One of the most obvious technologies behind Location Based Services (LBS) is positioning, with the most widely recognized system being the Global Positioning System (GPS). There are, however, other means of positioning in addition to GPS. These other technologies are network based positioning and typically rely on various means of triangulation of the signal from cell sites serving a mobile pho...

The paper starts by sketching the key modes of spatial data analysis (point pattern, continuous surface, areal/lattice), and how they fit into legacy GIS data models. Based on development work with the GRASS release 5 team (GRASS 5 is GPL), status is reported for using R in the analysis of sites (point) data and for raster data, as well as using R as an intermediate analytical environment for i...

Abstract. User Oriented Geographical Information Systems, a recent adaptation of classical GIS concepts to everyday usage, are becoming more and more present in the web landscape. Recent developments show the need of adding higher semantic levels to the existing frameworks, to improve their usage, as well as to ease scalability. We point out limits of actual examples, related to handling hetero...

Combined research in the fields of Geographical Information Systems (GIS), transportation modelling and traffic systems has in fact finally reached the point where paths should overlap and continue in better unison between these different domains. This paper introduces methodological and experimental results of several integrated projects that include traffic monitoring systems, GIS and several...

The geographical information system (GIS) revolution started in the mid 1980s and has since snread to all countries of the world. A GIS is a comput&software package that is concerned with the capture, storage, manipulation, query, display and analysis of any and all types of geographical information, (BLJRROUGH, 1986; CHORLEY, 1987; LAURINI & THOMPSON, 1992; ESRI, 1993). There are now many diff...

Non-relational databases are the common means of data storage in the Cloud, and optimizing the data access is of paramount importance into determining the overall Cloud system performance. In this paper, we present GAIA, a novel model for retrieving and managing correlated geo-localized data in the cloud environment. We survey and compare the existing models used mostly in Geographical Informat...

Place is a concept that can hardly be formally captured at the moment, as it unclear how instances of places represented and conclusions about practically drawn by technological means. Geographical Information Science scholars hence tend to use term ‘Place’ even when, in fact, they presume paradigm similar one assumed for Geometrical Space. As result, Space thematic information mostly treated s...
