Lecture Notes in Computer Scienceilize and value their surroundings. There is increasing interest in mining information from geo-referenced user-generated content (UGC) and volunteered geographic information (VGI) to gain new insights into how people describe and delimit urban places such as neighbourhoods and vernacular landmarks

Tao Hong,Xiangyang Guo,Zeren Zhang,Jinwen Mahree different components of data quality: coverage, density, and user-heterogeneity. Two popular sources of passive VGI are used for initial testing of the metric: Twitter and Flickr. We compare the component and aggregate measures for different simulated point processes and demonstrate the propert

Lecture Notes in Computer Sciencesues are usually related to how roads are ‘drawn’ (modeled) by OSM contributors. First of all, this paper identifies several issues in tagging and modeling OSM road network by case studies, and also gives suggestions for contributors and routing service providers. As a key contribution, this paper p

Lecture Notes in Computer Scienceowever, short-term comparative explorations, especially those considering all levels of the nationwide road hierarchy, have been neglected. This study aims to create a comprehensive road change database of the United States through compilation of U.S. Census Bureau TIGER/Line GIS datasets from 2008
