A model-based approach for mapping rangeland cover using landsat-TM image data

摘要

@@Introduction Empirical models are important tools for relating field-measured biophysical variables to remote sensing data.Regression analysis has been a popular empirical method of linking these two types of data to estimate variables such as percent vegetation canopy cover,and bare soil.The goal of this study is to find a relationship between Landsat-TM original data from single date image and rangeland biophysical variables using multiple regression modeling.
