Abstract Constructing a public building is a process that consumes a lot of funds, and any insufficiently studied decisions concerning this issue may lead to losses and consequently non-optimum usage of these funds. This returns mainly to lack of studies, exaggeration in simplifying complicated issues and ignoring relevant criteria and advanced techniques and tools that must be used. An important example is the site selection process of a new proposed public building where many important factors such as safety factors, environmental factors, services / utilities factors, site geotechnical factors, topographic factors, demand factors, regulations / constraints factors and site status factors may be ignored. The whole issue is reduced in an only one factor which is the availability of land parcels regardless of the suitability of the site and the need of a public building in that place. This may result in spending a lot of money to build a new public building which may show later unsuitability for its function and a lot of complaints by its users and consequently bad performance or even failure from the functioning point of view. For all what was previously mentioned, it was very important to study how to carry out the process of optimum site selection for public buildings in a proper and efficient way. The thesis aims to integrate several relevant advanced sciences and techniques such as Information Technology (I1’), Geographic Information Systems (GIS), Remote Sensing (RS), demography, and Global Positioning Systems (GPS) through making the best use of their advantages and tools to support the optimum site selection for public buildings. One of the main objectives of the thesis is to follow an active and logical policy to carry out the process of optimum site selection for public buildings within urban areas - where availability of land parcels is the basic factor through building an optimum site suitability and evaluation model that evaluates all the available land parcels and identifies the most suitable one that best fulfils the relevant factors resulting in an optimum site selection for the public building within the available land parcels. This takes place through a pilot project using the spatial and surface analysis techniques to produce categorized and total suitability maps in order to determine and evaluate the most suitable sites for constructing the public building. Another main objective is to follow an effective and logical policy to carry out the process of optimum site selection for public buildings within rural areas - where required candidate sites can be allocated - through building an optimum site suitability and selection model that takes into consideration all the possible relevant site selection factors, weighting them, excluding unsuitable areas and evaluating the candidate sites resulting in an optimum site selection for the public building. This takes place through a pilot project using spatial and surface analysis techniques in addition to spectral analysis to produce categorized and total suitability maps in order to determine the most suitable sites for constructing the public building. Network analysis is used later for optimizing site selection. The thesis consists of seven chapters starting with the introduction, then the three chapters representing the theoretical component that discusses the three main issues needed for the latter applications. Tbese are : Site selection criteria and evaluation, relevant data sources, models, and integration and finally GIS and RS fundamental analytic tools supporting the site selection process, then the two chapters representing the applications component are presented. Finally, the thesis ends with the summary, conclusions and recommendations. Keywords: Geographic Information Systems (GIS), Remote Sensing (RS), Information technology (IT), Global Positioning Systems CGPS), and Mapping. |
