or dryness, the ratio of the most flourishing period of a year (Maximum Percent Tree Cover) was referenced as the Percent Tree Cover.
