山坡地社區環境地質災害GIS查詢、展示系統建立

內政部建築研究所於民國96至98年間，執行為期三年坡地社區周緣環境地質災害判釋與風險評估計畫，成果豐碩，為了有效率的進行坡地社區環境地質災害風險分析等相關成果彙整，本研究將蒐集之各項GIS圖資整合至地理資訊系統資料庫內，並建立山坡地社區環境地質災害GIS查詢、展示系統，除呈現各單位蒐集之相關圖資及影像外，亦將風險分析與環境地質災害判釋成果納入GIS查詢系統中，便於日後使用者查詢各坡地社區的環境地質敏感區相關資訊。此外，本系統考量多元性資料整合功能，亦將各坡地社區過去的調查成果報告、災害照片、衛星影像及航空照片等資訊一併納入系統之中，提供使用者可快速瞭解各社區環境地質、區域開發狀態、災害歷史、可能發生災害位置、風險分級與優先防治區域等資訊，以供各單位進行山坡地管理時輔助決策參用。

Between 2007 and 2009, Architecture and Building Research Institute of the Ministry of the Interior carried out a program to conduct environmental-geological disasters determination and risk assessment for hillside communities. The result was very productive. In order to effectively compile the risk analysis results of environmental-geological disasters in hillside communities, this study consolidated the various collected GIS data to the geographic information system and established GIS display and inquiry systems for risk analysis of hazards in hillside communities. In addition to displaying the data and images from various units, the results of risk analysis and environmental-geological disasters determination are also incorporated into the GIS display system, making it easier for users to query information on the environmentally-geologically sensitive areas in each hillside community. Moreover, this system took the diverse data consolidation function into consideration and included information such as investigation reports, photos, satellite images, and aerial photos into the system. This provides the information that users need to quickly understand the environment-geology disasters of each community, status of regional development, historical disasters, location and range of potential disaster, risk rating, and the sensitive area to help each agency to make decisions in hillside management.
