Metsandustööriistad DAP / maht

Seisva puu mahukalkulaator (DAP, kõrgus, vormitegur, salvestatud valemid)

Estimate standing puu volume from DAP, kõrgus, form factor, and formula presets.

GS1 andmed is parsed into AIs where possible, and unrecognized sisend is still shown in a usable format.

DAP and kõrgus convert into one puu volume tulemus ppm(w/w)=mg/kg on selgesõnaliselt näidatud Ligikaudne/täpne režiim koos valemi kuvamisega Salvesta and jaga user-defined formulas
Seotud tööriistad
Estimate single-puu volume from DAP, kõrgus, and form factor in one pass.
Swap formula presets to reflect regional, liik, or company-specific standards.
Switch the tulemus between m³, ft³, and board feet without changing the underlying calculation.
Salvesta your own formulas in the brauser and ekspordi or impordi them as JSON.

Valemid
DBH

Diameter at breast kõrgus. The tüvi diameter measured at the local breast-kõrgus convention.

AI

Application Identifier. Codes such as 01, 17, and 10 describe the meaning of the following väärtus.

Rinnaspindala

The tüvi cross-sectional pindala derived from DAP.

board feet

An equivalent display ühik for cubic volume in this tool. It is not a local log rule.

Kasvustaadium

A reusable formula template that carries its ühik basis, coefficients, and märkused.

Valemid

DBH / H / f
  1. G = π × (DBH / 2)^2
  2. V = G × H × f
  3. V = a × DBH^b × H^c
  4. V_bf = V_ft3 × 12

Olulised märkused
Board feet is an equivalent display ühik in this tool. It is not the same thing as Doyle, Scribner, or International log rules.
DAP conventions vary by region and organization. Match the saved formula to the field standard you actually use.
If ajalugu saving is enabled, the original sisend string is stored in this brauser's localStorage. Be careful on shared devices.
Saved formulas stay on this device unless you ekspordi them.
