  • 摘要:Over the years, satellite based remote sensing data have been successfully utilized for mapping, monitoring, planning and development of urban sprawl, urban land use and urban environment. In the present investigation satellite images with GPS and cartographic data are integrated, in order to study the potentiality of creating a cartographic data of an urban area. For this aim the panchromatic image with spatial resolution 1 meter and the corresponding multi-spectral, with spatial resolution 4 meters and 4 spectrum bands, from IKONOS-2, and cartographic data were used. For the rectification of the images there were some ground control points used, measured with GPS. The urban region of study is the Municipality of Thessaloniki, in Central Macedonia, in Northern Greece. After mapping the two images and registering the multi-spectral image to the panchromatic image, fusion between them was attained. The product of fusion was a synthetic image with the advantages of the two initials. The estimation of spectral quality for the synthetic image was attained through statistical criteria. Special urban characteristics (for example: churches, monuments, hospitals, administration buildings, etc) were detected via visual interpretation and the use of a topographic map of the Municipality of Thessaloniki (scale 1:8000), obtained from the urban planning service. Also, there was an effort of modelling the urban environment of Thessaloniki, with the synthetic image, via classification. Special techniques for image classification in urban regions were used. The result was the creation of a thematic picture with a lot of urban characteristics, which can be used as a cartographic background in urban studies
