Abstract:

A program for a programmable pocket calculator (Hewlett-Packard Model HP-67) calculates tree heights on permanent plots using rectangular coordinates and one vertical angle per tree. Subroutines are included to convert polar coordinates and plantation spacing data to rectangular coordinates, and to calculate vertical angles needed to locate specified heights. Model forms are included in a supplement. Forest Sci. 27:815-816.
