Abstract

Fractional Vegetation Cover (FVC) is a very important vegetation structural parameter. The coarse-resolution remote sensing images can be obtained easily and widely used. If the accuracy of FVC derived from coarse-resolution data is promoted, it will bring great convenience for application field. From this point of view, this paper aims to use the high-resolution data to validate the precision of FVC, which is calculated by the coarse-resolution data. We chose the research region in Heihe basin, China as the experiment area. The validation data is generated by fitting the field measured data and Advanced Spaceborne Thermal Emission and Reflection (ASTER) vegetation index - higher resolution remote sensed data. Finally, this paper compares the results and takes analysis.
