“…For example, MapServer's web map service (WMS) has been measured and optimized [10], COSMC (Czech Office for Surveying, Mapping and Cadastre) and CENIA (Czech Environmental Information Agency) WMSs have been tested for availability and performance [9], and [20] has evaluated WMS servers and proposed a set of principles for the design of a high-performance WMS client. Moreover, a WMS performance shootout has been presented annually since 2007 at the FOSS4G (Free and Open Source Software for GIS) conference, which provides a standardized procedure for Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.…”

Recently, sensor webs have been increasingly used to monitor and sense a multitude of observations for various applications, from simple phenomena, such as air pollution measurements, to complex events, for instance perimeter security, or effluent tracking. Therefore, the performance of sensor data delivery mechanisms is becoming more and more important to ensure that services dependent upon sensor web technology perform satisfactorily. In the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) framework, Sensor Observation Service (SOS) is a standard web service interface responsible for requesting, filtering, and retrieving sensor observations. In this paper, we present initial results from a quantitative analysis of SOS servers' performance. To do this, we measured the response time and transferred data volume, the response size, of three SOS servers -52North, MapServer, and Deegree -based on different test scenarios. The results are illustrated and discussed. Our findings can be helpful: (i) to understand how different parameters affect the SOS servers; (ii) to help SOS developers identify areas for improvement of their SOS; and (iii) to help application developers and users make informed decisions about their choice of SOS server.

“…General test tools, such as Apache JMeter and LoadRunner, provide powerful capabilities for conventional performance and load tests. Utilizing these tools, experiments have been conducted to analyze the key performance factors of OGC web services [43][44][45]. However, general tools cannot parse service-specific data packages.…”

Abstract:One of the most widely-implemented service standards provided by the Open Geospatial Consortium (OGC) to the user community is the Web Map Service (WMS). WMS is widely employed globally, but there is limited knowledge of the global distribution, adoption status or the service quality of these online WMS resources. To fill this void, we investigated global WMSs resources and performed distributed performance monitoring of these services. This paper explicates a distributed monitoring framework that was used to monitor 46,296 WMSs continuously for over one year and a crawling method to discover these WMSs. We analyzed server locations, provider types, themes, the spatiotemporal coverage of map layers and the service versions for 41,703 valid WMSs. Furthermore, we appraised the stability and performance of basic operations for 1210 selected WMSs (i.e., GetCapabilities and GetMap). We discuss the major reasons for request errors and performance issues, as well as the relationship between service response times and the spatiotemporal distribution of client monitoring sites. This paper will help service providers, end users and developers of standards to grasp the status of global WMS resources, as well as to understand the adoption status of OGC standards. The conclusions drawn in this paper can benefit geospatial resource discovery, service performance evaluation and guide service performance improvements.

Abstract. This paper deals with cross-domain environmental aspects of noise mapping which is commonly understood as a stand-alone initiative. Scientific core of this research lies in the integration of noise mapping with interoperable data sources, where the European Union's INSPIRE (INfrastructure for SPatial InfoRmation in Europe) Directive is nowadays one of the main.Principles of noise mapping according to the END (European Noise Directive), OGC (Open Geospatial Consortium) CityGML specification, X3D (Extensible 3D) and application schemas in INSPIRE are depicted at the beginning. Special attention is then paid to the specifics of INSPIRE spatial data theme called buildings, including its extension possibilities. Motivations for 3D application schema of INSPIRE buildings are discussed while only 2D application schema is the legally binding one. On the other hand, 3D application schema is recommended by the INSPIRE Technical Guidelines. We also deal with OGC CityGML specification since it is the basis for the 3D application schema. We took a step forward to publish the results of noise mapping based on INSPIRE application schema through X3D technology on the Web. This enables to disseminate information on noise mapping to wide audience through next generation Web applications.The paper proposes formalised methodology on X3D-based application development through the XSLT (eXtensible Stylesheet Language Transformations). Noise mapping was taken as a use case. There are discussions on benefits and limitations of X3D visualization as well as differences between the X3D presentation and storage of 3D geospatial data according to INSPIRE application schema on buildings at the end.
