We present a set of algorithms that recovers detailed building surface structures from large sets of urban images containing severe occlusions and lighting variations. An iterative weighted-average algorithm is introduced to recover high-quality consensus facade texture. 2D and 3D methods are combined to extract microstructures, facilitating urban model refinement and visualization.

T his study investigates the factors affecting the demand for new residential buildings in urban areas of Iran during 1976-2010. The demand function for new residential buildings in urban areas was estimated and then the existence of a long-run relationship among variables of this function was studied using the Bounds testing of the Autoregressive Distributed Lag Co-integration procedure. The t...

Sensing systems for urban deployments are still in their infancy. An interesting unresolved issue is the precise role assumed by people within such systems. This issue has significant implications on where the complexity and main challenges in building urban sensing system reside. We discuss the two endpoints of the spectrum of conscious human involvement, namely participatory sensing and oppor...

This paper will show one way to generate land use maps from register data. The register data used here is the Danish Building and Dwelling Register (BBR). The thematic result map showing urban land use will be based on a regular grid net with cell size of 100 m by 100 m. Each cell will be classified, based on the information on the buildings falling inside that cell. This paper will also presen...

This article describes the relationship between Urban Civil Engineering and other domains, specifically the hydrographic domain. The process of building HydrOntology and the portion of the model relating to urban features are described. This ontology emerges with the intent of settling as a framework in the GI domain, very closely interrelating to Towntology.

In addition to photovoltaic and wind systems, nowadays in-pipe water to wire power systems are becoming particularly interesting for the integration of renewable resources at urban and building scale because of the potential to harness clean energy from excess head pressure in urban and domestic water pipelines. Able to operate across a wide range of head and flow conditions, these particular m...

The proposed paper examines strategies whose aim is to counter the all too often sighted process of abandonment that characterizes contemporary cities. The city of Nicosia in Cyprus is used as an indicative case study, whereby several recent projects are presented as capitalizing on traditional cultural assets to revive the downtown. The reuse of existing building stock as museums, performing a...

The paper describes two different methods for extraction of two types of urban objects from lidar digital surface model (DSM) and digital aerial images. Within the preprocessing digital terrain model (DTM) and orthoimages for three test areas were generated from aerial images using automatic photogrammetric methods. Automatic building extraction was done using DSM and multispectral orthoimages....

institutional synergy in urban management, as a collective feature is the byproduct of inter and intra institutional activities of urban organizations. it is consider gregarious action and as managerial phenomenon with feature of trust, participation. cooperation engagement, facilitation, mutual recognition and the network. this article scrutiny the capacity of inters intuitional synergy in urb...

The Urban Heat Island (UHI) effect is a welldocumented phenomenon, in which the airtemperature in an urban area is elevated relative to the regional air-temperature. This paper evaluates two recently developed methods for generating urban weather files from a rural station that account for microclimatic impacts on dry-bulb temperature and relative humidity. The two methods examined are computat...
