The method of edge-spectra ratio was used to drive MTFs of images formed by remote sensor systems and compareson was made between MOS-1 MESSR. SPOT HRV, LANDSAT TM Sensors and COSMOS KFA1000 photograph. Hanning Window was used before the fourier trausfomation to avoid inaccuracy in spectra computing. As the result, COSMOS KFA1000's analog image has better spacial resolution than those digital images. Among the Sensor systems, SPOT HRU and MOS-1 MESSR, which use CCD line sensor, have better MTF than that of LANDSAT TM which use mirror scanning meehanism. And also accuracy of MTFs by edge scanning method was disscused.
