The aim of this study is to demonstrate the case studies on integrated approaches of RS and GIS
techniques for different forest studies. For this purpose, different test sites of Mongolia have
been selected. Within the framework of the study, it was assumed that there is an operational
GIS that stores historical data about the forest and there is need to produce updated forest maps
using multi-temporal optical RS data sets as well as to produce a forest biomass map. For this
purpose, multi-temporal optical and microwave images as well as topographic and forest
taxonomy maps have been used.
