3.8 inventory types & analysis
Embedded Files
ForestHQ has powerful tools to analyse several types of inventories:
Traditioanl inventory
Aerial LiDAR inventory
Single Tree Inventory
Terrestial Laser Inventory
Tools for fast, powerful and easy analysis of the inventory data online. Improving the precision of the inventory with fully automated data analysis and Automated TLS point cloud analysis. The system enables the use of custom algorithms and scripts to analyse the field data and combine them with remote sensing.
For the planning of the inventories Integrated online GIS, database with the data of the forest, accurate canopy cover area measured, stratification of the stand and sampling plots are used.

VOLUME TABLES AND FUNTIONS
VOLUME TABLES AND FUNTIONS
ForestHQ automatically processes the inventory variables (i.e. DBH and Height) using available volume models / tables yielding stem volume.
The total volume is calculated using the tree stocking and strata areas estimated with the GIS tools.
Go to Inventory Results to learn more about it.
DISTRIBUTION MAPS and reports
DISTRIBUTION MAPS and reports
ForestHQ automatically generates interactive reports and distribution maps after the field data has been received and analysed.
The user can display the distribution of several parameters across the stand (e.g. DBH, tree height, volume, average volume, stocking, etc.). These maps can be used to create new strata according the stand variables.
Go to Inventory Results to learn more about it.
TAPER EQUATIONS
TAPER EQUATIONS
ForestHQ also 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. The 3D models are used by the virtual cutting simulation tool to obtain an accurate estimation of the assortments and volume of different timber products.

TAPER EQUATIONS WITH TERRESTIAL LASER
TAPER EQUATIONS WITH TERRESTIAL LASER
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 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 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.

AERIAL LIDAR INVENTORY
AERIAL LIDAR INVENTORY
AERIAL LIDAR MODELING
AERIAL LIDAR MODELING
Combining aerial LiDAR and forest inventory information collected with the field inventory app, ForestHQ can create models to estimate stand variables.
These models can be used in nearby forests with similar characteristics.
The models are actualized as the new field data is loaded to the system. These models are mainly used in pure stands.
ForestHQ will implement these models over vast forest areas. This solution is recommended for general planning and resources management in areas where aerial LiDAR is available as it can provide a general overview of the available forest resources improving the efficiency and reducing field work.
ForestHQ mobile app and the online GIS system work in tandem to combine LiDAR data with field data and automatically create the models. These models are updated as new field data is gathered and uploaded to the system. Some benefits of this system include:
Automated modeling
Local models using your field inventory data
Stand or tree level models
Dynamic models learn as new field data is added to the system
The models can be use in other stands with similar characteristics
The results of the aerial LiDAR inventory include maps, tables and charts of the main forestry variables, such as DBH, height, stocking and timber volume.
SINGLE TREE INVENTORY
SINGLE TREE INVENTORY
SINGLE TREE MODELS
SINGLE TREE MODELS
Use remote sensing and single tree crown delineation for forest inventories. Combine mobile app field data with aerial tree crown delineation and Digital Height Models to create tree height, DBH and stem volume models at the single tree level. This type of inventory is recommended for pure stands and high quality timber.
ForestHQ can combine field data with single tree detection from remote sensing (i.e. Aerial LiDAR, Drones, high resolution aerial stereo images).
Single tree models are created to estimate the main tree variables such as DBH, height and tree Volume. These models are mainly used in pure stands.
