105年度多尺度遙測影像分析與展示平台擴充維護
105年度多尺度遙測影像分析與展示平台擴充維護
由於地球暖化，導致劇烈天氣發生的程度與頻率加劇，並造成人民與國家社會嚴重損失。政府因應天然災害之對策已從傳統的救災工作改以智慧防災為工作重點。近年來5S空間資訊(5 Spatial Information)已經成為防災及各個領域的資訊取得與分析研判工具。5S空間資訊包括了地理資訊系統(GIS, Geographic Information System)、遙感探測(RS, Remote Sensing)、全球定位系統(GPS, Global Positioning System)、空間決策支援系統(DSS, Decissiion Support System)以及專家(ES, Expert System)。本計畫所建置與持續擴充維護之「防災空間資訊系統」，成功整合了水文、氣象、警戒、災情、與各類重要的空間圖資，並讓使用者可容易地透過網際網路平台，設定不同時空條件，快速搜尋與呈現瞬息萬變的水利防災應變資訊。同時也整合GIS, RS, GPS技術，並朝向DSS的功能改進，已能便捷地將各種資料進行套疊與交叉比對分析，支援水利防災應變決策工作。
本計畫以署內同仁為主要使用者，蒐集多尺度災害遙測圖資並協助發布與分析，強化水利署對於空間資訊的掌握能力，並以防災空間資訊系統為整合資訊平台，協助水利署防災值班作業順暢。本系統提供多項特色功能包括雙向的列表選單操控與顯示，過去與未來時間、空間整合的顯示，三維立體展示界面，影片導覽功能，即時與歷史情資的圖層重疊比較，單雙視窗畫面同步顯示與比較，以表查詢圖及圖配合表雙向功能等，以災害為核心的資訊展示輔助決策系統。署內所屬各個單位擁有自己的圖資運作空間及權限。本計畫完成四個工作項目：(1)擴充並維護防災空間資訊系統(2)配合水利署相關值勤作業(3)教育訓練及配合水利署參與防災推廣活動(4)遙測影像蒐集與判釋。
今年新增簡易操作的快速顯示界面、逐時歷史災害事件圖資、自有照片上傳事件降雨排名等多項新功能，提供水利署各級單位在共通平台上擷取不同層級所需的防救災輔助決策資訊。以5S技術建立多尺度遙測資訊整合系統，提供防災應變上之模擬演練、防災資源佈署配置資訊、協助水利署於災前預警、災中快速應變，以及災後空間資訊的快速掌握以迅速瞭解災情並儘速復建完成防汛工作。

2016 Multi-Stage Remote Sensing Data Analysis and Disaster Display Platform Expansion and Maintenance
Abstract
Global warming is already having significant and costly effects on our communities, our health, and our climate. These impacts will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet. The consequence is now accelerating the rate of sea level rise, increasing flooding risks to low-lying communities and high-risk coastal properties whose development has been encouraged by today's flood insurance system. 5S(5 Spatial) information is been utilized in this project.
This system was designed for users of Water Resources Agency(WRA) which is the Disaster Prevention and Emergency Response Geospatial Information System (DPERGIS) that was developed, expanded and maintained by this project, has successfully integrated hydrology, meteorology, warnings, disasters and all kinds of important GIS data. It is very convenient for users to access DPERGIS via internet and set up various criteria of space and time to quickly search and display those GIS data related to water resource disaster prevention and emergency response. Meanwhile, all GIS data can be easily overlaid with each other by DPERGIS, which enables the users to make a cross comparison and analysis, as well as supporting the work of disaster emergency response and decision making in water resource.
DPERGIS involed GIS(Geographic Information System)、RS(Remote Sensing)、GPS(Global Positioning System) which includes multi-scale 3D animation、table list and bottom selction、overlapping realtime and historical data in images and vectors format to support necessary information to WRA’s staff to make decision for disaster events as possible. Devided subdata set could be manupulated by each local river agency and dam agency for their interested targets. Four tasks are implemented in this project as (1)Extend and maintain system functions and data sets. (2) Join WRA disaster contingency group. (3) Making system training and attend WRA annual conference. (4) Remote Sensing Data collection and analysis.
The advantage of this system are providing multiscale data of disaster information in time and spatial domain under 5S skill, let staff of WRA more easy to make right decision in the right time for decreasing severe disaster occurred and quicky make strategy of disaster recovery. This project indeed provide a powerful platform that is able to support the work of disaster emergency response and decision making in water resource.
