Forestry Survey - GVI LiDAR Scanning System and Processing Software in Australia
We are brining GVI forestry survey solutions into Australia, which include LiAir and LiBackpack LiDAR scanning systems and LiDAR360 software suite are the intelligent and automated solutions for collecting and managing the data for forestry survey. The solution can achieve the following functions:
• How many trees are there in a specific area?• How tall are the trees in the area that I am going to harvest timber from?
• How much carbon is stored in the biomass of the forests that I am studying?
• How much wood will get the forest in front of me yield at harvest?
If you are interested in finding the answers to the question above, take should a few minutes to read the following article which explains how GreenValley International (GVI) products can be applied to meet common forest inventory and management objectives.
Just a few years ago, people were only able to use remote sensing imagery and photogrammetric data products to determine the stocking level of a forested area. Information from these sources were combined with the field measurements collected by hand in order to answer the questions stated at the beginning of this article. But nowadays, with the recent advancement of LiDAR technologies, collecting forest inventory data has become easier than ever. LiDAR, as a high-accuracy detection instrument, can easily acquire measurements needed to produce three-dimensional point cloud models of forests with centimeter-levels of accuracy. Critical information can be extracted directly from these LiDAR point clouds models or calculated when coupled with other sources of forest inventory data.
GVI’s turnkey solutions for forest industries include hardware and software products that make LiDAR data collection, processing, and analysis possible

LiAir V70
The LiAir V70’s lightweight and portable design offers an wide-angle field of view and fast scanning rate that make UAV-LiDAR data capture efficient. There are few operating restrictions with this device and it has the adaptability to perform effectively in a wide variety of environments.
As a UAV-based 3D laser scanning device, LiAir V70 is well positioned to obtain detailed and accurate measurement data from hard-to-access upper forest canopy regions.
Key Performance Data
| Range Accuracy | ±2 cm |
| Weight | 1.1 kg(Incl.Camera) 0.9kg without Camera |
| Scan Range | 320 m @ 80% Reflectance |

LiBackpack DGC50
LiBackpack DGC50 is the flagship model in GVI’s LiBackpack Series. This system features dual LiDAR sensors and a panoramic camera that allow users to capture RGB information and generate colored point cloud. The device’s SLAM technology enables it to be used in GNSS-denied zones that are commonly found beneath forest canopies. From this scanning perspective, users can obtain the complete structure of the trunks of the trees and the lowest strata of forest canopies. Furthermore, DBH, canopy coverage, etc. can be readily extracted from this type of ground- based LiDAR data using tools found in GVI’s LiDAR360 TLS Forest Module.
Key Performance Data
| Range Accuracy | ±3 cm |
| Weight | 9 kg |
| Max Ranging Distance | 100m |
