Description: 

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 below

Description: 

The OGC seeks public comment on a candidate OGC® Moving Feature Encoding Standard. Part I of this candidate standard provides a standard way of encoding moving feature data in an XML encoding in the form of an OGC Geography Markup Language (GML) application schema. Part II provides a standard way of encoding moving feature data in a simple CSV (comma-separated value) format.

The candidate OGC® Moving Feature Encoding Standard is available below. Comments are due by 23 August 2014.

The advance of mobile computing and internet-connected sensors (including sensors and GPS transponders in cell phones and notebook computers) brings with it a rapid rise in applications for moving feature data, typically representing vehicles or pedestrians. Many innovative moving feature applications will require the overlay and integration of moving feature data from different sources. Examples can easily be imagined for disaster risk management, traffic information services, security services, navigation for robots, aviation or maritime traffic monitoring, and wildlife tracking and conservation. Most current applications, however, are limited to single-source moving feature data.

More efficient moving feature data exchange will result in a requirement for massive data handling. The CSV style encoding provides an efficient and easily understood standard for encoding lightweight data records, which will be important for many applications involving large data volumes and real-time response. The GML application schema style encoding for Moving Features provides for the encoding of more complex spatial information.

This standard addresses only “rigid” moving features, such as vehicles, as opposed to those that deform, such as flood water, and it does not address moving features whose descriptions contain other moving features that must be updated as the feature moves, such as control surfaces on an unmanned aerial vehicle (UAV). It also is for archived Moving Feature data only, and not for live feeds from sensors.
