Detecting motion-based video change, such as different types of motion video or applications using different change detection algorithms in a Web system, is difficult. This paper designs and implements architecture for a real-time or near real-time on-demand motion video change detection system using the Sensor Observation Service (SOS) and the Web Processing Service (WPS) in the Sensor Web env...

The article describes the environment of WPS-based (Web Processing Service) distributed services, that uses scenarios in JavaScript programming language in order to integrate services with each other. The environment standardizes data processing procedures, stores all services-related information and offers the set of basic WPS-services.

eScience is an umbrella concept which covers internet technologies, such as web service orchestration that involves manipulation and processing of high volumes of data, using simple and efficient methodologies. This concept is normally associated with bioinformatics, but nothing prevents the use of an identical approach for geoinfomatics and OGC (Open Geospatial Consortium) web services like WP...

Web Processing Services (WPS) expose processing functionality using Web Service technology. The WPS specification describes the interfaces to publish geospatial processes on the Web. It includes a platform-neutral and several platform-specific versions of its interfaces. Some of the platform-specific interfaces are mandatory and others are optional. In this paper, we present a method to support...

The aggregation of web services in order to achieve a common goal is a basic concept in Service Oriented Architectures (SOA). This paper demonstrates OGC Web Services (OWS) aggregation based on a simulated bomb threat scenario which is a possible disaster management example. Web services are aggregated based on the OGC Web Processing Service (WPS) interface. Here the concept of a “Composite-WPS...

We sketch the main software components developed in the project RichWPS, which aims to support end users (no IT experts) to make better use of distributed geodata processing through the OGC Web Processing Service (WPS). These services include a service orchestration solution (modelling GUI and orchestration engine), several supporting modules and services (like a semantics-enabled service regis...

Housing market analysts typically rely on Geographic Information Systems (GIS). The new Web Processing Service (WPS) standard proposed by the Open Geospatial Consortium (OGC) offers an alternative that supports desktop GIS analysis functionalities over the Internet via a standardised interface. This article presents how the WPS specification was applied for housing market analyses and demonstra...
