XML-based model libraries application in Geographic Information System

Abstract

In recent years, with the development of technology, the potential and application value of GIS (Geography Information System) has been shown in various fields. GIS performs well in data processing and graphic display but still has some shortcomings in some high-abstract-level areas like model library. In this paper we presented a model library by XML (Extensible Markup Language), and described its detailed description and realization. This model library has favorable encapsulation, expansibility and openness, perfectly meeting the demand of Geography System.
