Upscaling of Terrestrial Laser Scanning through fusion with remote sensing data

In Issue54 by FIEALeave a Comment

Terrestrial laser scanning (TLS) is increasingly being fused with air/spaceborne Lidar to characterise vegetation structure across a range of forest ecosystems. This article explores the potential of this approach to support scaling up for larger areas in practice.

TLS is an important tool for plot-scale measurements of tree and forest structure. These local measurements are meaningful to support the quantification of a forest’s carbon balance and long-term forest monitoring. Typically, the upscaling from individual trees to local plot measurements to regional or national estimates is facilitated by the coupling of TLS data with airborne and spaceborne Lidar. There has recently been an increase in the fusion of TLS data with air/spaceborne Lidar to characterise vegetation structure across a range of forest ecosystems.

TLS data can already provide accurate estimations of tree volume and biomass. This is crucial to monitor carbon changes as a result of climate change, as well as for forestry and forest management.
