Update VRI Volumes

Usage

Add the VRI_Tools.tbx toolbox to ArcToolBox to run these scripts. Each tool takes one argument - a featureclass that contains standard VRI formatted species fields.

NOTE: Must run AddVphFieldstoVRI first.

Script Descriptions

AddVphFieldstoVRI.py script

This tool adds fields to a VRI table for tabulating volume per hectare by species and calculates volume per hectare at the primary utilization level (17.5 cm dbh.)

Notes:

  • Adds new fields to an existing standard VRI table / feature class.
  • Calculates new fields with m3/ha for each species in the polygon.
  • This cript only needs to be run once for the feature class

AddTotVolFieldsToVRI.py script

This tool adds fields to a VRI table for tabulating volume (m3) by species group in polygon at the primary utilization level (17.5 cm dbh.)

Notes:

  • Run this script after adding the m3/ha field with the first script
  • The script should be run after completion of geoprocessing operations as the volumes are calculated for each polygon based on area
  • The table can then be summarized using the named species volume fields

Requirements

Requires ESRI ArcInfo licensing & ArcMap 10.0+.
