[[alternative]]Geographic Information Sharing and Exchange Using XML: A Case of Population Data

[[abstract]]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.
