| Abstract | ||
| In this research, the ground temperature was calculated within a part of the province of Sulaymaniyah - northern Iraq, using the thermal bands(low acquisition, and high acquisition thermal bands) of the ETM+ sensor mounted in the LANDSAT 7 satellite. Practically, a linear profile within Dukan Lake (province of Sulaymaniyah) , has been indicated, and the temperature degree for its pixel has been calculated from both low acquisition and high acquisition thermal bands, this process has been implemented utilizing ERDAS Imagine 9.2 software package; the obtained results indicate that there is a significant convergence between the values of temperature calculated from both thermal bands indicating the accuracy of the adopted Mathematical Model in the calculation . In the second part of the work, the distribution of temperature degree over the study region has been extracted as a raster map. By averaging both low gain and high gain thermal bands. | ||
