摘要

近年來台灣地區屢遭颱風、地震、豪大雨所引發洪水、山崩、土石流等天然災害創傷，嚴重威脅人民生命財產，引起政府對於國土復育與國土規劃之高度重視與重新思考。在辦理國土規畫、國土復育與災害防救作業過程中，基礎資料的輔助極其重要，其中國土測繪資料包括控制測量資料、數值地籍圖、數值地形圖、GPS連續觀測站、甚至航空照片、衛星影像等，更是不可缺少的重點參考資訊。然過去測繪事權分散，分由中央、地方政府或各目的事業機關辦理，無法提供對於前述資料需求殷切之各單位在短時間內搜尋、取得資料之管道，更遑論擴大服務民間業者與一般大眾。本文重點在說明台灣內政部土地測量局如何運用資料倉儲、空間資料庫、地理資訊系統、網路服務及開放式GIS等技術，推動測繪資料標準化並建立國土測繪資訊整合流通系統，達到單一網路服務窗口快速服務各界需求、資訊透明公開，實現流通共享之目標。

Over the years, natural disasters such as floods, landslips, mudflows, and landslides caused by typhoons, earthquakes and torrential rains have caused serious destruction in several parts of Taiwan. Since such disasters are a serious threat to both human-life and property, the authorities have adopted a renewed approach and are viewing national territory restoration and land use plan seriously.
Mapping data (including all measuring and controlling data, digital cadastral data, DEM, GPS continuous measuring station, aerial photo and satellite images, etc.) forms the fundamental data source for land use planning and disaster prevention or disaster rescue plan. Such data plays an important role in the restoration procedure and national land surveying processes. However, the data remains scattered with different data producers and data administration is done by diverse government agencies. In the absence of a comprehensive and structured planning schema, data management and operations such as data query and search become cumbersome processes. Also, tracing the correct department from where appropriate data can be obtained becomes a tedious process and thus results in unnecessary delay when the data is required imminently.
For this reason, this paper focuses on the application of the data warehousing technology within the Land Survey Bureau (Ministry of the Interior in Taiwan) for spatial data sharing, providing web and open GIS service, standardizing different source's spatial data format. Furthermore, the paper also discusses the goals of information disclosure by the government, data circulation, and sharing via one-stop service.
