Area types handled by the system and used in table views and reports
Name	Description	Unit	Result category (database table)
Area	Productive area for treatment unit	ha	TreatmentUnit
AreaFactor	Representative productive area for treatment unit if land use class is produtive forest, otherwise total areal.	ha	TreatmentUnit
AdjustedAreaFactor	AreaFactor adjusted for number of inventory years when using NFI-data as data source. This area is always used in Heurekas report generator.	ha	TreatmentUnit
TreatedArea	Proportion of treatment unit that has been assigned a certain treatment. Normally 1 if a treatment has been applied. Courld be less than 1 if a treatment unit has multiple plots (prediction units), and a treatment has been applied only on a subset of plots. For example when using FMPP-data and partial thinnings are allowed. When creating reports on treatment areas, Heuireka is automatically adjusting for TreatedArea if ypu use the Area summation type in the report generator.	proportion [0, 1]	TreatmentUnit
Impediment	Proportion of total area that is impediment. Note that there is no result variable for result category TreatmentUnit in Heureka for total area when the land use is productive forest. To calculate it, use formula Total area = AreaFactor/(1-Impediment)	proportion [0, 1]	TreatmentUnit
