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 :
