UN31: Need to link tree planting parcels to estimate the number of trees planted

Description

Tree counting require VHR satellite imagery to accurately and efficiently determine the number of trees within a specified area. This approach offers significant advantages over traditional ground-based methods, as it enables rapid, cost-effective, and large-scale tree counting without the need for time-consuming field surveys. This data, coupled with the ability to monitor changes over time, aids in assessing the value of forestry assets, estimating timber volume for investment or insurance purposes, and evaluating the environmental impact of forestry investments.

Main processing steps

The process starts by inspecting optical VHR imagery (≤ 0.5 m) to identify a sample of individual trees to build a training dataset for a deep learning model. Then a deep learning model to be trained in optimoum way to detect the individual tree and, subsequently, identify the number of trees.

Constraints and limitations

• Cloud presence
• Cost of VHR imagery
• Lack of training data
• Global inconsistency due to the diversity of tree species.
• Limitations in homogeneous forests where the trees are connected.
