N2 - Considering there is great similarity between the wave-band design and spatial resolution of the China HJ1A/1B satellite CCD Camera and Landsat TM data, this paper conducts comparison and analysis to the data from the aspects of track parameter, spectral response characteristics and imaging quality. The orbital parameters have little difference. But HJ satellite has two satellites constellations in A/B, and its width is bigger than that of Landsat, which enables it to conduct two-day earth coverage observation, so it is higher than Landsat 5 in time resolution. Radiation precision evaluation results show that in the 4 wavebands of blue, green, red and near-infrared, HJ1A-CCD1 is more sensitive to low radiance, and has a stronger capability to receive low radiance value than TM; in the blue and red wavebands, it also has a stronger capability to receive high radiance value than TM, from which we can conclude that HJ1A-CCD1 has a wider threshold value range than TM in the blue and red wavebands; it has a weaker capability to receive high radiance than TM in the green and near- infrared wavebands; from the perspective of imaging effect, the information amount, texture feature and definition of various wavebands of HJ1A-CCD1 data are not as good as Landsat TM data.
