Abstract
Geographic Information Systems (GIS) have an important effective role which has been clearly evident in various areas. GIS contributes greatly to the formulation and compilation of the available data in an organized manner that provides an easy and simple access to the required information, and significantly helps in taking the most appropriate decisions on the relevant matter. GIS has recently introduced revolutionary changes in the field of infrastructure assets management and utility mapping, the main focus of this study. Infrastructure facilities have always attracted the attention of various national governments, since such facilities are viewed as the nucleus of modern civilization .It has become an important criterion for judging the cultural and economic progress of the different societies. Investment in infrastructure has always been a major driver and decisive factor in the growth of nations. Economic and population growth has created an urgent need for investment in the basic infrastructure such as; water treatment facilities, sewer lines, utility grids, electricity, energy, etc. Utility mapping can be defined as the representation and documentation of the various utility elements in a graphical form. Underground utility mapping refers to the detection and positioning of pipes and cables buried beneath the ground, in addition to the identification of their spatial and descriptive data, which are completely invisible to the naked eye. Egypt has recently adopted the required technologies to establish integrated digital databases for the national infrastructure, so as to support and promote the sustainable developmental efforts. In this study, using GIS and Model Building technique in the field of infrastructure mapping, an automated alert system is pursued and established so as to automatically test the infrastructure maps and identify error locations and logical observations, according to prior data fed with the basic standards and rules, through which the validity of the distribution of different elements on the map can be judged. The operation ability of such a system would be of great help to those who deal with infrastructure maps, and can be used in the stage of introducing and reviewing utility networks data. It would also improve the speed of detecting errors that might be generated by the human factor, which would certainly enhance and accelerate the process of error control, and thus obtain maps with high accuracy and credibility that can be relied upon in conducting various operations; like the processes of query and analysis and so on. The thesis is divided into five chapters: introduction, geographic information systems and utility mapping, case study and check rules, building the model using ArcGIS ModelBuilder and finally conclusions and recommendations. Chapter 1: This chapter provides an introduction to the study, the question of the thesis, literature review, the research methodology, in addition to the importance and techniques of GIS. Chapter 2: The first section of chapter two discusses a brief form of GIS, while the second section discusses the infrastructure and utility mapping in some details. Chapter 3: This chapter introduces the study sample and checking rules; including an introduction to topology, its definition and relationship with GIS, and an example of its applications within the ArcGIS program. Chapter 4: It deals, in some details, with the available Model Builder technology through ArcGIS. Chapter 5: It highlights the conclusions which have been drawn from this research and summarizes the major findings. It also contains some suggestions for future works related to the subject matter.
