One of the best ways to understand SensorML encodings is to study examples with an understanding that they help present what is possible.
SensorML is used to define both physical and non-physical processes. Physical processes can include, for example, detectors, actuators, sensor systems, samplers, etc. Non-physical processes can include a wide variety of processing used within the act of measurement or modeling, including, for example, spatial transforms, sensor models for geolocation, QC tests, image processing routines, classification routines, etc.
