A conceptual framework for an integrated spatial environmental impact assessment based on GIS

摘要

This thesis develops a conceptual framework for a GIS-based integrated spatial environmental impact assessment for mining projects. In recent years, GIS has become wide spread and many specified programs and applications have beenuddeveloped. While spatial overlay is the most popular GIS analysis in EIA, a range of additional functions is available, which have not been fully utilised, including. environmental modelling and web-enabled and mobile GIS. In current EIA theory, strategic and holistic assessment strategies have gained in importance. GIS can contribute towards such strategies through integrated spatial analysis and linked database management. Also, visualisation techniques in GIS can improve communication between all stakeholders and become an essential part of the EIA process. The open cut iron-ore mine at Savage River was chosen as an example to demonstrate the benefits of GIS in EIA. In the hypothetical GIS-based EIA process, illustrative examples are given for analysis of different environmental and socioeconomicudimpacts. Implications for the existing planning system in Tasmania are discussed.
