Design And Implementation Of Archaeological Site Information System Based On WebGIS

By digital implementation Geographical Information System (GIS) reflects the ? spatial data and property data of the earth on which people depend to survive. GIS supports spatial data and property data's input, output, storage, display, inquiry, general analysis and assistant decision-making. WebGIS is a technology based on the Internet and GIS. WebGIS is more excellent than general MIS in the Archaeological Site Information System (ASIS) and it provides distributive management and multimedia query and so on.This dissertation discussed the WebGIS implement technique based on the Microsoft.Net. In this paper an Archaeological Site Information System based on WebGIS is designed and implemented according to the demand of the archaeological study and cultural relic protection. The paper mainly includes:1) Most of common functions of WebGIS such as ZoomIn, ZoomOut, Pan and so on are implemented in the Microsoft.Net. By putting forward a series of methods, the paper can reduce the postback times of the client of WebGIS, and raise the efficiency of the client.2) A kind of Object-Relation Mapping method based on three layers framework is designed, which is constituted by a series base classes. User can rapidly access the database through it.3) A kind of open description method of attribute based on XML is designed. It is easy to add or remove attribute from attribute set because all attributes are described with a XML document. Furthermore, the XML document contains not only the attribute's value, but also some additional information such as attribute's type. As a result, the appearance of the attribute on webs varies from each other. This method has an advantage over the traditional method because of the characteristic of XML.
