Laser altimetry is a valuable data source for the production of 3D city models. For applications of 3D city models that are to provide a realistic impression of the urban environment, modelling of the buildings only is insufficient. This paper presents methods for the reconstruction of the street surfaces by combining airborne laser data with 2D information from a cadastral map. Locations of tr...

The neighborhood has been used as a sampling unit for exploring variations in health outcomes. In a variety of studies census tracts or ZIP codes have been used as proxies for neighborhoods because the boundaries are pre-defined units for which other data are readily available. However these spatial units can be arbitrary and do not account for social-cultural behaviors and identities that are ...

An important activity in urban three-dimensional (3D) mobile navigation is browsing the buildings in the environment and matching them to those in the 3D city map. There are different factors affecting the recognition process such as changes in the appearances of buildings, weather, and illumination conditions. The current aim was to study the salience of different types of visual cues in the r...

A techno-economic heating energy system model for Vienna (Austria) is developed. Based on an existing solar potential map, different solar heat strategies can be evaluated economically and ecologically. The resulting share of installed solar heat units for every building is displayed in a 3D city model. This 3D model allows city planners to study the spatial impact of these strategies. Results ...

spatial and stable view is the main and inevitable principle of city physical development progmming. along this approach, and because of social, economic and natural requirements, we studied the physical development of eghlid city.the development of eghlid city is limited because of being located in a closed mountainous location. indeed, negative and destructive consequences follow improper pro...

Even though fewer people die as a result of fire than other natural disasters, such as earthquake, flood, landslide, etc., the average loss of property due to fire is high. Kathmandu Metropolitan City is becoming more vulnerable to fire due to haphazard urbanization and increase in population. To control problems due to fire, systematic studies are necessary, including fire potential mapping an...

In order to reconstruct missing city including houses, roads and other objects using historical maps, an efficient city modeling is still issue which resolved. In particular, 3D modeling of houses is important issue since houses are important component of historical city model. With this motive, an efficient method for reconstruction of historical city using historical map is proposed by the au...
