Public and street trees are a significant investment.
Cities are striving to increase canopy cover to combat climate change, with the average city surveyed aiming for a 49% increase. To deliver this step change, they need a step change in information.
But manual surveys all hugely expensive, time consuming and don't capture private trees.
Tree Monitoring with Advanced Satellite Technology
Tree health monitoring is a critical need for municipalities. Given the need to increase tree plantings, municipalities cannot afford to lose existing trees, which are threatened by increased droughts due to climate change. But with hundreds of thousands of trees for large cities to manage, it is impossible to visit every tree for a regular check-up.
This is why WEO has developed tracking of tree defoliation and discolouration to give cities and early warning sign of which trees to visit.
To understand how tree canopy coverage is changing over time, on both public and private land, growth monitoring is particularly important.
That's why TreeMonitor provides regular updates on tree growth and can identify new tree plantings.
Some of our clients also wish to understand biodiversity or vegetation connectivity information within their city. Therefore TreeMonitor data can be combined with other vegetation information on shrubs and grass to understand these elements.
How it works
Our tree monitoring product is primarily based on data from the Copernicus Sentinel-2 satellite. This dataset ensures we can obtain global coverage with new imagery available every 5 days. This regular revisit ensures that there is a cloud-free satellite image available to provide tree growth updates every season.
WEO then utilise deep learning techniques trained on centimeter resolution lidar and orthophotography to 'zoom in' to a higher resolution than the raw 10m resolution of Sentinel-2.
