3.5 Multispectral classifications A hybrid method has been used for multispectral classification. First, an unsupervised classification of the color composite SPOT HRV and IKONOS images has been realized (with ISODATA algorithm), where the selected 10 classes are defined. Several confusions occurred in some areas of the image: for example built areas and uncovered soil areas. In order to improve classes definition a vegetation map at 1:2,000 scale, realized in 1993 has been used. After classes regrouping followed a hybrid supervised classification for 6 classes: streets and paths, parceled areas with buildings, lake surface, trees vegetation, grass vegetation and uncovered soil. The accuracy classification was estimated using the standard, single-data, qualitative accuracy assessment procedures for each image. Producer and user accuracy were calculated for each change class, along with the overall accuracy (error matrix and Kappa Index of Agreement analysis) (Congalton and Green, 1996). Global accuracy for the obtained classifications ranged between 90.44% and 96.53%. Kappa coefficients ranged between 0.86 and 0.93. 4 CONCLUSIONS Digital processing techniques in the Bucharest study area, during 1964-2007, highlight the following: e The available medium and high resolution satellite images allow a cinematic multisensor approach. The high resolution Corona image scanned with care, provides high levels of detail on ground features. In this case three- dimensional information can be extracted from the CORONA imagery using only a small number of GCPs. Corona and IKONOS images are important means for changes detection in urban and peri-urban areas. Also SPOT-HRV medium scale images ensure a satisfactory level of accuracy for monitoring changes detection in urban areas; e In order to complete information for these images, historical aerial photographs at 1:5,000 scale, acquired in 1994 (from the same date) have be used for correction of satellite images. Applied techniques (preliminary radiometric and geometric processing, data compression, contrast and edge enhancement, multispectral classification, post-classification processing) assured also the maximum accuracy in data processing (without altering the initial information) and in the results of interpretation; » Changes between the imagery were determined partially through visual interpretation, by elements such as location, size, shape, shadow, tone, texture and pattern (Corona image), partially by six classes hybrid supervised classification (SPOT HRV and IKONOS): streets and paths, parceled areas with buildings, lake surface, trees vegetation, grass vegetation and uncovered soil. Subsets of the images were generated within and near the city where changes were evident. Noticeable changes in land cover between the imagery were manually or automatically digitized and imported into a GIS, where changes could be visualized and analyzed. Other changes are presented in the form of thematic maps highlighting changes of urban development and ecological comfort parameters. The first 25 years of the study period (1964-1989) are characterized by growth of industrial areas, high density apartment buildings residential areas and leisure green areas by demolition of houses or cultural heritage areas (22 hundred years old churches and other architectural monuments) - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XXXIX-B7, 2012 XXII ISPRS Congress, 25 August — 01 September 2012, Melbourne, Australia see SPOT HRV and IKONOS images. The second period of 18 years (1989-2007) highlighted considerable growth of residential areas in the city neighborhood, simultaneously with diminish of green areas and massive deforestation in confiscated areas before 1989 by communist regime and returned to the original owners. The study demonstrates once again that remote sensing and photogrammetry deliver means of gathering useful information regarding present status and future urban trends. Continuous analysis of repetitively acquired data, in the same area allows urban and extra urban areas change detections, easing the process of finding proper solutions and revision of local politics in urban development in accordance with UE regulations. 5.
