Information technology has developed rapidly. In recent years, the application of Remote Sensing and Geographical Information Systems (GIS) has become an essential demand in all fields, in which including the study of Environment and Natural Hazard. The northern coast of Egypt has changed clearly in many areas along the Mediterranean Sea for many different reasons such as influence of human activities and by the action of waves and current.
The position of the Egyptian Northern Coast is very important in socio-economy system of Egypt, and is the place where there is also a lot of urgent problem such as shore corrosion and conserving the environment. Economic activities didn't obtain high result by limited knowledge about characteristic of geological environment, which have negative effect on geological and ecological environment. Remote Sensing and Geographical Information System (RS & GIS) has applied in many fields throughout, in there including the study of geological environment. This application has made great advances in management for coastal environment and developed activities in order to achieve high economic effect. Therefore, application RS & GIS in researching geological environment and natural hazard at Northern Coast of Egypt is right and necessary.
