The use of geographic information systems in monitoring and monitoring the green indicator (NDVI) in Alexandria Governorate

This study aimed to use the geominformation technique to detect change in the vegetation cover within the boundaries of Alexandria Governorate, during two different periods (1985-2016) to show the extent of the urban sprawl on agricultural lands. On the other hand, the state tends to reclaim land and desert back. Where this study used satellite images from the Land Sat8 satellite for the years 1985-2016. From the American Geological Survey website from the USGS website. As these visuals were downloaded for free from the USGS website, these visuals were inserted and processed on the ARC GIS program. Where this technology is one of the modern techniques in the study of natural resources (such as cover and vegetation). Thus it was identified the places where there is a vegetation and the places where there is no vegetation, and therefore monitored. Then put it in front of decision-makers in order to plan to exploit it. Or places of urban sprawl on agricultural land. Where geomorphology contributes to the protection of the environment in general, by analyzing space visuals and obtaining information from them according to the item chosen from the video. And put it in front of decision makers, and thus save time, effort and money in field studies. And that is by analyzing the reflected electromagnetic radiation. In our research, remote sensing data were used to confine the green area that changes with time during the periods 1985 and 2016 and to obtain correct information for decision makers in developing investment plans for comprehensive development.
