可延伸式標記語言(Extensible Markup Language,XML)是W3C (World Wide Web Consortium)發展的結構化文件標準。OGC (OpenGIS Consortium)則以XML為基礎,制定了用於模式化、交換與儲存地理資訊的標準—地理標記語言(Geography Markup Language,GML)。 地理資料的建置,需要大量的人力與物力,因此,整合分散於各單位的資料,達到資料共享與交換的目的,成為重要的課題。人口資料是社會經濟資料的基礎,也是GIS中重要的「非空間」特性。本研究以台灣的人口資料為例,檢視XML做為人口資料格式,在資訊應用、資料交換與共享方面的效果,並嘗試與GML做初步的整合。 本研究主要分為兩部份。第一部份在於整合「戶口普查」、「戶籍登記」的人口資料分類標準,制定人口資料XML Schema。第二部份利用人口資料XML Schema產生人口資料XML文件,對人口資料XML文件實作查詢、統計、交換、格式轉換、驗證的應用,並將人口資料XML Schema、人口資料XML文件與GML做初步的整合。
Extensible Markup Language (XML) is a simple, very flexible text format proposed by World Wide Web Consortium (W3C). OpenGIS Consortium (OGC) specifies the Geography Markup Language (GML) in an XML encoding for the modeling, transport and storage of geographic information. Building complete geographic database needs efforts and resources. There is always a need to share and exchange geographic information among different organizations. Population data is the basis of social and economical research as well as the important non-spatial property of geographic features. There are two parts in the thesis. First, the population XML Schema is created by integrating the definitions of "Population and Housing Census"(戶口普查) and "Household Register"(戶籍登記). Second, the population XML documents are produced. These XML documents are surveyed in the application for querying, gathering statistics, exchnging, format transforming, validating and are integrated with GML.
