Wayland, Mass., February 6, 2007 – The members of the Open Geospatial Consortium, Inc. (OGC) have approved the candidate OpenGIS Observations & Measurements (O&M) Specification for release for a thirty day public comment period. The document can be downloaded from http://www.opengeospatial.org/standards/requests/37.
The O&M candidate specification describes a framework and encoding for measurements and observations. This framework is required specifically for use by other OGC standards known as the OGC Sensor Web Enablement (SWE) capability as well as for general support for OGC compliant systems dealing in technical measurements in science and engineering.
The aim is to define a number of terms used for measurements, and the relationships between them. This document discusses observation, measurement, result, procedure, feature of interest, observed property, phenomenon, coverage and related terms, presented using UML class diagrams and in equivalent OGC Geography Markup Language (GML) conformant XML serializations. The scope of the specification covers observations and measurements whose results may be quantities, categories, temporal and geometry values, coverages, and composites and arrays of any of these.
