Abstract :

The aims of the present research were comparison between land use maps produced through IRS-WiFS and MODIS satellite images taken from Semirom and Brojen regions. Various preprocessing, including image rectification was applied with geo-referencing of the image to a registered image with an RMSe 0.5 pixel for MODIS and 0.35 pixel for IRS-WiFS. The atmospheric and topographic corrections were applied using subtraction of dark objects method and the Lambert method accordingly. Image processing including FCC, PCA, vegetation indices and supervised classification were employed to produce the land use maps. Two data sets of both IRS-WiFS and MODIS were used for this study. Finally the produced maps were controlled for their accuracies. Land-use map of MODIS produced with9 category and accuracy of 79.61 and with Kappa of 72.6, and land use map of IRS-WiFS produced with 8 category and accuracy of 90.2 and Kappa of 77.9 .Result showed that land use maps produced with IRS-WiFS data sets have very high accuracy. Results showed the same for land cover map produced with MODIS data sets.
