extended abstractintroduction:natural disasters management requires local information in order to be ready against dangers and reduce their procedure. hence, evaluation of landslide occurrence in the area which is prone to landslide due to geographical condition and human constructions is high crucial. ghale chai dam located at ajabshir watershed is one kind of such areas. so the aim of present...

Spatial decision support systems (SDSS) are decision support tools which have been used widely in addressing complicated issues involving a spatial component. The use of SDSS has increased greatly over the last few decades especially in fields such as planning, natural resources management, and environmental science. Traditionally, SDSS have been developed with Geographic Information Systems (G...

At the global scale, high magnitude – low frequency natural disasters are a damaging phenomenon. There is growing recognition that successful disaster response strategies depend upon access to real-time spatial data/information that can be effectively utilized by not only relief agencies but also by local decision makers.
