Abstract:
The changes in land cover and land uses require monitoring and detection of these changes and their signature on detection maps. The use of remote sensing techniques is the best way to detect this change and to know the direction of change and to predict the changes that may occur .The study aim is to observe the terrestrial cover changes and land uses for the period 1977 - 2016 of the study area that located between latitude circles (30◦ 44 and 30◦ 59) north, longitude arcs (46◦ 13 and 46◦ 49) east UTM; WGS 84, the study area located in the eastern side of Thi - Qar province, the administrative border of Al - Dawaiyah area / Al - Shatara city and the administrative border of Al - Islah area / Al - Nasiriyah town, by use Landsat satellites and explain it by use the visual explanation, and represented it in schedules according to the suitable ecological classification of the study area, and represented it in high proficiency maps to establish geographic information base and put on maps called the change discovery maps, and compare it with to reach to the best system supervised and unsupervised to discover the change and establish geographic information base by uses GIS to save the support information that can be renewed and followed, by uses three systems ,first by Erdasimagine2014 change detection tool, and arc Gis 10.2 by overlay tools like union eras & intersect .finely subtract swath affix from precedent to know true results. In addition, studying the natural characteristics of structure, surface and the water sources through branches of the only feeder to the marshes of the study area which is Al - Gharraf river. Marshes of the study area are affected directly and carried its qualities. Also, studying the climate with its elements, soil, the natural plant showed in objectivity maps and old human energetic represented by agriculture activity, rural settlement and villages, ruins sites supported by maps of its locations and measurements which is classified according to the ecological classification that is proceeded in the study.
