The Use of European Internet Communication Properties for IP Geolocation

IP Geolocation is a term used for finding the geographical location of an IP node. In this paper, we study the Internet communication properties and their use for client-independent Geolocation - finding the location without assistance of the node being located. We present and discuss the communication properties dependence on geographical aspects such as the geographical distance, differences between the source and destination country, and country population density and country ICT development index. For the study, we used a large set of data captured between the nodes geographically distributed across Europe. Based on the results, we propose an algorithm for a final location estimation within the delimited geographical area. The proposed algorithm improves the location accuracy when compared with the current techniques

From GeoVisualization to visual-analytics: methodologies and techniques for human-information discourse

2010 - 2011The objective of our research is to give support to decision makers when facing problems which require rapid solutions in spite of the complexity of scenarios under investigation. In order to achieve this goal our studies have been focused on GeoVisualization and GeoVisual Analytics research field, which play a relevant role in this scope, because they exploit results from several disciplines, such as exploratory data analysis and GIScience, to provide expert users with highly interactive tools by which they can both visually synthesize information from large datasets and perform complex analytical tasks. The research we are carrying out along this line is meant to develop software applications capable both to build an immediate overview of a scenario and to explore elements featuring it. To this aim, we are defining methodologies and techniques which embed key aspects from different disciplines, such as augmented reality and location-based services. Their integration is targeted to realize advanced tools where the geographic component role is primary and is meant to contribute to a human-information discourse... [edited by author]X n.s
