Abstract
With the objective of developing accurate global image data and to find the effects of difference of observation time, several reliable global cloud free data sets of Terra MODIS and Aqua MODIS will be developed utilizing personal computers. Out of 36 bands seven bands (Band 1 through 7) with similar spectral features to those of Landsat-7 ETM+ are selected, since these bands cover the most important spectra to derive land cover features. And then, some statistical information of the developed data sets and NDVI computed from the data sets were investigated. From the analysis, it was clarified that the means and standard deviations of band 2, 3, 4 and 6 of Aqua MODIS data are more slightly larger than those of Terra MODIS data although the values of band 5 and 7 of Aqua MODIS are more slightly smaller than those of Terra MODIS data. And it was also found that NDVI of Aqua MODIS data computed from band 2 (NIR) and band 1 (R) are also higher (approximately from 0.03 to 0.05 at the range of NDVI) than those of Terra NDVI because of the above mentioned reasons.
