Hướng tới GIS chế đối với Biển Iroise (Pháp) Theo như các vùng ven biển có liên quan, nhiều thách thức phải đối mặt với cộng đồng khoa học và các nhà hoạch định chính sách, lập kế hoạch và quản lý biện minh cho nhận con nuôi của một cách tiếp cận transdisciplinary dựa trên sinh học-hóa chất, yếu tố địa vật lý và socioeconomical (Burbridge và Humphrey, năm 1999). GIS được thành lập dựa trên hệ thống máy tính để lưu trữ, thu hồi, phân tích, mô hình và hình dung lượng lớn các dữ liệu không gian. | CHAPTER ELEVEN Towards an Institutional GIS for the Iroise Sea France Eranẹoise Gourmelon and Iwan Le Berre INTRODUCTION As far as coastal zones are concerned many challenges faced by the scientific community and policy makers planners and managers justify adoption of a transdisciplinary approach based on bio-chemical geophysical and socioeconomical factors Burbridge and Humphrey 1999 . GIS are well-established computer-based systems for storing retrieving analysing modelling and visualising the vast amounts of spatial data that may be collected by several providers Fabbri 1998 . Nevertheless the implementation of a coastal database is a complex process which requires institutional support to guarantee the multidisciplinary approach the sustainability of the project in terms of raising funds and human resources and to promote relationships with other institutions working on the same area De Sède and Thiérault 1996 . The major pollution caused by the Erika disaster coupled with the catastrophic storms which reached the Atlantic coastal zone at the end of 1999 has led the French authorities to propose creation of a national coastal GIS. The implementation of such a project is complex witnessed by the lack of any decision about which reference geographical data for the coastal zone to adopt Allain et al. 2000 . In fact coastal data are scattered among many organisations. They are produced for lots of purposes and therefore are available at various scales typologies and formats. In spite of these difficult conditions there are a number of smaller independent GIS projects at work on the French coastal zone ENR OELM 2000 Guillaumont and Durand 2000 . This contribution describes the GIS implemented by Géosystèmes laboratory CNRS European Institute for Marine Studies on the coastal zone of Finistère western Brittany see Figure during the last ten years. In the beginning the GIS was conceived as a support tool for monitoring and managing the Biosphere Reserve of .
