“…The publishing layer automatically sends the generated netCDF files of radial and total velocity data to a Thematic Realtime Environmental Distributed Data Services (THREDDS) server [59] responsible for data distribution. In particular, the netCDF files are attached in real-time mode to a THREDDS catalog that provides metadata and data access.…”

“…The catalog offers different remote-data-access protocols [59], such as open source project for a network data access protocol, Web coverage service, Web map service (OGC standards), as well as pure HTTP or NetCDF-Subsetter. These protocols allow for metadata interrogation and data download (even subsetting the data set in terms of time and space) while embedded clients, such as GODIVA2, NetCDF-JavaToolsUI, and Integrated Data Viewer, grant real-time data visualization directly via browser and allow for interactively navigating within the plotted maps, saving images, exporting-importing on Google Earth, and generating animations in selected time intervals.…”

In this paper, a high-frequency (HF) coastal radar network is described, which is established and maintained by the Institute of Marine Sciences (ISMAR) of the National Research Council of Italy (CNR) for the measurement of surface current velocities in the Gulf of Manfredonia, located in the semienclosed Adriatic Sea (Mediterranean Sea), during 2013-2015. The network consisted of four HF radars (HFRs) that provided hourly sea surface velocity data in real-time mode in a netCDF format compliant to the Climate and Forecast Metadata Conventions CF-1.6 and the INSPIRE directive. The hourly netCDF files are disseminated via a Thematic Real-time Environmental Distributed Data Services catalog supporting OGC compliant distributions and protocols for data visualization, metadata interrogation, and data download. HFR velocity data were compared with in situ velocity measurements by Global Positioning System tracked surface drifters deployed within the radar footprint. The results show a good agreement, with the root mean square (rms) of the difference between radial velocities from HFR and drifters ranging between 20% and 50% of the drifter velocity rms. The HFR data have also been compared with subsurface velocity profiles from an upward looking acoustic Doppler current profiler (ADCP) during winter 2015, to gain information on the correlation between surface and water column velocities. This information is especially relevant for fishery and coastal management applications, where transport of

Abstract:The quest for interoperability is one of the main driving forces behind international organizations such as OGC and W3C. In parallel, a trend in systems design and development is to break down GIS functionalities into modules that can be composed in an ad hoc manner. This component-driven approach increases flexibility and extensibility. For scientists whose research involves geospatial analysis, however, such initiatives mean more than interoperability and flexibility. These efforts are progressively shielding these users from having to deal with problems such as data representation formats, communication protocols or pre-processing algorithms. Once scientists are allowed to abstract from lower level concerns, they can shift their focus to the design and implementation of the computational models they are interested in. This paper analyzes how interoperability and componentization efforts have this underestimated impact on the design and development perspective. This discussion is illustrated by the description of the design and implementation of WebMAPS, a geospatial information system to support agricultural planning and monitoring. By taking advantage of new results in the above areas, the experience with WebMAPS presents a road map to leverage system design and development by the seamless composition of distributed data sources and processing solutions.
