DEVELOPMENT OF DROUGHT INDEX USING SATELLITE IMAGES

estimation of leaf area index using irs satellite images

estimation of vegetation cover attributes, such as the leaf area index (lai), is an important step in identifying the amount of water use for some plants. the goal of this study is to investigate the feasibility of using irs liss-iii data to retrieve lai. to get a lai retrieval model based on reflectance and vegetation index, detailed field data were collected in the study area of eastern iran....

Using Satellite Images for Drought Monitoring: a Knowledge Discovery Approach

The main objective of this research was to develop a new concept and approach to extracting knowledge from satellite imageries for near real-time drought monitoring in areas of Ethiopia that are experiencing food insecurity. The near real-time data downloaded from the Atlantic Bird satellite were used to produce the drought spatial distribution. Our results showed that approximately 40% of the ...
