Interoperability between Geographic Information System (GIS) of different infrastructure companies is still a problem to be handled. Infrastructure companies deal with many operations as a part of their daily routine such as a regular maintenance, or sometimes they deal with unexpected situations such as a malfunction due to natural event, like a flood or an earthquake. These situations may affect all companies and affected infrastructure companies response to these effects. Responses may result in consequences and in order to model these consequences on GIS, GISs are able to share information, which brings the interoperability problem into the scene. The present research, aims at finding an answer to interoperability problem between GISs of different companies by considering contextual information. During the study, the geographical features are handled as the major concern and interoperability problem is examined by targeting them. The model constructed in this research is based on the ontology and because the meaning of the terms in the ontology depends on the context, ontology based context modeling is also used. v In this research, a system implementation is done for two different GISs of two

Positional uncertainty analysis using data uncertainy engine a case study on agricultural land parcels Urgancı, İlksen; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2009) Most of spatial data extraction and updating procedures require digitization of geographical entities from satellite imagery. During digitization, errors are introduced by factors like instrument deficiencies or user errors. In this study positional uncertainty of geographical objects, digitized from high resolution Quickbird satellite imagery, is assessed using Data Uncertainty Engine (DUE). It is a software tool for assessing uncertainties in environmental data; and generating realisations of uncertain da...
Evaluating geoportals Con, Eren; Akyürek, Sevda Zuhal; Department of Geodetic and Geographical Information Technologies (2014) The idea of sharing data is the most important element for geographic information infrastructure, data standards and quality. To achieve this; building spatial data infrastructure, sharing and the presentation of the data concepts are available throughout the world. Following the production of data, there are specific standards such as ISO TC/211, INSPIRE and OGC to define rules and procedures of data sharing. Following the production of the data within certain standards, it is important to reach the data t...
Multi resolution spatial database for mobile applications İnal, Kamil; Akyürek, Sevda Zuhal; Department of Geodetic and Geographical Information Technologies (2013) Nowadays, in Geographical Information Systems (GIS), usage of Location Based Services (LBS) has been exploded and map based web/mobile applications have been rapidly increased. With the occurrence of this event, spatial data accessing, storing and querying operations have become more important than before. There is a new challenge, which is about the efficient access to geographical map data at multiple detail of level. Multiple detail of level is a process of derivation of a map at a particular resolution....
Weighted multi-visibility analysis on directional paths Şeker, Çağıl; Toprak, Vedat; Department of Geodetic and Geographical Information Technologies (2010) Visibility analysis is an important GIS tool that is used in a diverse array of disciplines ranging from earth sciences to telecommunications. Multi-visibility, as a cumulative type of visibility, combines many point-to-point results into a multi-value array. Points, lines, or areas can be used as sources or targets; and the combined values can be calculated in both ways. Through multi-visibility, a special 2.5D visibility value surface can be constructed over a digital elevation model. The effectiveness of...
GIS-based stochastic modeling of physical accessibility by using floating car data and monte Carlo Simulations Ertuğay, Kıvanç; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2011) The term physical accessibility has widely been used by geographers, economists and urban planners and basically reflects the relative ease of access to/from several urban/rural services by considering various travelling costs. Numerous accessibility measures, ranging from simple to sophisticated, can be found in the GIS based accessibility modeling literature. However, whether simple or sophisticated, one of the fundamental shortcomings of the current GIS-based accessibility measures is that they are gener...
