| الملخص | The map area is located in the northwesternpart of Iraq, near the Iraqi-Syrianborder.The map areaisgenerally characterizedbylow relief, flat terrain dissected by wadies.This report describes a study that was carried out to perform Land Use-Land CoverMap (LULCM) of Sur Quadrangles Sheet No. NI-37-04, at scale 1:250 000 by implemented two methods: indices and supervised classification using remote sensing data, depending on Landsat 8 OLI satellite image 23/09/2015 and classification procedure; that was developed by USGS and modified by Remote Sensing Division team of GEOSURV-IRAQ.
The LULCM of the map area has produced depending on classification of each pixel of Landsat 8 OLI image to be assigned to one of the six main LULC classes in addition to image indices. Some classes were modified and interpolated after supervised classification using GIS software, because of the interference between these classes in some places on the map area, or as a result of occurrence of scattered pixels for any of these classes with other classes.
Land Useland covermapwasproducedaccording tomaximum Likelihood classifications (ML) of OLI images and Indices using ENVI v. 5.1.These images classified intothreeclasses.The LULC raster image is converted to vector structure, using ARC GIS V.10 program in order toproduce a digital LULC map.
Threetypes of Land Use – Land Cover haverecognized in the map area, these are:Vegetated landclass, Agricultural- Non VegetatedLand. Agricultural- Non Vegetated Land which is further divided into: Cultivated land and Harvested subclass.Barren Land classwhich is further divided into: Dry Salt Flat, Moist Salt Flat, Gypcrete, Sand Dunes and sheet, Mixed Barren Land and Bare Soil. | |
