When importing a stand register to be used as input data the program simulates tree lists using diameter distribution functions. For every tree created the tree height is calculated using height functions. These functions are based on sample tree data from the National Forest Inventory and covers all regions in Sweden. For specific stands, the actual tree heights will of course differ from those projected. Therefore, it is possible to let the system adjust the calculated heights. The purpose of using a height function is then that to help obtain a realistic height distribution, so that not all trees have the same height.
Calibration is done in two steps, first for each tree species, is species-wise mean height exist in the import file, and then for the for the stand as a whole, given that the mean height or the stand is available. The calibration is done separately for each species and tree layer (main layer and overstorey trees).
