The 3DEIA is e a key tool in promoting Continual Public Involvement (CPI), as well as providing a simple and effective method for gathering public feedback throughout the lifecycle of infrastructure projects.

The key advantage to 3D modelling lays in the ability to demonstrate proposed changes ‘visually’ to the community, giving them a better understanding of the potential impacts a project may have on their current situation, allowing them to provide Government with more valuable feedback.

While 3D modelling assists in demonstrating a proposed development to the public, it also adds value in project planning. 3D modelling allows planners to conduct a full ‘visual analysis’ that’s not possible with 2D GIS. The ability to control the height and colour of buildings, land elevations, vegetation and roadways provides a true picture of how a proposed development will look and allows planners to more accurately assess issues such as visibility and air flow activity.

NGIS have developed a number of interactive environmental visualisation tools to support EIA and environmental modelling activities.  NGIS are currently hosting the site for EPD at www.ngis.com.cn/epd/3deia/english/welcome.html
