ul 2004 International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 In the second occasion where there was no histogram matching the image that came up is the following (fig.4). Figure 4. Synthetic image 2. Municipality of Thessaloniki. The software ERDAS IMAGINE 8.5 was used for the processing of the images while the GCP'S mensurations were actualized by the Leica 500 receiver (with the AT502 antenna) and their processing was actualized by the LEICA SKI-PRO and ISTOS — 2000 programs. 2.2.2 Evaluation of spectral quality of the synthetic image: In a merging procedure it is extremely important to maintain the primitive spectral information in the final image as well. For this reason the synthetic images were studied for their spectral accuracy, through statistical criteria such as mean values, typical variations and coefficient correlation. Analyzing the two synthetic images led to the following conclusions: With a simple visual observation of the two synthetic images one can easily discover that the synthetic | image has better appearance. The results of the spectral examinations through statistical criteria clearly indicate as better method of merging the one where histogram matching between the layers of the multispectral and the layer of the panchromatic is attained, that is the synthetic | image (Tab. 5). Statistical criteria Synthetic 1 Y Synthetic 2 Table 5. Evaluation of the two merging methods used after examining their spectral accuracy. 3. SYNTHETIC IMAGE - APPLICATIONS The second stage regarded to the applications that took place in the synthetic image like: a) Visual interpretation and b) Classification For the classification of the synthetic image and its estimation, the ERDAS IMAGINE 8.5 software was used. 3.1 Visual interpretation of the synthetic 1 image With the assistance of cartographic data an attempt to improve tracking down urban characteristics (e.g. hospitals, buildings of administration, monuments etc.) via visual interpretation takes place. Here are some examples (Fig.6,7,8) Figure 8. Prefecture of Thessaloniki Figure 7. Hospital Improvement of tracking down urban characteristics can be useful for creating city plans that communicate better with the user. It can also become a basis for a G.LS. application. 3.2. Classification of the synthetic 1 and estimation of the classification 3.2.1 Classification: The type of classification selected for the synthetic 1 image was supervised and was accomplished with the maximum likelihood method. The selection and receipt of the samples was based on the V.LS. model (Vegetation- Impervious surface-Soil),(Ridd 1995, Ming C. H. 2002). Estimation of the classification through close examination of the error matrix and the Kappa statistics followed. The selected classes were: * Grassland, trees - healthy green grass vegetation and tree and/or shrub vegetation. * Buildings - bright impervious surface, like rooftops, metals and tiles. * Streets - medium impervious surface, like concrete and weathered asphalt.
