Abstract

In this paper, we propose a Web Service framework for four kinds of geo-spatial services of GIS, SIIS, ITS, and GNSS. First, we examine what requirements are needed when designing the framework for various kinds of geo-spatial services. Then, we show how the framework can contribute to efficient geo-spatial services on both wired and wireless environment. Main issues in a design of the framework are to define interoperable interfaces, to define standardized metadata, and to design efficient geo-spatial server for various kinds of geo-spatial services. The framework fundamentally adopts international standards such as WMS, WFS, WCS, and WRS announced by OGC. The adoption satisfies the interoperability, extensibility, and standardization of the framework. Especially, we focus on a design of main memory-based GIS server(MM server). The MM server can efficiently serve huge volume of GML documents via Web Service. And experimental results show the effectiveness of the framework and MM server.
