A New Computerized System for Tree Ring Measurement and Analysis

摘要: The Tree Ring Measurement System provides a relatively inexpensive, accurate, and efficient method of measuring diameter increments on cores or stem analysis disks while eliminating data recording and keypunching errors. The system consists of a micro-scope, sample positioning mechanism with optical encoder, and IBM PC/XT/AT microcomputer. The interactive menu-driven Fortran program displays diameter increments during data acquisition, and allows data to be plotted, edited, displayed, or remeasured at any time. The software can be modified to meet the user's requirements.
