Abstract
ALSammalyah Island is considered as one of the most important protected sanctuaries in Abu Dhabi emirate and is located just a few kilometers away from Abu Dhabi Island near Umm Annar area just opposite Shati AL Raha beach and characterized by its rich wild and sea life. The importance of the spatial dimension in examining issues such as local and regional development, land use planning, and environmental monitoring is widely recognized. In work of this kind, it is necessary to interrelate information derived from sources such as census, maps, surveys, aerial photographs and satellite imagery, each of which may utilize a variety of methods of spatial referencing. The establishment of an environmental information system will help manage and preserve the environment of AlSammalyah Island," An integrated GIS database for the Island will be established through a three-phase research project, the current phase main objective is to conduct a change detection analysis using satellite imagery and aerial photos of multi scales and multiple dates. Satellite imagery of different spatial and temporal resolutions as well as aerial photographs of various scales are used in this phase of the research to assess and monitor changes occurring in the island. The output of this change detection analysis will be major component of the GIS database that will be established at the end of phase three of the project.
