The relationship between NDVI and NDMI has been analyzed using Pearson correlation analysis and showed strong positive relationship. The drought indices have detected drought conditions and identified spatial extents of drought. A comparison between normal year and drought year demonstrates that the amplitude analysis considered both vegetation and moisture condition is an effective method to identify drought condition. We proposed the amplitude analysis is useful for quick spatial assessment of drought information at a regional scale.}, journal = {International Journal of Geological and Environmental Engineering}, volume = {4}, number = {7}, year = {2010}, pages = {271 - 275}, ee = {https://publications.waset.org/pdf/7720}, url = {https://publications.waset.org/vol/43}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 43, 2010}, }
