地層下陷相關決策資訊包含各鄉鎮水井清查、水準高程測量、GPS監測、地陷井監測...等，因往年相關資訊並無資訊系統及資料庫進行管理及展示，本署爰於100年度辦理「地層下陷資訊整合服務系統規劃建置」計畫，建置資料庫及開發地層下陷資訊整合系統。此外，為強化測站及監測資料管理目標，以及提高GIS圖層套疊彈性，另於104年辦理「地層下陷資訊整合服務系統維護及管理」。 本計畫兩項系統並之測站及監測資料管理功能已逐步完成，並提供使用者綜合展示檢、監測資訊，以初步分析地層下陷成因。為使本系統更臻精進，以及輔助本署辦理地層下陷相關業務，後續將朝加值應用分析進行開發，例如即時產出GPS測站監測資訊下陷等值圖、開發行動版介面、地下水與下陷關係視覺化...等，並改善系統圖表可再編輯功能，俾利使用者可彈性運用製作簡報。

In order to control land subsidence and the causes, to integrate the monitoring information of hydrology, geology and meteorology in land subsidence area is necessary. The monitoring data include GPS, in-depth layer subsidence measurement, leveling measurement, investigation for pumping well, precipitation, ground water pressure, lithological log, and so on. The Water Resources Agency, Ministry of Economic Affairs integrated the relevant information of land subsidence to establish a database, and has finished both single and online information platforms, named “Land Subsidence Integrated Information Service System” in 2011. The functions of these two systems includes displaying, analyzing and inquiring most of the land subsidence information, which can also produce required images and forms immediately. This project plans to keep abreast of the latest data, as well as expand the function for “Land Subsidence Integrated Information Service System” with the purpose of updating the database of the system by a user-friendly interface, inspecting and modifying ability of the account and information for system administrator, and showing the analyzed image of land subsidence comprehensively. The main working projects shown as below : 1. Establish “Integration System of Land Subsidence Monitoring Information--- Back-End Management Platform”. 2. Revision the original system and expand the functions of the system. 3. Exchange the monitoring data with other agencies. Firstly, establish the “Integration System of Land Subsidence Monitoring Information--- Back-End Management Platform.” It includes four managing functions : system account management, monitoring stations and levelling site management, monitoring equipment management. The function allows administrator to set up and modify the user’s account and access permission, to inspect login record, to bulk import and export the monitoring information from the platform, and to modify the basic information of station and equipment. Secondly, to change the base map of “Land Subsidence Integrated Information Service System” from Google map to Arc GIS, the one used in Geographic Information Center, to show the information of monitoring stations and leveling sites. Expand the function means to add on the analysis results of land subsidence causes in synthesis chart. And then customize the result of monitoring and analysis by drafting them on one chart. Thirdly, interface the monitoring information from other agencies aims to promote the accuracy of the situation of land subsidence. By storing those data into existing database and normalizing the column on the form, we can increase the amount of GPS monitoring station and create better analysis results. After renewing the “Land Subsidence Integrated Information Service System”, system administrator can update and modify the monitoring and other information by using simple and intuitional platform. In addition, they can master the latest information and analysis results. Last but not the least, since the authority concerned can compare different causes in synthesis chart and observe the trend with plentiful GIS layers, they can greatly improve the analysis for land subsidence, as well as the capacity to take decisions.
