دور تقنيات الاستشعار عن بعد في قياس مساحات اهوار جنوبي العراق للمدة 1977-2016

چکیده

Advantage of the space visualizations great quality to distinguish the spatial, which represents smaller phenomenon can be picked up from the sensor, and accurate discrimination spectroscopic are ranges of wavelengths in which the working sensor packages and recorded different values of reflectivity or emissivity spectral precision radiation discrimination, a susceptibility sensor on the accurate recording of the change in energy Radiation over represents different levels. In this paper, an attempt to measure the change in the marshes of southern Iraq, an area for the period 1977-2016 has been the merger and Almozaiak program Erdas 2014, while the rating process orientated has been through Erdas program, while the dependence on ARC GIS software in the conversion process from Raster to Boleikon and the program itself has been used in the output process. It turned out through the study area marshes of southern Iraq have seen a large fluctuation in the water area for reasons of lower earned water imports from the Tigris and Euphrates rivers, as the marshes lost about two thirds of the area during the period 1973-2016, which is reflecting the amount of drying that has plagued marshes during this period time, reaching an area of approximately 2016 (6852 km2), while the total area of approximately 1973 (19 788 km 2).
