Abstract

The research project focused on the use of Terrestrial Laser Scanning, for use in forest inventory for monitoring of forests. Typically, TLS has been used in the built environment, eg building information modelling, mining, architecture and engineering. In recent years advancements in TLS technology have allowed it to be applied to a greater amount of applications, including natural resource management and monitoring of forest resources.

Forests are one of Australia's most valuable natural assets. They are highly valued and have many uses and benefits for our society. Just over 20% of Australia is covered by native forest. There is an increasing need to measure and monitor the extent and condition of Australia‟s
forests. A National Forest Inventory (2003) highlighted the importance of having consistency in the collection of forest data. In 2006, the Continental Forest Monitoring Framework (CFMF) was identified by State and Federal governments of Australia as a means to streamline and standardise the collection methods of forest related information. Could TLS be of use here?

A stand of planted rainforest trees in central Murwillumbah, northern NSW, was chosen as the scan site. Approximately 7 scans were undertaken on the 60m x 60m site in an attempt to create a 3D point cloud of the entire stand. See figure 1 for a view from the Scanner.

Despite some issues with registration, enough data was captured to be representative of a 40m radius sample plot. Many measurements and forest characteristics were able to be
extracted to an accurate standard. To be used long term to gather forest related data, further investigation is required to ascertain the optimal type of instrument, plot size, resolution settings, number of scans for a site, software, targets used and other best practices required to generate an optimal repeatable method for forest data capture, comparison and storage.

The TLS would be suitable for under canopy measurements and long term monitoring, measuring and data extraction of forest based data. TLS is able to gain a snapshot of a
particular forest location then perform that same snapshot and compare the change over time. If a rigorous system is developed for monitoring forestry, TLS would definitely have
advantages.
