It is a time-consuming and labor-intensive task to perform ground investigation when a large-scale pollution happens. In order to locate the spread area of the pollution, this study integrates spatial data collection and processing technologies to help monitor the polluted areas. There are five objectives: 1.use remote sensing technology to collect the polluted evidence 2.design unmanned boat and balloon to enhance monitoring capabilities 3.improve the functions of the digital investigation system 4.enhance the content (3D) of the environmental database 5.hold training courses
