Over the past two decades, the use of vegetation indices derived from satellite data in the study of natural resources, drought and . . . has great importance. Vegetation indices are calculated using a proper band. Usually the red and near-infrared band, for the different vegetation indices are used. Study the behaviors of vegetation, climate modeling, global vegetation classification, monitoring agriculture crops, desertification and drought studies, environmental protection, energy and water balance of world-class are applications such as vegetation indices. In this study, in order to compare results from different indicators inmonitoring changes in vegetation, NDVI index for the study were extracted, and indexes, DVI, IPVI, RVI and SAVI has been compared. The results show that the closest index to NDVI, are RVI, and SAVI Indicators and both DVI and IPVI index the results are relatively close together, but the differences are many other indicators.
