ABSTRACT: A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. The key word to this technology is Geography—this means that some portion of the data is spatial. In other words, data that is in some way referenced to locations on the earth. The goal of this study is to evaluate how precisely waterlogging can be identified from medium-goals satellite pictures utilizing EWIS list. The point is to distinguish and mapping of the waterlogged territories in the piece of Farafra Desert Oasis of Egypt. To complete this identification, Landsat-8 symbolism and geographical sheets (1:50,000) have been utilized and handling through Envi 5.3 and Circular segment GIS 10.3, with field perceptions. The waterlogged regions have positive change (+), anyway grounds have negative change (−). Land has been diminished while water bodies have upward pattern. These waterlogged zones have been mapped at a general exactness of 99.22%. The primary explanations behind this descending rate are mostly improvement and anthropogenic mediations. The investigation shows utility of reconciliation of remote detecting and GIS systems for evaluation of waterlogged territories especially in districts where waterlogging conditions happen both because of over the top water system and poor waste. This investigation is recommended that an appraisal of water logging utilizing remotely detected information ought to be completed at customary interims.
