Digital Tree management: Tree management in Hong Kong is an important aspect of the city's urban planning and environmental conservation efforts. In Hong Kong more than one million trees are registered and managed by the government. Particularly, regular tree maintenance and pruning are carried out to ensure public safety and tree health. The government's tree management teams conduct inspections, assess risks, and carry out necessary pruning or removal operations as required. Therefore, advanced sensing technologies are needed for the measurement of various parameters that monitor tree health and environment risk, such as: hyperspectral imaging for leave colour, acoustic tomography for trunk cavity, and ground probing radar for root distribution. In this presentation, the above-mentioned sensing technologies for the foster of digital tree management will be discussed.
