# Volume Calculation

Assisi supports a a large number of ways to calculate volume. This study is a discussion of what the options are and how volume is calculated. First an overview...

The volume in trees has historically been calculated using volume tables, volume equations or using tree taper. Assisi mostly uses the terms Volume Tables and Volume Equations to mean whole tree volume rather than the volume of logs. Assisi uses the term Log Segmenting to mean using taper models to calculate diameters at any point along the tree and therefore the volume of individual logs. The volume of logs is of course calculated using an equation, but for organizational purposes, Assisi groups volume calculate into these three types.

### Volume Tables

Volume Tables are tables of tree volume by species, DBH, height and often form class. The values were derived from field studies and were put into this form forâ€¦
