inventory ANALYSIS

ForestHQ automatically processes the inventory data (i.e. DBH and Height) using available volume models yielding stem volume.

For sample-based inventories the total variables are calculated using the tree stocking and strata areas estimated with the GIS tools.

Taper Equations

ForestHQ integrates taper equations for a better single tree volume estimation. If taper equations are available, the system automatically creates 3D models for each sampled tree.

This model is used for the estimation of volume but also used by the virtual cutting simulation tool to obtain an accurate estimation of the assortments and volume of different timber products.

Default local equations are used for the most common species, depending on your region. Local taper equations can also be implemented in ForestHQ. If you have a local equation that you want to use in ForestHQ, contact Treemetrics' customer support (support@treemetrics.com)

Volume Tables and Equations

Alternatively to the taper equations, ForestHQ can also use local volume tables and equations. If you have a local equation that you want to use in ForestHQ, contact Treemetrics' customer support (support@treemetrics.com)

Terrestrial Laser Scanner

ForestHQ is designed to work with Terrestrial LiDAR data, creating an accurate 3D profile of each stem sampled.

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 main difference from taper equation models is that the 3D profiles created with LiDAR more precisely represent 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.

The models can be analysed with the ForestHQ virtual harvest simulator the optimal timber products for each stem.

If you have collected data using Terrestrial LiDAR data and you want this data to be anlysed in ForsetHQ, contact Treemetrics' customer support (support@treemetrics.com)

Spatial Analysis

ForestHQ uses spatial analysis to estimate the inventory data based on the are defined in the "Productivity Zones ".

To improve the valuation and estimation of timber product yield, the Forest can be subdivided with the help of the background imagery.

Areas without trees, such as roads, streams, and other clearings can be removed. Areas of the forest with similar characteristics defined as Productivity Zones are analysed separately.

Carbon Calculations

ForestHQ also estimates the amount of carbon stored in the forest. There are several methodologies to estimate carbon, by default ForestHQ uses a formula widely used in online carbon calculators.

The advantage of ForestHQ is that the tree volume used for the carbon calculation is based on the field measurements and the taper equations described above. This makes ForestHQ more accurate in estimating the carbon content for your forest.

You can find more information about the calculations here. The default formula uses an average density of 450 kg/m3.

If you have an alternative formula to estimate carbon, that you want to use in ForestHQ, please contact Treemetrics' customer support (support@treemetrics.com).

Remote Sensing Inventory

ForestHQ supports single tree detection from remote sensing (i.e. Aerial LiDAR, Drones, high-resolution aerial stereo images).
