Use of 3D City GIS for Sustaining and reconstructing Cities

Abstract

Three-dimensional GIS modeling is growing rapidly with the evolving new technologies. It supports various applications and keeps these moving to a new direction for the geospatial community. Three-dimensional modeling is a real simulation of reality, especially if it is relatively accurate. On the other hand, the use of three-dimensional modeling in the GIS environment provides a flexible interactive system to provide the best visual interpretation processes, plannings and decision-makings. Modeling using the third dimension is one of the most important technologies and is most effective for the management of spatial data infrastructures and analysis. The aim of this work is to show, how to create the required projects to build or restructure modern cities, using 3D geographic information systems integrating digital photogrammetry techniques, and other spatial technologies. For our studies we have chosen the Al-Mogran Area as a Testbed, which is located in the State of Khartoum, being a meeting place for the White and Blue of Nile, and reflecting the importance of cultural life and tourism. Nevertheless, it is independent of any optimal ratio of geographical, economic and cultural locations. Therefore, this study aims at geographic analyses using modern techniques and reflecting the importance of three-dimensional modeling for buildings, such as housing, hotels, offices, being used by commercial markets, companies, leisure or health facilities. In addition, the infrastructures of modern municipal service providers are to be considered, to name here the distribution of electricity, gas, sanitary water and sewage pipes, which should be excellent. The experience of this research is the basis to enable the State and the decisionmakers and investors to have a clear vision for the future of this region. On display is the best-case scenario they can benefit from. This reverses the importance of three-dimensional modeling and its role in the development of cities. Hopefully, this experiment can be expanded to the entire state of Khartoum and the country as a whole.
