Contamination has a dramatic impact on the health of ecosystem and habitat suitability for the inhabited flora and fauna. The Environmental Protection Agency (EPA) mandates an ecological risk assessment (ERA) that evaluates the potential adverse impact of any anthropogenic activities on the ecosystem (US Environmental Protection Agency, 1997. Ecological Risk Assessment Guidance for Superfund: P...

In this work, the development of an integrated decision-making system for the assessment of cleaning interventions on marble architectural surfaces is presented. The suggested system resulted by the incorporation of a fuzzy logic model into GIS and its architecture includes: (a) a GIS based graphical user interface for features and attributes retrieval, management comparison, analysis and corre...

This paper evolved from the results of RADATT (RApid Damage Assessment Telematic Tool), a project funded by the European Commission, whose goal was to sensibly reduce the effects of a devastating seismic event by providing the responsible agencies a rapid and reliable damage detection and estimation of the extent and location of the suffered area. This result was accomplished by the integration...

The inclusion of error handling capabilities within geographical information systems (GIS) is seen by many as crucial to the future commercial and legal stability of the technology. This thesis describes the analysis, design, implementation and use of a GIS able to handle both geographical information (GI) and the error associated with that GI. The first stage of this process is the development...

Stevens Point Water and Sewerage Department recently began the process of creating and maintaining their utility infrastructure information in ArcInfo. With their infrastructure data now available in a GIS, the Department saw the advantage of accessing the GIS data from their field vehicles through CDMA cellular phones. This paper highlights the challenges and benefits of the ArcIMS-based wirel...

In order to optimise the quality and use of abstracted waters it is imperative to assess the risk of pollution from the catchment area upstream of the supply intake. This process can be greatly facilitated through the use of environmental spatial data and decision support software. This paper describes the development of a number of tools to support environmental risk assessment and operational...

In this study we support the strategic environmental assessment process of the Coordination Plan of the District of Naples through the selection of an indicators set to monitor and evaluate the planned actions towards a sustainable mobility in the District. This process is implemented inside a GIS and its reliability is tested by linguistic hedges modelled from fuzzy sets.

This is the ®rst of two papers that elaborate an integrated drainage network analysis system (IDNAS) for agricultural drainage management. In this paper, the system components, functions and implementation are presented. The IDNAS comprises an agricultural drainage network module, an evapotranspiration (ET) module and an event-based spatio-temporal module. The network module is designed to mode...

Soil erosion poses a serious problem for sustainable agriculture and the environment. There is a need to develop a simple and practical approach for broad area mapping of soil erosion risk that uses the uncertain but available information as input data within the constraints of reasonable cost and time. In this work, a predictive approach for conducting analytical erosion risk assessment across...
