The development of personal computer software
coupled to an analytical stereoplotter allows major gains
in efficiency and accuracy in a number of forestry related
subjects. This thesis describes the operation of a system
developed by Carto Instruments.
This thesis demonstrates how area estimates might be
made in a systematic way...
