Studying environmental phenomenon in Rub' Al-Khali (Arabic name of"Empty Quarter"), as one of the largest deserts in the world, requires adopting some advanced spatial technologies in conjunction with the data recorded in the field in order to device better understanding. The paper utilizes the technologies of GIS (geographical information systems) and RS (remote sensing) in order to study large amount of weather data recorded in the field from different sources related to oil and gas industry in Rub' AI-Khali desert. The main objective is to identify the wind directions and its movement in Kidan areas and the areas south and east of Shaybah in Rub' Al-Khali desert. The study used different sources of data mainly recorded by the seismic campaigns' base camps and the drilling rig camps or the civil works camps. Wind Roses were created for all metrological weather stations in the study area. Also, the study tried to analyze the dune types using satellite imageries and identify the relation of its shapes to the wind direction. The final aim of the result of this study is to help in planning best locations to build facilities for new major oil and gas project. 展开更多
