Geographical Information Systems (GIS) are used to analyse and record the relationships and patterns which occur within spatial data. The use of GIS in environmental disciplines of the oil and gas industry aids decision making and provides supporting material and evidence for legislative objectives. Fugro Environmental work in a range of GIS projects using many faceted and highly skilled teams from various Fugro group operating companies. Data from different sources can be combined and structured to provide datasets which increase efficiency and improve visual representation through a variety of ArcGIS mapping techniques.
Environmental GIS databases allow easy retrieval, management and analysis of geographically-related archived data covering a variety of sources relevant to health, safety and environmental aspects of the oil and gas development industry. Using biotope and satellite mapping Environmental Sensitivity Indices (ESI) can be mapped along coasts. ESI mapping classifies shorelines based on their sensitivities to oil pollution. Socio-economic and environmental data can be overlaid on these maps using GIS to provide additional information relating to specific coastal sensitivities such as turtle nesting sites, mangroves or recreational areas. ESI maps are an internationally recognised tool in efficient oil spill contingency planning.
GIS mapping and GIS analysis can reduce the effort needed for surveys and improve knowledge and understanding of an area. Information is presented in a format custom made to suit the client’s data and requirements.
