Environmental impact assessment with remote sensing at Isahaya land reclamation site

摘要

Environmental impact assessment (EIA) is a sequence of procedures to evaluate a project and to make it sound in terms of environmental conservation. It plays a vital role to protect our environment from developments which inevitably give impact on surrounding environment. It is, however, not easy to carry out the EIA for big scale of projects since the EIA requires to collect various kinds of data in spatial and temporal dimensions. In this study remote sensing methodologies are investigated for monitoring environmental parameters in spatial and temporal dimensions in the environmental impact assessment. As a case-study, Isahaya land reclamation project in Kyushu, Japan was selected, and satellite remote sensing methods were investigated with LANDSAT/TM, ADEOS/AVNIR and TERRA/ASTER to produce environmental thematic maps including suspended sediment concentration and land-cover distribution in and around the project site.
