How to read the information

Calculated result
An indicator, intersection, synthesis or visual produced from identified sources and documented rules.
Application example
Material showing a capability or method; it is not an official diagnosis or a commissioned result.
Not used for conclusions
A source, datum or validation not yet integrated. A missing value is never automatically treated as zero.
