The purpose of UbiPOL project is to develop a ubiquitous platform that allows citizens be involved in Policy Making Processes (PMPs) regardless of their current locations and time. However, literature highlights one of the foremost reasons that make citizens de-motivated in engaging themselves in policy making—the ignorance of germane policies and PMPs within the government organizations. It is highly suggested that while more citizens find connections between their everyday life activities and pertinent government policies, the more they become pro-active or motivated to be involved in PMPs. For this reason, UbiPOL aims to provide ‘context aware knowledge’ provision with regards to policy making, i.e. through UbiPOL enabling citizens in identifying any relevant policies along with other citizens’ opinion ‘whenever they want’ ‘wherever they are’ according to their everyday life pattern. As a result of this platform, citizens are anticipated to be more acquainted with the newest rele...

Türkiye'de ve dünyada perakende mağazacılıkta son yıllarda ortaya çıkmış ve bu sektörde önemli yeri olan bizim de çalışmamızın esas konusunu oluşturan yapı marketler bakım, tadilat, onarım ve montaja yönelik ürünlerde uzmanlaşmış mağazalardır. Yapı marketlerde yeni mağaza açma kararları alınırken öncelikli olarak ele alınması gereken konu lokasyon seçimidir. Yapı marketler için stratejik değere sahip olan lokasyon seçimi konumsal ve konumsal olmayan verilere dayanarak gerçekleştirilmektedir. Konumsal ve konumsal olmayan verilerin bir arada toplanması, analiz edilmesi ve görüntülenmesi ile Coğrafi Bilgi Sistemleri(CBS) karar destek sistemlerinde önemli bir araçtır. CBS'nin yerel ve merkezi ölçekte lokasyon belirleme çalışmalarında fizibilite rapor aracı olarak kullanılması uzun ve kısa vadeli geliştirilen yatırımlara önemli girdiler oluşturmaktadır. Mağaza lokasyonu için belirlenen konum, sonrasında mağazanın yapacağı bütün ticari aktivitelerin sürekliliğini belirleyecek değe...

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. This process is called as Multi Resolution Database (MRDB). It is an expensive job and needs advance knowledge about map generalization techniques such as simplification, amalgamation tasks. Existing spatial databases currently do not support this innovation. Current spatial databases only support some basic geometry types to model features and spatial operators/operands for determining geospatial measurements like distance, area, and length. MRDB has another usage domain called information drilling. Information drilling provides linking between spatial objects at different spatial databases. Unfortunately, there is no support for data drilling in current spatial databases. 
In this study, a multi resolution database concept is modeled and prototype applications are developed. Information drilling methodology between multiple spatial databases is constructed. This drilling scenario contains a scale based linked data retrieval features. Sample location is selected as Ankara, which is the capital city of Turkey. Schools, roads, districts and power transformers data have been used as example of different data layers. Server side application is created to serve services to clients by using Java Enterprise Edition (J2EE) technologies. Also a native mobile application is implemented for Android platform to demonstrate information drilling in MRDB concept in mobile domain.
