The Murray-Darling Basin Authority (MDBA) is a Commonwealth agency responsible for the sustainable management of water resources in the Murray-Darling Basin. The Authority has identified the need for web mapping infrastructure to provide online access to the Authority’s spatial information via discovery, access and publishing tools. In line with the requirement to harmonise the Authority’s onli...

Environmental modelling workflows are often tedious due to heterogeneity of data sources, types and formats. This paper discusses how a software framework based on Open Geospatial Consortium (OGC) standards may facilitate the workflow steps and improve their flexibility by supporting data access, processing, and decision-making. The software framework is designed based on OGC standards, which c...

The OGC Interoperability Program is a source of innovation in the development of open standards. The approach to innovation is based on hands-on; collaborative engineering leading to more mature standards and implementations. The process of the Interoperability Program engages a community of sponsors and participants based on an economic model that benefits all involved. Each initiative begins ...

Web resources that are not part of any Spatial Data Infrastructure can be an important source of information. However, the incorporation of Web resources within a Spatial Data Infrastructure requires a significant effort to create metadata. This work presents an extensible architecture for an automatic characterisation of Web resources and a strategy for assignation of their geographic scope. T...

An efficient access to the contents provided through OGC web services, widely used in environmental information systems, is usually achieved by means of caching strategies. Service-owners may be interested in expressing the conditions required to allow for this. If these conditions are expressed in a machine-readable way, automatic harvesters can be programmed to follow them when caching those ...

The Open Geospatial Consortium (OGC) defines a number of standards (both for data models and for online services) that have been widely adopted in the Geographical Information System (GIS) community. In this paper we will describe our group's efforts to implement GIS services according to OGC standard specifications in accordance with the Web Services approach. This paper focuses on the Web Map...

In recent years the OpenGIS technology standards have been developed by the Open Geospatial Consortium (OGC), which provide the essential basis for syntactic interoperability of geographic information services, also gives an opportunity for data interoperability, data integration and data sharing between different emergency management agencies. However finding suitable services and visualizatio...
