OGC(R) Seeks Comment on Observations & Measurements Specification


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 Opengeospatial  
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
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.
The OGC� is an international industry
consortium of more than 335 companies, government agencies, research
organizations, and universities participating in a consensus process to
develop publicly available interface specifications. OpenGIS
Specifications support interoperable solutions that “geo-enable” the
Web, wireless and location-based services, and mainstream IT. The
specifications empower technology developers to make complex spatial
information and services accessible and useful with all kinds of
