Establishment of spatial information application system for advanced environmental impact assessment (Ⅱ)
Ⅰ. Introduction
o Research background and purpose
An environmental impact assessment (EIA) is basically the process of reviewing the impact of individual environmental media caused by development projects and comprehensively evaluating the impact of other associated media.
Spatial data utilized in EIA have several meanings.
- The outer boundary of project sites as the overall spatial range of projects
- The locations of measured environmental media: targets of EIA
- Spatial expression of correlations between the impacts of individual media and other media
This study aims to suggest measures to establish a spatial data platform as a way to efficiently utilize spatial data across the overall process of the EIA system through the following discussions.
- The scope and content of spatial data utilized in EIA vary.
- The current EIA system promotes the utilization of spatial data.
- The Environmental Impact Assessment Support System (EIASS), a data system for EIA, provides a limited amount of spatial data based on original data.

o Research scope
As the utilization of spatial data in the entire process of EIA has increased, this study was conducted as basic research to convert the current EIA system into a spatial data-based platform.
In the first year, an inventory of various credible spatial data was established and coordinates and attribute tables were standardized in order to expand the utilization of spatial data across the entire process of EIA. In the second year, a basic plan for establishing a spatial data-based platform for EIA will be established based on the
