  • Implementing OGC Web Map Service Client Applications Using JSP, JSTL and XMLC
    Implementing OGC Web Map Service Client Applications Using JSP, JSTL and XMLC Hao Ding , Richard Pascoe & Neville Churcher Department of Computer Science University of Canterbury. Christchurch, New Zealand Phone: +64 3 364-2362 Fax: +64 3 364-2569 Email: [email protected] , {richard, neville}@cosc.canterbury.ac.nz Presented at SIRC 2002 – The 14th Annual Colloquium of the Spatial Information Research Centre University of Otago, Dunedin, New Zealand th December 3-5 2002 ABSTRACT Java technologies are widely used in web application development. In this paper are described three approaches to developing Java-based web applications and our experiences with applying each to the development of client that interact with servers implementing the OGC (Open GIS Consortium) Web Map Service (WMS) specification. Also described is the installation and configuration of open source software that implements the WMS specification. The paper is concluded with some preliminary insights into when one of the three approaches to WMS client implementation is more suited to another. Keywords and phrases: WMS, JSP, JSTL, XMLC, map layer, web map server 1.0 INTRODUCTION Of the many technologies, such as Common Gateway Interface (CGI), Active Server Pages (ASP), JavaServer Pages (JSP), that are used to develop web applications, three are of particular interest to the research presented here. These three technologies or approaches to developing clients that utilise web services are JavaServer Pages (JSP), JSP with the use of tags from the JSP Standard Tag Library (JSTL), and the eXtensible Markup Language Compiler (XMLC). JSP is a more convenient way to write Java servlets, and allows the insertion of Java code directly into static HTML (Hypertext Markup Language) pages.

The work has been carried out by ESYS plc and the Dept. Geomatic Engineering at University College London under funding by the BNSC International Co-operation Programme 2. The project is in support of the activities of the CEOS Working Group on Information Systems and Services (WGISS). Following trial implementations (using software from Cadcorp, Ionic and Deegree) the final implementation uses the University of Minnesota Web Map Server (UMMS) with a client developed from Ionic’s RedSpider software. Some extensions to the functionality in Ionic’s client are explained. This document provides guidelines to assist other data provider organisations set up similar OGC compliant servers and serve, over the Internet, similar continental-scale full-resolution SRTM and Landsat data.
