Objectives
Sapin is a training module used during the Capsis training sessions.
Description
Sapin is an educational purpose module. It is a simple distance-dependent tree model. Tree properties are : id, x, y, z, dbh (cm), height (m), age, heightIncrement, dbhIncrement, crownBaseHeight, crownRadius.
Evolution is calculated for each tree for diameter and height. During the trainig session, a simple stochastic regeneration method is added.
Inputs
Inventory files contain one line per tree.
Inventory example with four trees :
| id | x | y | z | height | dbh |
|---|---|---|---|---|---|
| 45 | 9.53307761 | 40.70188426 | 16.80036643 | 22.95269581 | 46.6 |

Outputs
Usual outputs for distance-dependent tree models (see MaddModel).
