EIA(Environmental Impact Assessment)
“The Environmental Impact Assessment (EIA) is designed to review, predict, and assess
the potential environmental impacts of a project before its plan is finalized in order to
come up with measures to prevent or minimize any possible adverse effects that the
project could have on the environment.”
<Source: Korea Environment Corporation, https://www.keco.or.kr/en/core/contentsid/3016/index.do>
“Environmental Impact Assessment (EIA) purpose is to ensure that the environmental
and social effects of proposals are understood prior to decisions being taken and to aid
public participation in decision-making.”

EIA Key Stages

Huge and burdensome

Stuffed in documents – Non interactive

I can see the assessments and predictions in an
interactive way?
I can change the development plan by myself and want
to see the results in real-time?
We can interact with other stakeholders through one
single EIA platform?
We can visualize BIM and 3D GIS data on a web
browser?

• Current EIA statements are quite paper document oriented.
• Current EIA statements are hard to navigate, read, and understand with full of
jargons, technical terms, and scientific numbers, which make public inaccessible to
the real meaning of the statements.
• EIAs are falling behind other industries harnessing digital technology to drive
productivity.
• This research is an attempt to increase transparency, accessibility, trust,
interactions among stakeholders around EIA processes.
• It is expected to give a new tool to stakeholders for understanding EIA processes
by developing new ways of EIA data visualization.
• Still long way to go.
