This report shows the development of 3D modeling method of Teshima waste disposal project using GPS. 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 measured the disposal area 4 times a year and made the 3D model of the area. We call this system a "Co-creation system". By comparing the 3D model change in time course, we can show stakeholders how the project has advanced.. And by measuring the area changed between the two 3D models, we can calculate the amount of disposed garbage. With this system we promoted information sharing between stakeholders.
