3D models of urban sites with good geometry and facade textures are needed for many planning and visualization applications. Approximate wireframe can be derived from aerial images but detailed textures must be obtained from ground level images. Integrating such views with the 3D models is difficult as only small parts of buildings may be visible in a single view. We describe a method that uses...

The growth of urban populations in recent decades requires physical elements such as residential, commercial and cultural spaces and the development of infrastructure such as streets and highways, which will open a new horizon to the historic texture of cities and how to preserve and restore them. The development of new urban textures along with the lack of attention to the historic texture and...

Cities, as the focused centers for human residence and settlement, are faced with various issues and problems. The high rate of crime and anomic behavior are characteristics of today’s major cities. Fear of crime and anomic behavior is perceived as the most important reasons leading to a decline in the use of public spaces in cities by its residents. According to the mutual relation between env...

The rapid expansion of urban construction land has become the major characteristic of urban land-use change in China today. Meanwhile, the rapid urbanization process has led to the great changes of urban landscape in China, and it also has had certain impacts on environmental factors such as climate, soil, hydrology, biodiversity, etc., then it has made the overall ecological environment deteri...

Change extraction of building is needed to revise building data effectively. Many change detection algorithms use height difference analysis using temporal data such as LIDAR. However, remarkable changes of buildings cannot be detected in urban dense areas. On the other hand, building textures might change with higher possibility. However, the change cannot be detected due to influences of shad...

The focus of the research is mega-block in New Belgrade built in 1960`s, before and after transformation. The aim of research was to compare the parameters of bioclimatic urban design before and after the intervention. The results show decrease due to shading and evapotranspiration of 1°C to 2°C, in the central part of communal open space and increase of temperature along the edges of the block...

Since years the market of mobile navigation systems is growing enormously. Within this paper the goals and first results of the joint project “Mobile Navigation with 3D City Models” (MoNa3D; http://www.mona3d.de) are introduced. The project consortium consists of the University of Applied Science Stuttgart (coordinator), the University of Applied Science Mainz, the University of Bonn and the fo...
