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 |
Area types in stand register import file (and result category StandObjectData)
| Name | Column name in csv file | Description | Unit | Result category |
|---|---|---|---|---|
| Productive Area | ProdArea | Productive area in stand register import file. Should equal TotalArea minus ImpedimentArea | ha | StandObjectData |
| Total Area | TotalArea | Total area in stand register import file | ha | StandObjectData |
| Impediment Area | ImpArea | Impediment area | ha | StandObjectData |
| Nature Conservation Area | NCArea | Produtive area that may be set aside in simulations depending on your control tables settings | ha | StandObjectData |
