Title: A multipurpose utility model for Khartoum urban area Using GIS Analysis Techniques
Author: Abdelgiom, Mahmoud Abdelrahim; Gorani, Mohamed Ahmed; Mohammed, Gar Alnabi Ibrahim
Abstract: The main objective of this study is to design and develop a multi-purpose utility model for north of Khartoum area using techniques of Geographical Information System (GIS). Moreover, the study aims to investigate and identify the operational development systems employing integrated utility databases for facilities including water pipelines networks, sewage system, electric networks, and telephone and telecommunication networks and roads services. The second goal is to establish multi-purpose utility model to aid for management and development future plans as well as providing a requisite accuracy in a multi-purpose utility model case by design and maintenance errors resulting in great cost. The methodology of this study intends to establish a mutual global and a local datum base map comprising all utility services in study the area and to apply the GIS analysis techniques for the management and planning of these networks with the ultimate aim of achieving easy and fast operation, updating and maintenance of these networks. The software used is ArcGIS9.3 package for transformation of coordinates, vectorization, editing, Topology, retopology, addition of attribute data , and performance of spatial analysis. An urban study area (North of Khartoum) is selected from the topographical map prepared by Dr.M.A.Gorani and provided by the Sudan National Survey Authority (SNSA) at scale of 1:25000.It is demarcated by the Nile avenue from the North , AlImam AlHadi road from the South, the Armed Forces bridge from the East, and the White Nile bridge from the West.. The urban study area covers (5.94) km2. Reference spheroid for the coordinates of the study area is Clarke 1880, Universal Transverse Mercator (UTM) Projection. Grid zone is 36, and Adindan Datum. Constructing the database for the model requires scanning from a hard copy, transformation from machine coordinates to ground coordinates, transferring from raster to vector data, and then manipulating the database using a GIS software. The attributes were entered using the key board. This study shown that digital utility model analyses cannot be achieved by looking or carrying out analysis only in one dimensionality of GIS; need to employ multi-dimensional GIS to accomplish GIS-SA. It has shown how the various dimensionalities of GIS (2D, and 3D) can be used to accomplish specific tasks in multi-purpose utility model such as exchange data in different format and analysis of the utility model at both aggregated of services and disaggregated with data collected by the traditional and modern methods. The study concludes that a common control room should be established to mountain and manages the utility services network. Within this model the role of the GIS is to feed the system with the exact location of the break down using detectors of water and drainage pipelines.
