Remote Sensing as a direct adjunct to field, recently playing an important role in the study and assess the natural resource in any part of the world. Anthropogenic changes in land use and land cover and land use are often assumed to be identical, they are rather quite different. Land cover may be defined as the biophysical earth surface, while land use is often shaped by human, socio-economic ...

Forest land managers must determine the effects of their management on nontarget resources, resources for which no current inventory is available, and for which no past trend information exists. The tools available to managers to make these determinations consist of the inventory information gathered for those commodities desired to be produced, i.e., the target resources. A method is proposed ...
