An Analysis of Quality for Volunteered Geographic Information by Joel Clarence Howard Meier B.A., Geography University of Guelph, 2010 P.G. Dip, Centre of Geographic Sciences, 2011 THESIS Submitted to the Faculty of Arts Geography and Environmental Studies in partial fulfillment of the requirements for Master of Science in Geomatics Wilfrid Laurier University © Joel Clarence Howard Meier 2014 ii Abstract Volunteered geographic information is a new and growing source of information for generating accurate maps which display various landscapes and populations. This thesis discusses the definitions, history and theory of VGI with an eye toward its practical applications for geographic and environmental research. A major issue with the practical application of VGI is uncertainty about how to measure and characterize data quality. This thesis investigates issues of data quality for VGI by using the International Standards Organization framework for data quality assessment for geographic information. -
Standardization, Modeling and Implementation of Points of Interest – a Touristic Perspective
International Journal of u- and e- Service, Science and Technology Vol.6, No.6 (2013), pp.59-70 http://dx.doi.org/10.14257/ijunesst.2013.6.6.07 Standardization, Modeling and Implementation of Points of Interest – a Touristic Perspective Thomas Spangenberg Faculty of Automation and Computer Science, Harz University of Applied Sciences, Wernigerode, Germany [email protected] Abstract Points of Interest (POI) are crucial content elements in various applications and services. Numerous use cases (e.g., navigation, mapping, or location-based services) causes that POI data is described in different, mostly proprietary formats. That prevents the use of POI across application boundaries. One reason is that there is no acknowledged POI data standard. However, the World Wide Web Consortium (W3C) released a promising working draft – the POI Core data model. Within this paper, the POI Core is analyzed and an XML schema for POI is presented from a touristic perspective. This schema is implemented using the GPS Exchange Format and a novel GPX extension. The extension enables a significantly improved inclusion of context information into POI descriptions. Finally, a concrete example of a touristic attraction, which is a specialization of POI, will be presented to show the value of the novel approach. Keywords: Data Modeling, GPS Exchange Format, Points of Interest, Standardization, Tourism 1. Introduction Points of Interest (POI) are considered to be the most fundamental requirement of any spatial data infrastructure [19]. They are used in various applications and services, such as navigation systems, mapping, augmented reality, tourist information systems, mobile guides, social networks, recommender systems, location-based services, and many others.
