The OpenGIS Consortium (OGC), an industry group, has developed COM, CORBA and Java interface specifications allowing vendors to develop mutually interoperable geospatial software. OGC established the Coordinate Transformation Working Group (CT-WG) in April 1998. The working group developed a Unified Modeling Language object model of coordinate systems (CS) and coordinate transformations (CT) in...

In the Digital Forestry area, there is more and more requirements for spatial information connection and processing. From a prototype of geospatial computational grid (GCG), the relationship between the geospatial computational grid and OGC Interoperability protocols is proposed in this paper. A prototype of geospatial information grid is given in this paper. Digital Forestry Grid is proposed a...

An intelligent geoportal orchestrates (automatically coordinate) web services to prepare, discover and present information to the user. Implementations of web service standards by the Open Geospatial Consortium (OGC) and ISO/TC 211, Geographic information/Geomatics, such as, the Web Map Service (WMS), Web Feature Service (WFS) and Styled Layer Descriptor (SLD) enable the display of spatial data...

The standards developed by the Open Geospatial Consortium (OGC) provide a broad foundation for web-based geographical applications. As one of these the OGC Sensor Web Enablement (SWE), which comprises standards for the consumerand provider-oriented sensor viewpoint, allows data requests of real-time sensor measurements and observations, abstracting from the inherent sensor particularities. The ...

This paper addresses the discovery of sensors within the OGC Sensor Web Enablement framework. Whereas services like the OGC Web Map Service or Web Coverage Service are already well supported through catalogue services, the field of sensor networks and the according discovery mechanisms is still a challenge. The focus within this article will be on the use of existing OGC Sensor Web components f...

Open GIS Consortium (OGC) Geospatial Web services have been introduced to overcome spatial non-interoperability problem associated with most geospatial processing systems. Although OGC geospatial Web services provide interoperability among heterogeneous geospatial processing systems, in some cases they can not provide required performance and efficiency. This paper proposes a hybrid architectur...

Taiwan is located at the collision boundary of the Philippine sea plate and the Eurasian plate. The mountain terrain is precipitous and the region, on the whole, is characterized by fragile rocks and frequent seismic activity. In addition, the concentrated torrential rainfall brought by typhoons cause extensive disasters, debris flow, the most serious disaster caused by torrential rainfall, lea...

Abstract Background Locally advanced oesophageal cancer is usually treated with neoadjuvant treatment (NAT) followed by surgery. Venous thromboembolism (VTE) a recognised complication in these patients. Those who develop VTE may have an inferior vena cava filter placed prior to surgery reduce the risk of further complications. This study aimed identify specific risks for during oesophagogastric...

SUDPLAN is currently developing a technical solution for Model Web/Observation Web in the Climate Change usage area. Proposed solution is based on the Open Geospatial Consortium standards, and follows the ideas expressed in SANY Sensor Service Architecture (SensorSA). SUDPLAN also continued the development of the SANY software, resulting in native SOS, SPS and 2D coverage support in ”Time Serie...

The target of the Open Geospatial Consortium (OGC) is interoperability of geographic information, which means creating opportunities to access geodata in a consistent, standardized way. In the domain of sensor data, the target will be picked up within the OGC Sensor Web Enablement Initiative and especially reached through the Sensor Observation Service (SOS) standard. This one defines a service...
