Satellite aerial imagery could play an important role in studying the changes of the shoreline. Aerial photography and remote sensed images can provide an overview of much wider areas and a shorter space of time than the possible used methods of field surveying or GPS. The current study was carried out to investigate the shoreline change due to erosion and/or sedimentation by analysing aerial images and comparing its results with that obtained from the ordinary methods of surveying. A sufficient accuracy investigated for the shoreline change of Port Said city, which located on the northern coast of Egypt, could be obtained by using the advanced soft-wares which covered the biases and noises from aerial images. This study showed that the use of aerial images is a useful tool to pull all information together to understand what happening in the shoreline and predict the future events. 1. INTRODUCTION Many of the Egyptian coastlines are subjected to varying degrees of erosion, high profile example is the region of Port Said city, which is located on the northern coast of Egypt. In order to understand what is happening around the Egyptian coastlines, maritime councils and operating authorities require up-to-date and accurate information about the coastal geomorphology. They are using ordinary surveying, which are concerning with collecting, presenting and using spatial and geographic data in digital form. The principles of land surveying, geomatics utilities contemporary science and technology such as GPS, satellite remote sensing and computer- based geographic information system (GIS) are very useful to help us understanding the changes occurred in the shoreline. For wider area, aerial imagery can be used for a large scale of area in which the measurements, and the results achieved digitally. Coastal engineering studies by remote sensing have not widely established. This is because of the fact that the scientists do not use the full operational capabilities of remote sensing to coastal and environmental studies. Here, the addressed question is that whether aerial imagery can help us to investigate the shoreline change with high accuracy?. Aerial photography can provide an overview of much wider areas in a shorter space of time than the possible used methods of field surveying and/or GPS, but the results accuracy with using aerial imagery must be studied carefully. This study shows a sufficient accuracy to trace the shoreline change of the studied area using the advanced soft-wares which covered the biases and noises from high resolutions images, so the results from images can be improved. 209 Imagery with the highest available spatial resolution is required to detect changes within shorelines. Four primary sources of high-resolution satellite imagery had been evaluated: SPOT (SPOT Image, Corp.), IRS (Space Imagining, Inc.), SPIN2 (Aerial Images, Inc), and IKNOS (Space Imagining, Inc). The 10 meters spatial resolution of SPOT, Smeters spatial resolution of IRS, 2 meters spatial resolution of SPIN2 and | meter spatial resolution of IKNOS. Finally, this study will show that aerial imagery is a useful tool to pull all of information getting from aerial images together to understand what happening in the shoreline and predict future events. 2. STUDY AREA The studied area is the shoreline of Port Said city located on the Mediterranean on the north-eastern coast of Egypt between 31? 17" N to 31° 18’ N and 32° 10’ E to 32? 20' E. This shoreline extends about 15 kilometres to the west of Suez Canal. It has declined seriously over the past 20 years due to the effect of the tidal inlets of El-Manzala lake located at EI-Gamil zone and the existence of the western Suez Canal breakwater. The prevailing wind and wave directions in this area are northwest yearly with net longshore sediment transport moving from west to east. 3. IMAGES DATA The images were taken along the shoreline of Port Said, to the north of Egypt. The shoreline of the studied area extends 20 kilometres long with an elevation ranging from 0.5 meter to 1.5 meter. Four images, during the period 1991, 1995, 1998, and 2001 with 2 m resolution, were available and had been used. Figure 1 shows the different four images. The scale of images was 1:60000.
