  • Detecting OSM Building Facades with Graffiti Artwork Based on Street View Images and Social Media using Deep Learning

    As a recognized type of art, graffiti is a cultural asset and an important aspect of a city’s aesthetics. As such, graffiti is associated with social and commercial vibrancy and is known to attract tourists. However, positional uncertainty and incompleteness are current issues of open geo-datasets containing graffiti data. In a newly published paper, we…

  • Usability of Flickr tags for land use/land cover attribution

    A new study has been published in the international open access journal Geo-spatial Information Science (GSIS, Taylor & Francis), that explores the land use/land cover (LULC) separability by the machine-generated and user-generated Flickr photo tags (i.e. the auto-tags and the user-tags, respectively), based on an authoritative LULC dataset for San Diego County in the United…

  • POI/ROI Discovery using Flickr geotagged photos

    In the era of big data, ubiquitous Flickr geotagged photos have opened a considerable opportunity for discovering valuable geographic information. Point of interest (POI) and region of interest (ROI) are significant reference data that are widely used in geospatial applications. A recently published study (Kuo et al 2018) study aims to develop an efficient method…

  • Monitoring and Assessing Post-Disaster Tourism Recovery Using Geotagged Social Media Data

    Tourism is a economically highly important industry. It is, however, vulnerable to disaster events. Geotagged social media data, as one of the forms of volunteered geographic information (VGI), has been widely explored to support the prevention, preparation, and response phases of disaster management, while little effort has been put on the recovery phase. A recently…

  • Towards using Volunteered Geographic Information to monitor post-disaster recovery in tourist destinations

    The aftereffects of disaster events are significant in tourist destinations where they do not only lead to destruction and casualties, but also long-lasting economic harms. The public perception causes tourists to refrain from visiting these areas and recovery of the tourist industry, a major economic sector, to become challenging. To improve this situation, current information…

  • European Handbook of Crowdsourced Geographic Information

    Recently, a new open access handbook edited by Capineri, et.al and supported by the European Commission – COST Action IC1203 (ENERGIC) has been published. This book focuses on the study of the remarkable new source of geographic information that has become available in the form of user-generated content accessible over the Internet through mobile and…

  • A review of volunteered geographic information quality assessment methods

    While Volunteered Geographic Information (VGI) is gaining more and more popularity and VGI datasets are being used in various projects, there are always concerns about the quality of them. During the past years several studies have been performed regarding VGI quality assessment by employing different methods/approaches. However, if one needs to evaluate the quality of…

  • gis.SCIENCE special issue GEOINFORMATIK 2013

    The issue 3/2013 (Vol. 26) of the journal gis.SCIENCE by Wichmann has been published. It contains selected full review paper (e.g. on context-aware 3D geovisualization or on the analysis of tourist activity from Flickr fotos) from the conference GEOINFORMATIK 2013, that was held at Heidelberg University this year. The cover features a screenshot from OSM-3D.org…

  • Road-based travel recommendation using geo-tagged images from social media

    Geotagged photos on social media like Flickr explicitly indicate the trajectories of tourists. They can be employed to reveal the tourists’ preference on landmarks and routings of tourism. Most of existing works on routing searches from social media are based on the trajectories of GPS-enabled devices’ users. We attempt to propose a novel approach in…
