Urban models can be collected area covering and efficiently based on aerial data like stereo images or LIDAR. While a large number of applications like simulations are already feasible based on the available three-dimensional building representations, a further quality improvement is required for some other tasks. Especially, if very realistic visualisations from pedestrian viewpoints have to b...

Brent D. Ryan first visited Detroit in 1993. Describing this experience, he says: ‘‘The sense of emptiness was overpowering. ... I felt as if I was walking into the ruin of America.’’ In his book ‘‘Design after decline—how America rebuilds shrinking cities,’’ Ryan tries to understand why so many American cities have been losing population, what was and is done to change the fortune of these cit...

BACKGROUND There are many factors influencing postoperative health-related quality of life of adolescent idiopathic scoliosis patients, including the degree of the deformity, culture, differences in geography, rural versus urban living environments, and social factors. The objective of this study was to analyze the significance of geographic factors and their differences influencing the postope...

Urban management in any context has a different economic, social and political structure, which is in harmony with the existing models of organization. In spite of these differences, in order to reach a sustainable urban development, several different conferences should be referred to. In the “Brundtland Commission 1987” about urban sustainable development these definitions have been given: “pr...

We present an image analysis flowchart, based on the use of object-oriented software (eCognition). The maps obtained identify the urban landscape at different scale levels (urban areas and buildings – settlements) and at different organization levels (dense, discontinuous or low-density urban landscape). A particular effort has been made to assess the quality of the results (confusion matrix, K...

regarding iranian old cities, neighborhood has been a real place to live, a space for social interaction as well as economic activities. the concept of neighborhood has always been accompanied with senses of well-being, security and identity. in parallel with urban developments and changing lifestyles, neighborhoods have also faced the significant changes. in tehran as the capital, the changes ...

Within the article a low-cost system for the provision of georeferenced terrestrial images in urban environments is presented. Based on an image with approximate exterior orientation from a low-cost GPS and a digital compass and a 3D CAD model of a visible model as provided from a 3D virtual city model, the exact location of the building in the image is detected automatically and used for a ref...
