Accurate and Fast Plot Charting

Abstract

Plot charting is a necessary ingredient of many silvicultaral and ecological studies. Presently, the procedures standardised for such a charting are triangulation and optical square methods. Merits and limitations of these methods are listed and on the whole they are not only cumbersome to follow, but are also apt to include gross inaccuracies. A new method of plot charting is now proposed. It consists in the use of two measuring tapes for recording two coordinates of each tree position, with reference to a base line. This method has been extensively tried in the field and found to he extremely simple, fast, accurate and easy. It suits to all conditions of plot terrain and stocking per unit area.
