Use of Space Technology for Sustainable Development in
Iran Iranian Space Agency
Prepared By:Abdolreza Ansari Amoli
In order to employ the guidelines for sustainable development, remote sensing and geographic information system (RS/GIS) have emerged as sub‐systems of space technology.
The application of these techniques in solving of ongoing environmental problems of Iran, as well as, for the future sustainable development of the country is described by reviewing some case studies conducted in Iranian Space Agency (ISA) and direct cooperation with the other companies and universities.

Drought Prediction by Using Artificial Neural Network
The satellite based model established in this research is able to predict and map drought intensity during the next months. Figure (1) shows a schematic diagram of the model. Satellite indices as input data are applied to an artificial neural network model and SPI (drought intensity maps) are produced as output information.
Figure (1)‐ schematic diagram of the model
This research continues to get a robust model in order to predict drought.
Difference between this research and previous works is the type of Inputs and Outputs.In previous works ,Inputs and outputs are Meteorological and Satellite Indices , respectively.But in this research we applied satellite images as input and weexpected to estimate SPI as output.
The final results showed that the best satellite based index for drought prediction by using ANN is TCI.Also MLP is the best artificial neural network model for drought prediction.
