Rapid development has promoted the 3D land use in the urban environment with the increasing requirements of the complex interweaving, such as dwellings, commercial areas, public transportation and urban utilities and infrastructure.3D cadastral object are features which concern unban planning, land resource and real estate of municipalities, whether they are on, obove or below the earth’s surfa...

New approach to cartographic modeling based on integration of scientiic visualization and computer cartography is presented. This approach moves cartography from 2D static maps to cartographic modeling of landscape as a complex dynamic system in 3D space and time. visualization INTRODUCTION As the result of a revolution in technologies for collection of information about the Earth, large volume...

In the face of the broad political call for an ―energy turnaround‖, we are currently witnessing three essential trends with regard to energy infrastructure planning, energy generation and storage: from planned production towards fluctuating production on the basis of renewable energy sources, from centralized generation towards decentralized generation and from expensive energy carriers towards...

GIS as we know it is traditionally a two-dimensional static representation of space, closely related to the paper maps that were its inspiration. While various attempts have been made to define a “3D GIS” or a “Dynamic GIS”, in recent years other disciplines have moved much faster in this direction – notably some parts of computer science, computer graphics and game development. This paper look...

The integration of digital terrain models (DTM) in geographic information systems (GIS) implies automatically an extension of the GIS reference surface and its queryspace. It is trivial that a DTM is the natural boundary representation of theearth's surface. Man-made objects, for instance houses, bridges, dams should be considered in a second step because these objects cannot be represented wel...

In this paper we introduce the concept and the implementation of an Emergency Route Service 3D (ERS3D), which is based on the already established OGC Standards OpenLS and which further covers the following two aspects: Firstly, the possibility to bypass restricted areas or closed streets during disaster situations and secondly the ability to return a 3D route geometry that can be integrated int...

On May 12, 2008 a large earthquake occurred in Wenchuan, resulting in significant casualties and enormous property loss, and shocked the world. Then the Tangjiashan barrier lake caused by earthquake, made a serious threat to 1.3 million people living downstream. From its formation to being successfully disposed, the entire emergency management of Tangjiashan barrier lake lasted about a month. I...

Within the paper the automatic matching of existing GIS data to airborne SAR scenes for georeferencing is discussed. For this purpose simulated SAR images are generated based on the available GIS objects using a SAR simulator. These simulated scenes are matched against the captured SAR image in order to detect the given GIS objects in the SAR scene. The feasibility of the approach is demonstrat...

This paper presents a Geographic Information System (GIS) based cost estimation methodology, which may be helpful in increasing the productivity of quantity estimator by reducing the manual work in quantity takeoffs. Proposed methodology also eliminates missing or duplication of various items of work by visualizing each components corresponding to the items in three dimension (3D). Several scri...

Architectural heritage must be conserved by using contemporary approaches. Conserving the historical buildings depend on appropriate measurements and data related to their life history. At this stage, digital photogrammetric techniques and GIS (Geographical Information System) integration would be one of the best solutions. GIS has a capability to integrate and update graphic and non-graphic da...
