Abstract

To perform a good interpretation and spatial analysis for remote sensing data like satellites images, it is better to enhanced these images by using Image Processing techniques. In the same time to make good interpretation for any study area it is better to collect more than one data about this study area. In this research the study area located in Qaraqosh District in Southern East of Mosul city north Iraq. Two remote sensing data are collected about this area; spectral bands of Enhanced Thematic Mapper Plus sensor (ETM+) Landsat 7 satellite, and panchromatic band of SPOT satellite. The spectral  bands  of Landsat 7 satellite with   high  spectral  resolution     (8 bands) with spatial resolution 28.5 meter. While panchromatic band of SPOT satellite consider as high spatial resolution (10 meter). The merging technique which applied in this search are called Brovey transformation. The side effect of this merging caused blurring in merged image. To enhance this blurring, convolution filter has been performed. Finally the enhanced merged image (with high spectral and spatial resolution image) is ready to interpretation and classification.
