Scope note

Text

This class comprises digital registration activities of properties of physical things using specialised equipment designed to capture physical signals from objects using sensors and record them as usable / interpretable digital outputs with specific set parameters, which typically affect the output and the interpretation of the results of the digital recording. The objects of registration / investigation typically include anthropogenic or natural features of the earth’s surface. An instance of digital registration involves the interaction of a sensor in the digital device, a physical thing measured and a digital object output which encodes certain properties of that object at the time of registration. Digital Process Units should be used to record digital measurement activities which have quantifiable outputs from mechanical inputs of signals which are carried out towards the end of having a scientifically evaluatable measurement output. Therefore, someone sketching an object, typing an observation in a note on a tablet etc ARE NOT instance of Digital Process Unit because they do not use sensors from a machine that automatically capture signals from a physical reality and transfer them into a digital form that can be used to interpret that reality based on knowledge of interpretation of the relevant signal and the physics etc. that are relevant for interpreting it. 

An instance of digital process unit comes into existence on the commencement of the registration procedure and is on-going so long as the operators were engaged in the purposeful action to produce a particular dataset. The instance of digital process unit ends upon successful execution of the registration process or abnormally if the registration is fatally interrupted by an incidental condition or the general abandonment of the process by the actors engaged in the registration.

Typical kinds of digital process unit include LIDAR scanning, photogrammetry, spatial recording via Total Station or drone inter alia.
