Abstract:
The study depends on using two remote sensing technical and geographical information systems(GIS) drawing in mapping the classification of land cover and agricultural land uses within spatial and temporal changes in the Shatra district during the period (1985 - 2015). The study area is located between longitude (46 - 40 - 46.0) east and two latitudes (31.35 - 31.10) north. Its geographical location is Maysan bordered by the north - east and the Rifai district to the north and Al - Nasr from the north - west while the Nasiriyah district is bordered by the south. While overlooking several areas of the south - west, such as AL.iislah and Sayed Dakhil he area is characterized by its shallow nature, which is invested in agriculture and other uses, which have changed from time to time in most of its land cover types. The study used sensor data (TM, ETM +, OLI) for the American satellite (Landsat - 5, Landsat - 7, Landsat - 8) as well as the use of satellite data (Quikbird2). The Landsat satellite included eight videos for each visual year for two different periods. (1985 - 1993 - 2003 - 2015) in order to know the changes in land cover and uses of agricultural land through the interpretation of these visuals and classification visually and mechanically, GIS software (ARC.GIS.v.10.3 \ 10.2) and ERDAS2014 were used to demonstrate and improve the spectral characteristics of the visuals used in the study to achieve the desired objective. The maps of land cover change produced by the study area, which were digitally classified by the USGS classification, revealed that 6 types of land cover were identified within the first level of this system, Where the areas of the discovered species were calculated for use in the analysis of the change and the output of the classified data in the form of maps showing the change in the spatial distribution of each class in the study area for different periods by adding the colors assigned to each category and the appropriate boundaries and symbols and to build a geographical base for the judiciary. The highest land area was 1,764km2 in 2003, while the wetland category recorded the lowest area of (38.03 km2) for the year 2015. The use of agricultural land for the year 2015 for winter and summer was also based on the data collected from agricultural institutions and departments Therefore, two maps show the distribution of agricultural crops in the study area
