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. -

I have performed this research part-time at the section GIS Technology of TU Delft in cooperation with the Kadaster (the Dutch Cadastre), in order to get the Master of Science degree in Geodetic Engineering. Typing the last words for this thesis, I have been realizing more than ever that this thesis marks the end of my time as a student at the TU Delft. However, I also realize that I have been working to this point with joy. Many people are “responsible” for this, but I’d like to mention the people who have contributed most. First of all, there are of course people who were directly involved in the research project. Peter van Oosterom had many critical notes and - maybe even more important - the ideas born out of his enthusiasm improved the entire research. -

Image Matters LLC [email protected] [email protected] ABSTRACT A precursor paper (also available as an OGC White Paper) provides a high-level overview of and architecture for the Open Geospatial Consortium (OGC) standards activities that focus on sensors, sensor networks, and a concept called the “Sensor Web”. This OGC focus area is known as Sensor Web Enablement (SWE). For readers interested in greater technical and architecture details, please download and read the OGC SWE Architecture Discussion Paper titled “The OGC Sensor Web Enablement Architecture” (OGC document 06-021r1). Keywords Sensor, OGC, “Sensor Web Enablement”, “sensor web”, transducer, geospatial, “web service”, SOA, “service oriented architecture”, imaging. INTRODUCTION A sensor network is a computer accessible network of many, spatially distributed devices using sensors to monitor conditions at different locations, such as temperature, sound, vibration, pressure, motion or pollutants1. A Sensor Web refers to web accessible sensor networks and archived sensor data that can be discovered and accessed using standard protocols and application program interfaces (APIs).

Integrating the Ogc Sensor Web Enablement Framework Into the Ogc Catalogue
INTEGRATING THE OGC SENSOR WEB ENABLEMENT FRAMEWORK INTO THE OGC CATALOGUE S.Jirka a, *, D. Nüst a, J. Schulte a, F. Houbie b a Westfälische Wilhelms-Universität Münster, Institut für Geoinformatik, Weseler Straße 253, 48151 Münster, Germany - (jirka, daniel.nuest, janschulte)@uni-muenster.de b ERDAS SA, Quai Timmermans 14/01, 4000 Liège, Belgium - [email protected] KEY WORDS: Internet/Web, Interoperability, Metadata, Sensor, Software, Standards ABSTRACT: The Sensor Web Enablement (SWE) architecture of the Open Geospatial Consortium (OGC) has reached a broad acceptance. However, although the core specifications reached a mature state, the integration of a cataloguing service for sensors has not yet been achieved. Previous work focused on registries that address the specifics of dynamic sensor networks, on mechanisms for handling the semantics of phenomena and on metadata models based on the Sensor Model Language (SensorML). This work describes how existing elements supporting sensor discovery can be coupled with the already well established OGC Catalogue Service (CSW). The approach presented in this work relies on a SensorML profile specifying metadata necessary and sufficient for sensor discovery. SensorML documents that conform to the profile are automatically harvested from SWE services by a lower level registry and are subsequently transformed into an information model supported by the CSW. Finally the metadata is pushed into CSW instances and becomes available through the CSW interface. In summary, this work presents for the first time a working example how resources provided through SWE services can automatically be published through common OGC Catalogue Service instances. We expect that the presented approach is an important step in order to achieve a full integration of SWE components into spatial data infrastructures and to offer SWE services to a broader audience. -
Approach to Facilitating Geospatial Data and Metadata Publication Using a Standard Geoservice
International Journal of Geo-Information Article Approach to Facilitating Geospatial Data and Metadata Publication Using a Standard Geoservice Sergio Trilles *, Laura Díaz and Joaquín Huerta Institute of New Imaging Technologies, Universitat Jaume I, Castellón de la Plana 12071, Spain; [email protected] (L.D.); [email protected] (J.H.) * Correspondence: [email protected] Academic Editor: Wolfgang Kainz Received: 10 March 2017; Accepted: 16 April 2017; Published: 25 April 2017 Abstract: Nowadays, the existence of metadata is one of the most important aspects of effective discovery of geospatial data published in Spatial Data Infrastructures (SDIs). However, due to lack of efficient mechanisms integrated in the data workflow, to assist users in metadata generation, a lot of low quality and outdated metadata are stored in the catalogues. This paper presents a mechanism for generating and publishing metadata through a publication service. This mechanism is provided as a web service implemented with a standard interface called a web processing service, which improves interoperability between other SDI components. This work extends previous research, in which a publication service has been designed in the framework of the European Directive Infrastructure for Spatial Information in Europe (INSPIRE) as a solution to assist users in automatically publishing geospatial data and metadata in order to improve, among other aspects, SDI maintenance and usability. Also, this work adds more extra features in order to support more geospatial formats, such as sensor data. Keywords: metadata; geospatial data; geoservice; standard; spatial data infrastructures (SDI); Infrastructure for Spatial Information in Europe (INSPIRE) 1. Introduction The current trend is to deploy and organize Geospatial Information (GI) into what is known as Spatial Data Infrastructures (SDIs) [1]. -

M.E. de Vries Dr.ir. B.M. Meijers Co-reader: Dr. Dipl.-Ing. S. Zlatanova ABSTRACTDevelopments such as smart cities, the Internet of Things (IoT) and the Infras- tructure for Spatial Information in Europe (INSPIRE) are causing a growing amount of observation data to be produced. The Open Geospatial Con- sortium (OGC) has developed Sensor Web Enablement (SWE) standards for modelling and publishing this data online. However, their use is currently limited to geo information specialists, who have knowledge about which data services are available and how to access them. With the use of the semantic web, online processes can automatically find and understand ob- servation metadata. This opens up the SWE services to a large user audience. -
