4.1 Measurement

An observation whose result is a measure. [OGC 07-022r1] 4.2 Observable Parameter or a characteristic of a phenomenon subject to observation. [OGC 07-022r1] 4.3 Observation An act of observing a property or phenomenon, with the goal of producing an estimate of the value of the property. A specialized event whose result is a data value. [OGC 07-022r1]

4.4 Observation Offering

An observation offering is a logical grouping of observations offered by a service that are related in some way. The parameters that constrain the offering should be defined in Copyright © 2007 Open Geospatial Consortium, Inc. All Rights Reserved. 3 such as way that the offering is “dense” in the sense that requests for observations that are within the specified parameters should be unlikely to result in an empty set.

4.5 Phenomenon

Characteristic of one or more feature types, the value for which must be estimated by application of some procedure in an observation. [OGC 07-022r1]

4.6 Procedure

Method, algorithm or instrument. [OGC 07-022r1]
