Web Coverage Processing Service Specification Version 0.0.1

Trimita Chakma, Dr. Peter Baumann · 2014

Geospatial data describe natural and social phenomena or events on Earth. Because of their importance to socio-economic activities, huge volumes of geospatial data have been collected by both public and private sectors. Due to their multi-disciplinary nature, geospatial data products may differ in spatial / temporal extent and resolution, origination, format, name convention, and map projection. In order for geospatial data to be useful, the data have to be processed to extract information based on requirements of individual applications. A typical Earth science application requires access to and manipulation of data and information from multiple sources provided by multiple data and information systems. In order to facilitate the interoperability, the geospatial community has developed a set of technologies, standards, and interface protocols. [1] OGC is an international organization promoting the interoperability and sharing of geospatial resources and services in the distributed environment through the development of consensusbased implementation specifications [2]. The recently developed OGC web-services specifications allow seamless access to geospatial data in a distributed environment, regardless the format, projection, resolution, and the archival location [3]. One of the fundamental ones

Used parts of other documentsThis document uses parts of document [OGC 06-121r3].To reduce the need to refer to that document, this document copies some of those parts with small modifications.To indicate those parts to readers of this document, the largely copied parts are shown with a light grey background (15%). Platform-neutral and platform-specific specificationsAs specified in Subclause 5.4 of OWS Common [OGC 06-121r3], this document includes both platform-neutral and platform-specific specifications.EXAMPLES 1 Platform-neutral specifications are contained in Clause 6.EXAMPLES 2 Platform-specific specifications for XML encoding are contained in Clause 7.

IMPLEMENTATION WAYS FOR WEB COVERAGE SERVICE STANDARD

Evgeny Panidi, Anton Terekhov, Mark Mukhamedzyanov · 2016

This study is dedicated to design and implementation of two software prototypes, which are facilitate fast and simple Web publication of the raster coverages without specialized dedicated Web infrastructure. First prototype is implemented in Python programming language as a server-side Common Gateway Interface (CGI) application. The second is implemented as a module for Node.js platform, which is very popular for development of the multipurpose Web applications. Both solutions can be deployed using virtual shared hosting. This feature expands the opportunities of geospatial data publication on the Web for small-and medium-scale projects.

Web Service Testing Method Based on Fault-coverage

Wenli Dong, Hang Yu · 2006

The aim of web service verification is how well the web service conforms to the WSDL specification and it is the key of web service popular adoption at present. In web service testing, the adequacy of test is the essence to verify if the software satisfies WSDL specification with the increasing complexity and applications of web service. This paper presents a systematic approach for web service testing based on fault-coverage which is intended to be used for service testing automation. In this method, HPNs representing operations are produced from WSDL specification after parsing process. A graph transforming from the HPN representing a web service is used to generate the adapted UIO sequence, then test sequence based on the adapted UIO sequence is given to acquire high fault coverage. Constraints-based test data generation for service testing getting sufficient test data to kill mutant program is presented in this paper. Constrains are departed to two kinds: user-defined and policy based on the syntactic and semantic analysis for WSDL specification. At last, we applied a test script language based on XML to effectively describe the test sequence. The test sequence and constrains for test data are expressed by this language. The test scenario is built on this formal language. The prototype system based on above method automating the web service test is developed in our lab.

OGC Web Coverage Service Interface Standard - Interpolation Extension

Peter Martin Jacobs, Jinsongdi Yu · 2014

This OGC standard specifies parameters to the OGC Web Coverage Service (WCS) GetCoverage request which give control over interpolation of a coverage during its server-side processing.This allows the client (user) to control and specify the interpolation mechanism to be applied to a coverage during server processing.This WCS Interpolation extension relies on WCS Core [OGC 09-110r4] and the GML Application Schema for Coverages .

Towards a web coverage service for efficient multidimensional information retrieval

Deshmukh, A. · Fraunhofer-Publica (Fraunhofer-Gesellschaft) · 2022

Historisch sind Business Intelligence (BI) und Geografische Informationssysteme (GIS) getrennten Entwicklungs- und Implementierungspfaden gefolgt. Kundenanfragen nach einem kompletten betrieblichen Bild, und der Bedarf nach mehr pro-aktivität hat zu einer synergistischen Macht geführt, die mit der Integration von BI und GIS ausgenutzt werden kann. Eine integrierte Geographic Business Intelligence Solution (GBIS), ein von (ESRI, 2005) geprägter Begriff, ermöglicht Benutzern, räumliche Information zu visualisieren und verwalten. Entscheidungsträger können mit standortbezogener Intelligenz auf verschiedenen Ebenen bewerten, planen und Dienste leisten, Information präsentieren und ad hoc Geschäftsfragen beantworten. Eine integrierte Lösung verbessert die Entscheidungsfindung und Ansprechbarkeit, indem sie die Eignung von GIS auf eine breitere Reihe von Geschäftslösungen ausdehnt. Die Suche nach einer GBIS-Lösung führte zur Einführung einer neuen Unterkategorie von raumbezogene Entscheidungfähige Lösungen: Spatial Online Analytical Processing (SOLAP) oder Spatial OLAP. Diese Studie trägt zur Entwicklung der SOLAP Thematik bei, indem sie eine interoperable, web-basierte, offene und erweiterbare prototypische Lösung mit den Analyse-Fähigkeiten der beiden Technologien präsentiert. Der Prototyp beruht auf dem Web Coverage Service (WCS) nach Definition des Open Geospatial Konsortium (OGC), kombiniert mit einen OLAP Server. Der Autor hat eine vorhandene WCS Implementierung erweitert, um noch nicht vorhandene Coverage-Typen und die Fähigkeit mehrdimensionale Daten von einem OLAP Server anzufordern und zu verarbeiten. Die Besonderheit dieser Lösung besteht darin, beide Aspekte auf der Grundlage einer einzigen Abfragemechanismus abzufragen. Szenarien, konzipiert für Datensätze der Deutsche Presse Agentur (dpa) bilden die Grundlage zur Evaluation der erweiterten Lösung. Die Ergebnisse sind positiv und bieten eine solide Basis für die weitere Forschungsarbeit in diesem mehrdisziplinarischen Gebiet.

Testing OGC Web Feature and Coverage Service performance: Towards efficient delivery of geospatial data

Grégory Giuliani, Alain Dubois, Pierre Lacroix · Journal of Spatial Information Science · 2013

OGC Web Feature Service (WFS) and Web Coverage Service (WCS) specifications allow interoperable access to distributed geospatial data made available through spatial data infrastructures (SDIs). To ensure that a service is sufficiently responsive to fulfill users’ expectations and requirements, performance of services must be measured and monitored to track latencies, bottlenecks, and errors that may negatively influence its over- all quality. Despite the importance of data retrieval and access, little research has been published on this topic and mostly concentrates on the usability of services when integrating distributed data sources. Considering these issues, this paper extends and validates the FOSS4G approach to measure the server-side performance of different WFS and WCS services provided by various software implementations; and provides guidance to data providers looking to improve the quality of their services. Our results show that performance of tested implementations is generally satisfactory and memory tuning/data and storage optimization are essential to handle increased efficiency and reliability of services.
