  • Giardiasis in the United States – an epidemiologic and geospatial analysis of county-level drinking water and sanitation data, 1993–2010

    Giardiasis is the most commonly reported intestinal parasitic infection in the United States. Outbreak investigations have implicated poorly maintained private wells, and hypothesized a role for wastewater systems in giardiasis transmission. Surveillance data consistently show geographic variability in reported giardiasis incidence. We explored county-level associations between giardiasis ...

  • European Agrochemicals Geospatial Loss Estimator: Model Development and Applications

     The CAP reform by decoupling subsidies from production levels and liking them to the protection of the environment is promoting a cleaner agriculture and a more sustainable use of resources. Agricultural subsidies are now linked to application of statutory minimum requirements (SMR) and cross compliance. Farmers willing to go beyond SMR can get additional payments through Rural Development ...


  • Geospatial water quality assessment system for the Sg. Buloh river basin in Malaysia

    Assessment of pollution risk requires the assimilation of spatio-temporally variable data on water quality parameters. This paper describes a GIS user-interface program coupled with a water quality index (WQI) model that was developed and built to assess water quality in the Sg. Buloh river basin. Fifty-two water sampling stations were selected for this study, and the WQI model considers ...

  • A framework for accurate geospatial modeling using image ranking and machine learning

    There is a large class of modeling problems where the complexity of the underlying phenomena is overwhelming and hence the accuracy of mathematical models is limited. Our approach to this class of problems is to design frameworks that bring together physically based and data-driven models, and incorporate the tacit knowledge of experts by providing visual exploration and feedback capabilities. ...

  • Development of 3D Geospatial Models to Support Environmental Restoration Activities at Technical Area 21, Los Alamos National Laboratory, New Mexico

    Technical Area 21 (TA-21) is a former processing area located on a 0.5 square mile mesa top at Los Alamos National Laboratory (LANL), New Mexico. A series of threedimensional (3D) geospatial models were developed to support ongoing and future environmental restoration activities. Mining of lithologic, geophysical, infrastructure, and analytical data sets was completed to construct 3D site ...

  • WaterML2.0: development of an open standard for hydrological time-series data exchange

    The increasing global demand on freshwater is resulting in nations improving their terrestrial water monitoring and reporting systems to better understand the availability, and quality, of this valuable resource. A barrier to this is the inability for stakeholders to share information relating to water observations data: traditional hydrological information systems have relied on internal custom ...

  • Report of International Workshop on Spatial Data Infrastructures` Cost-Benefit / Return on Investment

    This report provides a summary of the outcomes of a two-day workshop organized by the Joint Research Centre of the European Commission in partnership with the US Federal Geographic Data Committee, GeoConnections Canada, and the Geoide Network. This was the first meeting specifically dedicated to assessing the socio-economic impacts of Spatial Data Infrastructures (SDIs), and for this purpose ...


  • Molecular techniques and data integration: investigating distribution system coliform events

    A retrospective analysis of coliform events in a drinking water distribution system was conducted. A total of 13 coliform isolates with specific geographic/sampling records were analysed using microbial source tracking (MST) to establish genetic (based on DNA) and phenotypic (based on substrate utilization) relatedness between isolates, and a data integration approach (geo-spatial and event ...

  • Evaluation of NASA satellite- and model-derived weather data for simulation of maize yield potential in China

    Use of crop models is frequently constrained by lack of the required weather data. This paper evaluates satellite-based solar radiation and model-derived air temperature (maximum temperature, Tmax; minimum temperature, Tmin) from NASA and their utility for simulating maize (Zea mays L.) yield potential at 39 locations in China's major maize-producing regions. The reference data in this evaluation ...

  • Data Sharing – a Case of Shared Databases and Community Use of On-Line GIS Support Systems

    Data management is becoming increasingly simple and complex at the same time. The challenge is to effectively use the increasing number of tools available to manage increasing amounts of environmental information for purposes of data capture, analysis, display, sharing and storage. Government is no longer the main collector and provider of data. Community groups possess vast amounts of data ...

  • A unified index structure for efficient enforcement of spatiotemporal authorisations

    Uncontrolled dissemination of geospatial data may have grave implications on national security and personal privacy. Geospatial data can be considered sensitive based on attributes such as the location, resolution and the time of capture, etc. As such, authorisations associated with this data also possess spatial and temporal attributes. The main contribution of this paper is to improve the ...
