Performing a growth prognosis will simulate tree growth on a stand (see Create input data using tree layer data on how to set up a compartment).

Step 1. Create a new GrowthCalculator.

var growthCalculator = new GrowthCalculator();

Advanced: Before using the growth calculator to simulate growth, its control tables can be accessed to specify parameters pertaining to the growth. Example of changing a setting in the "Production Model" control table Copy Code var pmcc = growthCalculator.GetControlTable<ProductionModelControlTable>(); pmcc.CalibrateHeight = false;

Short-hand methods

The compartment has short-hand methods for growing which will either create the growth calculator automatically, or accept a supplied growth calculator with specified settings. In either way, The result is an ApiState that holds a collection of data on the new state of the stand, including the new state of the tree layers.

ApiState result = compartment.Grow(5) //Grow 5 years;

All grow methods on the compartment take an optional growth calculator as their last argument. If supplied, this calculator will be used to simulate the growth.

var growthCalculator = new GrowthCalculator();
ApiState result = compartment.Grow(new DateTime(2030, 1, 1), growthCalculator);
