  • 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 ...

  • Automatic mapping in emergency: a geostatistical perspective

    In the case of a severe nuclear accident, radionuclides may be released into the atmosphere and contaminate large areas. Radiological maps are obtained after converting local measurements into continuous information in space. Ideally, the mapping process should be fully automatic and provide information in real time. This paper is presenting the results obtained from two statistical exercises ...

  • 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 ...
