Estimate height

Description

Estimate height to a given top diameter given species, diameter, site index, and stand basal area. The height equation is applied by the function apply_height_eq.

Usage

estimate_height(spcd, dbh, site_index, top_dob, stand_basal_area)

Arguments

spcd	vector of FIA species codes
dbh	vector of DBH observations in inches
site_index	vector of site index estimates (base age 50)
top_dob	vector of outside-bark diameter values to which height will be estimated
stand_basal_area	vector of stand-level basal area estimates corresponding to the stems

Value

vector of height estimates

Examples

estimate_height(
  spcd = c(541, 371, 95, 73),
  dbh = c(10, 11, 12, 13),
  site_index = c(60, 65, 60, 70),
  top_dob = c(4, 4, 9, 10),
  stand_basal_area = 80
)
