The objectives are to develop a methodology fo gloabal mapping of vegetation with NOAA Global Vegetation Index and geoinformation and to monitor the globala change of bioshere.
The methodology wich has been developed by the authors is based on multi-temporal analysis in which monthly vegetation activity cycles of NVI (Normalized Vegetation Index) were recognized by pattern of vegetation types together with geoinformation such as DEM (digital elevation model) .
As the result of the study, a global vegetation map with eight vegetation types which were defined by multitemporal pattern was produced using three years average of NOAA GVI for 1985 to 1987.
