雖然近年來環保單位對空氣污染監測與控制不遺餘力，空氣品質惡化的現象已逐年趨緩。但當空氣污染緊 急事件發生時之處理過程仍彰顯污染源追蹤、污染物擴散和污染物種類等的監測依然相當棘手。而要迅速 將資訊整合、配合相關專業調度進而提升稽查管制效能、杜絕污染源維護空氣品質，將是本項新技術之應 用領域。由於監測設備中有光學雷達／光達 (LIDAR) 的加入，結合地理資訊系統 (GIS) 能快速呈現污染 源和污染物擴散之影響範圍，並以雲端技術提供相關人員快速有效之系統與資訊服務，有利於提升環保相 關單位對於空氣污染資訊之時效性和全台工業區污染物監控、空氣品質預警與災害防制等技術。

An effort has been made by EPA (Environmental Protection Administration) to prevent deterioration of air quality. However, tracking pollution source, the dispersion and types of pollution are rather difficult especially when air pollution emergencies occur. Therefore, the application of this new developing technique, combined the newly 3-D scanning LIDAR (light detection and ranging) system with GIS (geographic information system) and fast integration of information by cloud computing technique will be useful to enhance the effectiveness of inspection and to strengthen the capability of the environmental monitoring.
