Information technologies have achieved an important role in archaeology. The management, research and exchange of the large amount of data gathered from archeological sites needs the tools of information technologies. The web based GIS combines the advantages of both GIS and the Internet technologies. This system can be used as a tool that helps to support the management of information for archaeological sites and provides support functions for specialists.This web based system can hold many types of archaeological site data from small excavation campaigns to large sites. The system consists of a relational database, a web server, and a GIS mapping server. Google Maps Server is used as a GIS mapping server in this study. The client computers require only the availability of a proper browser that supports javascript and ajax technologies. With this system, Google Maps can be used as an archaeological research tool for everybody interested in archaeology. In a general, everybody can reach the system using their web browsers in order to search and retrieve information regarding archaeological sites. This system also enables specialists to upload, search and share archaeological data. The aim of this study is to provide easy and simple access to the GIS related archaeological site information in Turkey, using a web based and user friendly interface and share the information the information with specialists all over the world.

&lsquo / Bag&rsquo / settlements have been a part of dynamic spatial systems, which seasonally depend on and reciprocally interact with Anatolian towns throughout centuries. This thesis presents the transforming setting of &lsquo / bag&rsquo / settlements related to changing values and meanings through an ontological assessment. Therefore, the thesis assumes that the main values of spatial organization, farmland pattern, ecological formation, settlement character, socio-cultural structure and lifestyle of the inhabitants constitute the unique entity of &lsquo / bag&rsquo / settlements. In time, the pressures of changing socio-economic conditions have destroyed the interaction between Anatolian towns and &lsquo / bag&rsquo / settlements. The thesis explains the changing role of &lsquo / bag&rsquo / settlements, changing and conflicting land uses and the loss of unique &lsquo / bag&rsquo / character in the case of Mugla-Karabaglar. Karabaglar is a &lsquo / bag&rsquo / settlement in the southwestern Turkey, where Mugla town residents live seasonally. It is a third grade natural site, the unique character, the natural and cultural assets and the lifestyle of which must be preserved. However, with transformation of the main values, meanings and practices, Karabaglar could no longer perpetuated its initial existence of being. Karabaglar is significant for two reasons: it has natural and cultural beings that need to be conserved, and as it still goes through a transformation process. The master&rsquo / s thesis of the author evaluated conservation plan of Karabaglar. Differently, this doctoral thesis evaluates the dynamics of the spatio-temporal transformation process in Karabaglar. It presents the changing role and significance of Karabaglar within the town-country continuum. This situation brings forward the conservation problematic of the character, landscape and uniqueness of Karabaglar. Within this respect, the thesis contributes to the literature of &lsquo / bag&rsquo / settlements in terms of defining their being and changing role throughout the history.

Today, population census results are not only fundamental for population counting but also for providing various information to many organizations and people who make research and take decisions about human-related issues. However, statistics produced on the basis of administrative divisions in Turkey are inadequate to meet the needs of most In this study, a new census geography is aimed for Turkey using Geographic Information Systems and Multi Criteria Decision Making methodologies. This new census geography is for statistical purposes only, independent from legal boundaries and generated by the concept of small area statistics. New rules and methodologies are created by taking the United States and the United Kingdom systems as models to reach to the main aim, and then they are applied on a case study area, &Ccedil / ankaya District in Ankara. Through this application process, firstly all the collected graphical and nongraphical raw data are geo-referenced and combined in a common geodatabase. Secondly, this geodatabase is used to understand the differentiation of quality of life indicators across the case study area. This pattern is then used to draw the boundaries of small statistical units of the new census geography in terms of the previously defined population sizes. In conclusion, a nationwide standard census geography hierarchy, which ranges between national level at the top and block level at the bottom, is proposed for use in 2010 Population Census and afterwards.
