4.11 Measurement noun
An observation whose result is a measure
[OM]
4.12 Measurement verb
An instance of a procedure to estimate the value of a natural phenomenon, typically involving an instrument or sensor. This is implemented as a dynamic feature type, which has a property
containing the result of the measurement. The measurement feature also has a location, time, and reference to the method used to determine the value. A measurement feature effectively binds a
value to a location and to a method or instrument.
4.13 Observable, Observable Property noun
A parameter or a characteristic of a phenomenon subject to observation. Synonym for determinand.
[OM]
4.14 Observation noun
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.
[OM]
4.15 Observed Value
A value describing a natural phenomenon, which may use one of a variety of scales including nominal, ordinal, ratio and interval. The term is used regardless of whether the value is due to an
instrumental observation, a subjective assignment or some other method of estimation or assignment.
[OM]
4.16 Orientation
The rotational relationship of an object relative to a coordinate system. Typically expressed by relating the rotation of an object’s local coordinate system relative to an external reference
coordinate system. 4.17
Phenomenon
A physical property that can be observed and measured, such as temperature, gravity, chemical concentration, orientation, number-of-individuals.
A characteristic of one or more feature types, the value for which must be estimated by application of some procedure in an observation.
4.18 Position
The location and orientation of an object relative to a coordinate system. For body-based systems in lieu of point-based systems is typically expressed by relating the object’s local coordinate
system to an external reference coordinate system. This definition is in contrast to some definitions e.g. ISO 19107 which equate position to location.
4.19 Process
A process that takes one or more inputs, and based on parameters and methodologies, generates one or more outputs.
4.20 Process Method
Definition of the behavior and interface of a Process. It can be stored in a library so that it can be reused by different Process instances by using ‘xlink’ mechanism. It essentially describes the
process interface and algorithm, and can point the user to existing implementations.

4.21 Process Chain
Composite processing block consisting of interconnected sub-processes, which can in turn be Process Models or Process Chains. A process chain also includes possible data sources as well
as connections that explicitly link input and output signals of sub-processes together. It also precisely defines its own inputs, outputs and parameters.
4.22 Reference Frame
A coordinate system by which the position location and orientation of an object can be referenced.
4.23 Result
an estimate of the value of some property generated by a known procedure
[OM]
4.24 Sample
A subset of the physical entity on which an observation is made.
4.25 Sensor
An entity capable of observing a phenomenon and returning an observed value. In SensorML, modeled as a specific type of System representing a complete Sensor. This could be for example
a complete airborne scanner which includes several Detectors one for each band.
4.26 Sensor Model
In line with traditional definitions of the remote sensing community, a sensor model is a type of Location Model that allows one to georegister observations from a sensor particularly remote
sensors.
4.27 Sensor Platform
