The purpose of the project was to determine what information of significance to forest surveys could be obtained from recent advances in pulsesd laser technology. The project involved four phases: 1) the preliminary investigation of pulsed laser waveforms (return pulses) as influenced by the forest and other terrain features, 2) development of hypotheses and procedures for the extraction of forest stand information from laser data, 3) a formal test of hypotheses concerning the use of pulsed lasers to produce forest survey information, and 4) the assessment of applications and benefits.
The results of the investigation of basis properties of pulsed laser returns, informal and formal statistical tests, conclusions, and recommendations on the direction of further work are reported. Particularly promising results were obtained using pulsed lasers to estimate heights and densities of forest stands, and in the potential of using pulsed lasers for forest and terrain profiling.
