Abstract: | This study is part of the water quality research carried out in the Mahakam Cluster of the East Kalimantan Project. Look up tables were constructed from a water optical model.. These were used for the mapping of water quality parameters from LANDSAT 7 ETM and MODIS daily reflectance (MOD09GA/MYD09GA) images. For validation, the TSM maps derived from MODIS were compared to field data and in addition the TSM maps derived from LANDSAT 7 ETM and MODIS TERRA were compared with each other. In situ TSM concentration field measurements and TSM concentrations derived from MODIS daily reflectance image show a good correlation. This appears from the type II regression analysis result, R2 =0.87, RMSE = 0.147 and R2 =0.97, RMSE=0.0895 both for AQUA and TERRA, respectively. From this result it can be concluded that look up tables can be used to derive TSM concentration from remote sensing imagery. Comparing a TSM MAP derived from LANDSAT ETM and one from MODIS TERRA, the result is a low correlation with R2 = 0.21 and RMSE = 0.468. The TSM map concentration derived from LANDSAT 7 ETM is underestimated compared to the TSM concentration from MODIS TERRA. Further studies need to be carried out to investigate this discrepancy. Keywords: TSM, Mahakam Delta, LANDSAT 7 ETM, MODIS AQUA (MYD09GA), MODIS TERRA (MOD09GA), Look up Table |
