  • New Jersey Uses GIS, EQuIS to Collect Site Remediation Data

    Using GIS To Manage Remediation Data GIS holds great potential as a tool for managing environmental site remediation data. While using GIS to locate Superfund sites is commonplace, GIS has played only a minor role in the review and analysis of chemical data gathered during an investigation or monitoring activity. There are a number of reasons why GIS has not become commonplace in the ...

  • Integration of Subsurface Data Management and GIS to Facilitate Model Calibration

    Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...

  • Geographic information systems (GIS) for participation: the future of environmental GIS?

    The conventional uses of geographic information systems (GIS) in environmental management have been criticized for being undemocratic and avoiding the social dimension of these issues. To address these criticisms, new participatory approaches are being developed by the GIS community. These new techniques involve the integration of conventional spatial data and mental maps showing communities' (or ...

  • A GIS-based methodology to delineate aquifer recharge areas

    A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

  • Mapping the results of mobile network monitoring: a GIS solution

    Most of us are familiar with the 'can you hear me now' commercial - a spectacled technician from a major wireless carrier moves about with a dedicated team testing the voice clarity of the network. Geographic information system (GIS) technology (Foote and Lynch, 2011), together with the use of existing data collection hardware, allows analysts to map results of mobile networks both accurately and ...

  • 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 ...

  • Spatial analysis of water quality using a combination of GIS and statistical software

    GIS-based spatial analysis was combined with statistical analysis to process time varying water quality data. A data model was employed to manage the spatio-temporal data. The spatial data engine of ArcSDE was used to access the database. A data relationship model was developed to perform data communication between GIS and the statistical software. Visual Basic was used to construct links between ...

  • A GIS based air quality system for the Apulia region, southern Italy

    A GIS based air quality modelling system has been developed in Apulia region in the Southern Italy, to support local authorities in air quality management. Meteorological and dispersion simulations were performed for the year 2005. Predictions have been compared with concentration data from the air quality monitoring network. Results evidence a good correlation between predictions and ...

  • A decision support system for air quality management combining GIS and optimisation techniques

    This paper describes a multi-tiered approach to the design of plans and policies for urban environmental management, in particular air quality, as related to the energy and transportation sectors. The approach is based on the iterative combination of sectoral and global optimisation models, including a discrete multi-criteria approach, and spatially distributed air quality models. The approach ...

  • Study of water-table behaviour for the Indian Punjab using GIS

    The state of Punjab (India) has witnessed a spectacular increase in agricultural production in the last few decades. This has been possible due to high use of fertilizers, good quality seeds and increased use of water resources. This increased demand of water resources has resulted in extensive use of groundwater in the central districts of the state and surface water (canals) in South-West ...
