Abstract
This study was examined a new generation method for the ASTER-NDVI image at the non-observational day using the temporal MODIS data. It was focused on pixel sizes of ASTER data and MODIS data, and it was feature of this method that effects of land cover classifications were quantitatively analyzed the amount of NDVI changes. Newly "Land covering ratio (termed LCR)" was proposed, and it was indicated that relevance both MODIS-NDVI and ASTER-NDVI was analyzed with LCR quantitatively. This method can improve the spatial resolution of the MODIS-NDVI image by using the statistical technique with LCR. However, when this method was applied to the temporal analysis of ASTER-NDVI, the problem was left in the representative category of the land cover condition.
