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. -

Integrated CEOS European Data Server (ICEDS): Guidelines for Implementing an OGC Web Coverage & Web Map Server to Serve Global-Scale, Full-Resolution SRTM and Landsat Data 1 ICEDS: Guidelines for Implementing an OGC Web Coverage & Web Map Server Reference: ESYS-RPT-2005487-02, Issue: 30 March 2006, Version 3. 2 ICEDS: Guidelines for Implementing an OGC Web Coverage & Web Map Server Reference: ESYS-RPT-2005487-02, Issue: 30 March 2006, Version 3. 1 Executive Summary The Integrated CEOS European Data Server (ICEDS) provides on-line access to a global SRTM Digital Elevation Model (DEM) together with Landsat satellite imagery for Africa and Europe and other information layers; all made available through Open Geospatial Consortium (OGC) compliant Web Map Servers (WMS) and Web Coverage Servers (WCS). 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. -

This work presents a panorama of GIS integration in Spatial Statis- tics environments. It highlights the current needs of communities considering such integration. Spatial Statistics is treated in a context focused on the use of computational tools. A review of types of integration is accomplished and a new approach is proposed integrating the statistical software R and the GIS library TerraLib. 1. Introduction Software technology is constantly evolving. Computers are becoming faster, and software projects must follow the availability of resources. This scenario favors greater complexity of software projects allowing multidisciplinary programs to combine research in several knowledge areas, like medicine, agronomy and civil engineering, among others. Geographic Information Systems (GIS) are an example of a multidisciplinary soft- ware. GIS comprise knowledge in areas such as cartography, databases and software en- gineering, among others. They are capable to manipulate several complex georeferenced data structures. In practice, statistical analysis are often necessary to extract useful infor- mation from the available data. For instance, methods of spatial analysis are particularly relevant to GIS which, in general, have limited capability to perform such analysis. -

This paper discusses the use of “design patterns” in the conception and implementation of an open source GIS library called TerraLib. The work indicates how some well-known design patterns (such as Singleton, Composite and Factory) can be effectively used in the development of GIS applications. Keywords. GIS, software engineering, design patterns, spatial information engineering. 1 IntroductionIntroduction Important books dealing with patterns include Gamma et This work discusses the use of the concepts of “Design al (1995), Buschmann et al (1996) and Vlissides (1998). Patterns” in the context of the development of GIS GIS software development has much to benefit from systems. The authors argue that these ideas are well the use of design patterns. To begin with, the GIS suited to capture the complexity of the components of a community lacks open source software tools that would GIS and that software developers in the spatial allow research results and academic prototypes to be information engineering area can benefit substantially by widely shared. Since GIS is an applied science area, using patterns in their development. academic ideas need to be experienced and tested in real- A design pattern can be defined as a common solution life applications.
