    Seamless Online Distribution of Amundsen Multibeam Data

    Get PDF
    Since 2003, all underway multibeam and sub-bottom data from the Canadian Coast Guard Ship Amundsen has been posted online within approximately six months of the end of each cruise. A custom interface allowing the user to access 15\u27 latitude by 30\u27 longitude mapsheets was implemented in 2006, allowing the user to download the bathymetric and backscatter data at 10 metre resolution. While this interface matched the underlying data management scheme implemented at the University of New Brunswick, the zoom and pan capability was at a fixed scale with limited contextual data. In the past few years, with the introduction of web-based geographic information systems (GIS) (e.g. Google Maps, Yahoo Maps, Bing Maps), there have been thousands of maps published online. These online GIS programs are a suitable platform to display the seven years of Amundsen coverage within the context of the GIS-served satellite imagery and allow the user to freely browse all data in a familiar interface. The challenge, however, for serving up third party data through these map engines is to efficiently cope with the multiple zoom levels and changing resolutions. Custom tiling software was developed to take all the raw data from the seven years of Amundsen (and others\u27) multibeam coverage and convert it into multiple scale resolution images suitable for interpretation by Google Maps. The images were stored in a pyramid structure utilizing Google\u27s map projection and uniquely named to reflect their georeferencing and resolution. This image pyramid is then accessed by Google Maps according to the user\u27s current zoom level to optimize visualization. This multi-resolution data is served up on demand from the University of New Brunswick for dynamic overlay on Google\u27s satellite data. This web interface allows any interested parties to easily view multibeam and sub-bottom data from the Pacific Ocean through the Canadian Arctic Archipelago and into the Atlantic Ocean. The broad overview helps to understand regional trends and then focus on areas of interest at high resolutions to see particular features. The web interface also provides a link to the 15\u27 by 30\u27 mapsheet model with full source traceability

    Social Capital Made Explicit: The Role of Norms, Networks, and Trust in Reintegrating Ex-combatants and Peacebuilding in Liberia

    Processes for Disarmament, Demobilization and Reintegration (DDR) are a fundamental component in peacebuilding. While disarmament can be relatively straightforward, reintegration is more complex and has varying degrees of success. Economic factors tend to be the focus, neglecting social reintegration in its fullest sense. This article draws on two sets of related field research data (collected in 2007, 2010 and 2011) in Liberia to highlight the role of social capital in shaping DDR outcomes. This is an important factor in the reintegration of ex-combatants, in terms of establishing and testing norms, engaging social networks, and building relationships and trust. These components of social capital are directly influenced by the reintegration experience, and in turn have a significant role in translating reintegration into peacebuilding. In addition, building on pre-existing social structures such as family connections, religious or community groups, and trading networks can in fact contribute to successful reintegration. When DDR initiatives fail, these structures are often the only way an ex-combatant has of reintegrating

    Transforming our world:implementing the 2030 agenda through Sustainable Development Goal indicators

    No full text
    The United Nations' 2030 Agenda for Sustainable Development recognizes violence as a threat to sustainability. To serve as a context, we provide an overview of the Sustainable Development Goals as they relate to violence prevention by including a summary of key documents informing violence prevention efforts by the World Health Organization (WHO) and Violence Prevention Alliance (VPA) partners. After consultation with the United Nations (UN) Inter-Agency Expert Group on Sustainable Development Goal Indicators (IAEG-SDG), we select specific targets and indicators, featuring them in a summary table. Using the diverse expertise of the authors, we assign attributes that characterize the focus and nature of these indicators. We hope that this will serve as a preliminary framework for understanding these accountability metrics. We include a brief analysis of the target indicators and how they relate to promising practices in violence prevention. </p
