Crosscut simulations are an interactive 3D viewer that enables the visualisation of stems profiles and tree level product assortments.
ForestHQ provides innovative tools to simulate and optimise harvesting and growth models for future predictions. These tools are online and fully integrated with the inventory tools, enabling the valuation of timber products and revenue forecasting.

Terrestrial laser scanning is a ground-based version of the airborne LIDAR frequently used for terrain, vegetation and landscape high-resolution mapping over limited distances in the range of 50–300 m.
these are active sensors that emit laser signals to calculate distances and XYZ coordinates o fnumerous points based on the time delay of the returned laser pulses. They are able to record a dense array of distance return values which are assembled into highly detailed, digital 3-D landscape models that can be transformed into GIS DEMs for a morphometric measurements, topographic mapping and spatial analyses.
The spatial resolution of the resulting data is orders of magnitude higher than data derived from satellite- or airplane-based mapping and remote sensing techniques.
ForestHQ is designed to work with Terrestrial LiDAR data, creating an accurate 3D profile of each stem sampled.
ForestHQ is designed for the analysis of Terrestrial Laser data. LiDAR point clouds are processed to create very accurate stem profiles for each stem sampled, with a survey point on every square cm on the tree trunk surface.

The models can be analysed with the ForestHQ virtual harvest simulator the optimal timber products for each stem. This Simulator has a 3D viewer for the TLS data.
The main difference from taper equation models is that the 3D profiles created with LiDAR more precisely represents the real tree's shape, including defects and the sweep of the stem. The estimation of the assortments and volume of different timber products is therefore more accurate.
In the Viewer you can see the original point cloud data, the point data with the stems or only the stems:
virtual cutting optimisation
virtual cutting optimisation
ForestHQ's harvest simulator virtually cuts the 3D stems profiles exactly as a harvesting machine would in the forest.
This is the most accurate type of inventory for timber product estimation and valuation. We recommend this type of inventory for high quality timber stands.
The user can specify a weighted list of desired products and the system will optimise the timber products for each sample stem profile. Create and simulate various scenarios before the harvest to find the most profitable and economical cutting solution.
