The main objective of this study is to determine main activity locations and correlation between different artifact types in an archaeological site with geographical information systems (GIS) and spatial data analyses. Knidian amphora workshops in Dat&ccedil / a peninsula are studied in order to apply GIS and spatial statistical techniques. GIS capabilities are coupled with some spatial statistical software and spatial data analysis steps are followed. Both point and area datasets are examined for the effective analysis of the same set of spatial phenomena. Visualizing the artifact distribution with the help of GIS tools enables proposing hypotheses about the study area. In exploration part of the study, those assumptions are tested and developed with the help of explorative methods and GIS. The results are discussed and assessed in terms of archaeological framework. Finally the results are compared with the archeo-geophysical anomalies and excavation results.

This study is about uncertainty medelling for vector features in geographic information systems (GIS). It has mainly two objectives which are about the band models used for uncertainty modelling . The first one is the assessment of accuracy of GBand model, which is the latest and the most complex uncertainty handling model for vector features. Some simulations and tests are applied to test the reliability of accuracy of G-Band with comparing Chrisman&rsquo / s epsilon band model, which is the most frequently used band model among the others. The tests are realized with two cases, testing with digitized lines by people and testing with randomly created lines with gaussian random number generator algorithm. So, the results can be examined in two different ways. The second aim of this thesis is development of band models for functional special curves. These functional curves are based on some mathematical models. Specifications of these curves are defined in the structure of Geographic Markup Language (GML) of Open GIS Consortium (OGC). They are arc, arc string, clothoid and cubic spline. Uncertainty for arc by three coordinates, arc string and cubic spline are modelled by G-Band. Arc by center point and clothoid are modelled by epsilon band. In this thesis, a commercial GIS API, GeoKIT is used to create the band geometries of functional curves, to perform some simulations and tests to make the comparison and to present the developed functionality as a desktop application. Band geomeiv tries are developed in the structure of API model which enable the functionality. Secondly, Matlab 2006a is used for technical computing to calculate multivariate normal cumulative density function (mvncdf) to be used in analyses and simulations.
