Analysis of the effect of drought on the phenology parameters of vegetation indexes from the time series of MODIS sensor images (case study: Hamadan province)
Drought is one of the consequences of climate change that slowly and over a relatively long period of time affects climate, environment, agriculture, vegetation, water resources and even economic and social sectors. The serious outcome of drought is the reduction of vegetation cover. In this research, using MODIS sensor satellite images of 2001-2020 (20-year period) and CHIRPS monthly rainfall ...

متن کاملNormalization of NDVI from Different Sensor System using MODIS Products as Reference
Medium Resolution NDVI( Normalized Difference Vegetation Index) from different sensor systems such as Landsat, SPOT, ASTER, CBERS and HJ-1A/1B satellites provide detailed spatial information for studies of ecosystems, vegetation biophysics, and land cover. Limitation of sensor designs, cloud contamination, and sensor failure highlighted the need to normalize and integrate NDVI from multiple sen...
متن کاملEvaluation of land degradation trend using satellite imagery and climatic data (Case study: Fars province)
Introduction: Climate change and human activities have a direct impact on land vegetation. Decreased rainfall and increased temperature are among the climate change factors leading to significant changes in water resources and energy balance in affected areas. On the other hand, human activities such as growing population, overgrazing and land use changes that make change in land conditions, al...
