豊島廃棄物等処理事業における処分地管理手法の高度化に関する検討

抄録

This report shows the development of a management method of Teshima waste disposal project using GPSbased 3D modeling method. Teshima waste disposal project has been conducted since 2003 as a solution of the illegal industrial waste dumping occurred in Teshima-island, Kagawa Prefecture. To prevent illegal dumping and to accumulate data of this project, we took a survey of the disposal area 4 times a year and made the 3D model of the area. By comparing the 3D model change in time course, we can show stakeholders how the project has advanced. And by surveying the area changed between the two 3D models, we can calculate the volume of disposed garbage. So, we call this system a “Co-creation system”. Therefore, we compared the cost and accuracy of GPS surveying, Light wave surveying, and Laser surveying. With this system we promoted information sharing between stakeholders.
