OGC Seeks Comments on NetCDF Enhanced Data Model Extension Standard

These specifications are under control of the Standards Working Group and will be released after the edits and revisions. For the most current version please check our Standards Page.
Description:
The Open Geospatial Consortium (OGC®) membership seeks comments on an OGC candidate standard, the Network Common Data Form (NetCDF) NetCDF Enhanced Data Model Extension Encoding Standard. This document specifies an extension to the existing OGC Network Common Data Form (NetCDF) Core Encoding Standard version 1.0.
The OGC netCDF encoding supports electronic encoding of
geospatial data, specifically digital geospatial information representing
space- and time-varying phenomena. NetCDF
(network Common Data Form) is widely used internationally to communicate
and store many kinds of multidimensional data, although it was originally
developed for the Earth science community. The netCDF data model is particularly well suited to providing data in
forms familiar to atmospheric and oceanic scientists: namely, as sets of
related arrays. NetCDF was developed
and is maintained and actively supported by the Unidata Program Center (http://www.unidata.ucar.edu) of the University Corporation for
Atmospheric Research (UCAR).
The netCDF classic
data model has previously been established as the core OGC CF-netCDF
standard. With this extension to the
core standard for the enhanced data model, complex data structures can be
represented very easily, allowing for more efficient programming. In
performance-critical applications, the enhanced model provides significant
benefits. Moreover, if existing HDF5 (Hierarchical Data Format, release 5)
applications that depend on groups, user-defined types, unsigned types, or strings
produce or use these data, the netCDF enhanced data model is required. The
recently introduced candidate NetCDF Enhanced Data Model Extension
Encoding Standard is the latest step
in a longer-term plan for establishing CF-netCDF as an OGC standard for binary
encoding, which will enable standard delivery of data in binary form via
several OGC service interface standards, including the OGC Web Coverage Service
(WCS), Web Feature Service (WFS), and Sensor Observation Service (SOS)
Interface Standards.
