Level of information (LOI)
used to describe non-geometrical information
LOI + LOD = Level of information need
LOI it is PAS 1192 term, now superseded by BS EN ISO 19650 term …’Level of information need’…
BS EN ISO 19650:2018 set of standards introduced a new term ‘Level of information need’ which is designed to replace the terms used in PAS1192 such as Level of model definition/level of detail (LOD) and level of information (LOI). Since the PAS1192-2:2013 has been withdrawn the new BS EN ISO 19650-2:2018 term Level of information need shall be used
The term LOI will remain to be used in conjunction with LOD (Level of Detail) – both terms can be contained under the umbrella of the new ISO term level of information need
For an up to date definition of the term Level of information need go to Information Management according to BS EN ISO 19650 Guidance Part 1 quoted below:
6.5.1 What is the level of information need and why do we need it?
Information is required for a purpose, such as to perform a task or support a decision.
The level of information need is defined to enable the right level of information to be provided
to satisfy the information related purposes at each information exchange. It is important to avoid
the delivery of too little information, which increases risk, and the delivery of too much
information, which is wasteful.
The level of information need is a broad concept which represents the framework for how the
“richness” of each information deliverable is going to be defined. There are many different ways
to express the level of information need, including the richness of geometrical details and the
richness of datasets.
Note that ‘level of information need’ should not be abbreviated.
