We present a study in which we seek to interpret spatial references that are part of in-situ route descriptions. Our aim is to resolve these references to actual entities and places in the city using a crowdsourced geographic database (OpenStreetMap). We discuss the problems related to this task, and present a possible automatic reference resolution method that can find the correct referent in ...

Given the ubiquitous nature of infrastructure networks in today’s society, there is a global need to understand, quantify, and plan for the resilience of these networks to disruptions. With the development of transport infrastructure, vulnerability analysis is a core process of man-made systems safety management. The main purpose of the paper is to identify the critical road sections and inters...

Volunteered Geographic Information (VGI), as a special subset of crowdsourcing, has provoked interest from many scientific disciplines and industry in the past few years. OpenStreetMap (OSM) is the most famous and well supported example of a VGI project on the Internet today. As a technology, Digital Earth (DE) offers immediate access to enormous quantities of data and information, referenced b...

The OpenStreetMap (OSM) project, founded in 2004, has gathered an exceptional amount of interest in recent years and counts as one of the most impressive sources of Volunteered Geographic Information (VGI) on the Internet. In total, more than half a million members had registered for the project by the end of 2011. However, while this number of contributors seems impressive, questions remain ab...

Geographic networks are everywhere, as rivers, power grids and street networks. Computational and mathematical tools for traditional analysis of graphs and recent studies on complex networks have been incorporating the geographic component. This article presents a general tool, in development process, for visualizing geographic networks: the GIS4Graph tool. An application is presented in the an...
