Over the past decades, Taiwan has gone through the transformation from agriculture basis to industrialized society. Pollution and vandalism beyond the growing economy have drawn public’s attention to the importance of environmentally friendly. The public pollution and the damages it had brought to the environment have led to some critical issues nowadays for the government to keep an eye on. Policies and regulations have been made and announced by the official authority accordingly. The Taiwanese government has promoted the environmental protection technology over past years to prevent the occurrence of pollution and to suspend such cases for happening. Nonetheless, sudden major public pollution still appears from time to time and causes damages to the public society. This project aims at applying satellite imagery from FORMOSAT-2 and SPOT-5, as well as images from Unmanned Aerial System (UAS) and LiDAR to monitor public pollution. The goals of this project is to plan and build applications on remote sensing technology for the benefit of environmental investigation. The imagery data can also be used as proofs for public polluted investigations and references to clarify the accountability on the damages. In addition, the data can also assist the damage assessment.
