The Mapping and Spatial Analysis for the Properties of Al-Kahlaa district soil by Using Geographic Information Systems (GIS)


The aim of the research is to study the properties of the soil of Al-Kahlaa district, which is one of the governorates of Misan province. The nature of the study is analytical cartographyby using GIS. The results of the laboratory analyzes for (15) samples revealed that there was a spatial variation of the physical properties of Al-Kahlaa soil especially in the texture characteristic due to the different conditions of the river sedimentation, as the soils of the riverbanks of Al-Kahlaastream and its branches are a mixture of green clay tissues. It has been proved that GIS programs were able to represent the spatial variations of all these properties in the form of high-resolution maps by using cartographic modeling, specifically IDW
