4 March 2015 – The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC CF-netCDF 3.0 encoding using the GML Coverage Application Schema Standard.
This new addition to the netCDF suite of standards provides additional ways to serve complex multi-dimensional CF-netCDF data for use in geographic information systems (GIS) or other geospatial systems not capable of handling complex CF-netCDF data.
The OGC CF-netCDF 3.0 encoding standard (Climate and Forecast conventions for netCDF) has emerged as a widely used and well supported data model and encoding for domains such as atmospheric science, oceanography, climatology, meteorology, and hydrology. It supports multi-dimensional gridded data and multi-dimensional multi-point data representing space and time-varying phenomena.
This candidate standard specifies an extension of CF-netCDF 3.0. This extension is an encoding model of the CF-netCDF dataset that uses the OGC GML Application Schema – Coverages schema. The GML Application Schema – Coverages schema (GMLCOV) specifies the OGC Geography Markup Language (GML) coverage structures to be used by OGC standards. OGC coverages are two- (and sometimes higher-) dimensional metaphors for phenomena found on or near a portion of the Earth's surface, including, for example, Earth imaging data, regular and irregular grids, point clouds, and meshes.
The OGC CF-netCDF 3.0 encoding using the GML Coverage Application Schema Standard supports three different ways of encoding the CF-netCDF data model: binary, XML, or ASCII.
The documents for the candidate OGC CF-netCDF 3.0 encoding using the GML Coverage Application Schema Standard Standard are available for review and comment at (http://www.opengeospatial.org/standards/requests/131).
The OGC is an international consortium of more than 500 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that “geo-enable” the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
