Project objectives
This project, ongoing since 2000, involves the development of a 3D GIS system to prevent landslides and control erosion. Landslide GIS stores and manages 3D surface and sub-surface data, facilitating landslide analysis, simulation of sliding movements, and arrangement of landslide prevention works.

Fast facts

  • Database management records of landslide prevention and forest conservation projects are used in the modeling process. 
  • The system provides 3D analysis of hydrogeological structure and prevention works of a landslide area
  • Modeling of land mass movement during a landslide and landslide movement simulation are visually depicted in 3D.

Bentley products used

  • MicroStation V8
  • GEOPAK Site

In the field of mountain hazard prevention, one cannot overstate the role of geographic information systems (GIS). These systems have been used to present information on landslide structure and the effects of prevention works to the
public, manage records of mountain hazard prevention works, and help develop emergency warning systems.

The Landslide GIS being developed and managed by the Japan Conservation Engineers Co. is at the heart of a project in the landslide-prone areas of the Akita, Yamagata, and Kanagawa prefectures in Japan. The system lets engineers better manage, evaluate, and present to clients and the public projects designed to prevent landslides. The system does this by enabling engineers to:

  • Store and manage 3D surface and sub-surface data
  • Perform 3D analysis of the hydrogeological structures and landslide prevention projects in landslide areas
  • Create a 3D simulation of landslide movements
