  • 35 - VGI and Beyond: from Data to Mapping
    Antoniou, V., Capineri, C. and Haklay, M., 2018. VGI and Beyond: From Data to Mapping. in: A.J. Kent and P. Vujakovic (Eds.), The Routledge Handbook of Mapping and Cartography. Abingdon: Routledge, pp. 475 - 488 35 - VGI and Beyond: From Data to Mapping Vyron Antoniou, Cristina Capineri and Muki (Mordechai) Haklay This chapter will introduce the concept of Volunteered Geographic Information (VGI) within practices of mapping and cartography. Our aim is to provide an accessible overview of the area, which has grown rapidly in the past decade, but first we need to define what we mean by VGI. Defining VGI In a seminal paper published in 2007, Mike Goodchild coined the term Volunteered Geographic Information (VGI) in an effort to describe ‘the widespread engagement of large numbers of private citizens, often with little in the way of formal qualifications, in the creation of geographic information’ (Goodchild, 2007: 217). At that point, rudimentary crowdsourced Geographic Information (GI) was created and disseminated freely with the help of innovative desktop applications (e.g. Google Earth) or web-based platforms (e.g. Wikimapia, OpenStreetMap). By crowdsourcing we refer to the action of multiple participants (sometimes thousands or even millions) in the generation of geographical information, when these participants are external to the organization that manages the information and are not formally employed by it. Since then a lot has changed and VGI now has a deep and broad agenda that ranges from implicitly contributed GI through social networks to rigorously-monitored citizen science projects. However, before we continue the discussion on this subject, it is necessary to shed light onto the key factors that have helped to create this phenomenon.

A reliable geocoding system that can effectively return any location on earth with sufficient accuracy is desired. This study is motivated by a need for a geocoding system to support university campus applications. To this end, the existing geocoding systems were examined. Address-based geocoding systems use address-matching method to retrieve geographic locations from postal addresses. They present limitations in locality coverage, input address standardization, and address database maintenance.

Almost everyone in the world uses mapping information, whether or not one realizes it. Almost every mobile phone now has location services and every event and object on the earth has a location. The use of this geospatial location data has expanded rapidly, thanks to the development of the Internet. Huge volumes of geospatial data are available and daily being captured online, and are used in web applications and maps for viewing, analysis, modeling and simulation. This paper reviews the developments of web mapping from the first static online map images to the current highly interactive, multi-sourced web mapping services that have been increasingly moved to cloud computing platforms. The whole environment of web mapping captures the integration and interaction between three components found online, namely, geospatial information, people and functionality. In this paper, the trends and interactions among these components are identified and reviewed in relation to the technology developments.

  • Abstract Utilization of Crowdsourcing And
    ABSTRACT UTILIZATION OF CROWDSOURCING AND VOLUNTEERED GEOGRAPHIC INFORMATION IN INTERNATIONAL DISASTER MANAGEMENT by Julaiti Nilupaer Large-scale disasters result in enormous impacts on vulnerable communities worldwide, and data acquisition has become a major concern in this time-critical situation: the limitations of geospatial technologies impede the real-time data collection, also the absent or poor data collection in some regions. With the current advances of Web 2.0, crowdsourcing and Volunteered Geographic Information (VGI) have become commonly used. As a potential solution to fill the gap of real-time geographic data, crowdsourcing and VGI enable timely information exchange through a voluntary approach and enhance amateur citizen participation. Importantly, such geographic information can substantially facilitate emergency coordination by fulfilling the needs of impacted communities and appropriately allocating relief supplies and funds. My research interest centers on the utilization of crowdsourcing and VGI for disaster management. Particularly, I work to explore their potential value and contributions by reviewing two notable and destructive disaster events as case studies: the 2011 Tohoku Earthquake and Tsunami, and the 2013 Typhoon Haiyan. In addition, I examine the challenges of this information and seek potential solutions. This research aims to contribute a comprehensive qualitative analysis of how Volunteer and Technical Communities (V&TCs) have used crowdsourced data and VGI to enhance the coordination of disaster management.

  • March – April 2021
    Over Thirty Years Reporting on NASA’s Earth Science Program National Aeronautics and The Earth Observer Space Administration March – April 2021. Volume 33, Issue 2. The Editor’s Corner Steve Platnick EOS Senior Project Scientist The Biden Administration has taken an important step in pursuit of its climate science objectives for NASA, creating the new position of senior climate advisor. Gavin Schmidt [NASA’s Goddard Institute for Space Studies (GISS)] has been appointed to serve in the role in an acting capacity until a permanent appointment is made. Schmidt is eminently qualified for the position having served as Director of GISS since 2014 with a research career focused on climate modeling, paleoclimate, and climate change detection and attribution. In his role as climate advisor, Schmidt will “advocate for NASA climate investments in the context of broader government agendas and work closely with the White House Office of Science and Technology Policy and the Office of Management and Budget.”1 My congratulations to Schmidt for this well-deserved inaugural appointment. This issue’s feature article focuses on NASA’s DEVELOP National Program, which is part of the Earth Science Division’s Applied Sciences Program Capacity Building program. DEVELOP strives to bridge the gap between science and society by demonstrating the use of NASA Earth Science data in environmental decision making. The program facilitates 10-week experiential learning opportunities, where participants work directly with partner organizations to build skills and knowledge around geospatial tools and Earth observation data. Traditionally DEVELOP conducts three project terms per year (Spring, Summer, Fall), with participant teams working from one of the program’s 11 host locations across the country (see Figure 1 on page 4 of this issue) on feasibility projects addressing environmental and public policy issues.
