A precursor paper (also available as an OGC White Paper) provides a high-level overview of and architecture for the Open Geospatial Consortium (OGC) standards activities that focus on sensors, sensor networks, and a concept called the “Sensor Web”. This OGC focus area is known as Sensor Web Enablement (SWE). For readers interested in greater technical and(More)
DataFed is a distributed web-services-based computing environment for accessing, processing, and rendering environmental data in support of air quality management and science. The flexible, adaptive environment facilitates the access and flow of atmospheric data from provider to users by enabling the creation of user-driven data processing value chains. The(More)
In a multi-vendor environment, development of the Internet of Things (IoT) will be limited without the emergence of open, consensus standards that enable collaboration. Such standards will define an infrastructure that raises the level of services and quality of information for the marketplace thereby providing more opportunities, particularly for the(More)
ALTHOUGH THE QUESTION OF WHO PAYS FOR open data is important (“Who will pay for public access to research data?”, F. Berman and V. Cerf, Policy Forum, 9 August, p. 616), a greater challenge lies in implementing the institutional and cultural changes required before data from government-sponsored research can be openly shared. The Offi ce of Science and(More)
Geosciences can only achieve their potential through the fusion of diverse Earth Observation and socio-economic data and information. In a multiple provider environment, fusion is only possible with an information system architecture based upon open standards. This paper reports on the results of a study of “To-Be” fusion environment based on open(More)
With the increasing pace of change in computing technology, islands of relative stability become important to reaping the benefits of geospatial information. Geospatial standards are bases for persistent developments in the complex adaptive ecosystem of geospatial computing technology. Standards are the backbone of the Geoweb and will be also for the(More)
Geospatial informatics has achieved a level of maturity that is bringing spatial data to ever more applications. Examples include web mapping, 3-D browsers, spatial data infrastructures, sensor webs, and location based services. Key principles to this achievement include: robust open source and proprietary implementations; consistent geospatial concepts(More)
