One of the important objectives of multi-spectral remote sensing instruments is the detection of the optical characteristics of the Earth's surface using high spectral resolution bands. In this study ASTER imagery and reflected radiation in VNIR bands were used to investigate Biological Soil Crusts (BSCs) in the field. By applying IARR (Internal Average Relative Reflectance), FCC (False Color Composite), MNF (Minimum Noise Fraction Transform), MEM (Mathematical Evaluation Method) techniques, BSCs are successfully detected in the Chadormalu desert area of central Iran.This study clearly shows the capability of ASTER data (VNIR bands) to detect BSC or cyanobacteria soil crusts. The MEM method is suggested as an accurate tool for full scale studies.

Here, essential information has been gathered from various sources in the literature to provide a concise description of the imaging modes and benefits of RADARSAT-1/2, data calibration and quality, the data distribution process, the main application domains, etc. The evolution of the RADARSAT-1/2 missions is presented together with future plans. These missions have led to numerous research opportunities and a growing number of applications in the environmental sciences and natural resource management, which are necessary to support both the continuity of RADARSAT data and the improvement of spaceborne SAR technical characteristics.
