Hansoojung Develops Precision Technology for Measuring Carbon Absorption in Gardens and Urban Forests

The Korea National Arboretum and Garden Management Office (hereinafter referred to as Hansoojung) announced on May 21 that, in collaboration with Kookmin University, it has developed a technology that enables precise measurement of carbon absorption in urban gardens and forests using drone LiDAR.

Previously, Hansoojung signed a memorandum of understanding with Kookmin University last year and began developing technology to enhance carbon absorption. The technology developed by Hansoojung and Kookmin University is a calculation formula (relative growth model) that can measure the carbon storage (aboveground biomass) of trees in community gardens.

The relative growth model is a mathematical model that allows the measurement of biomass based on external characteristics without cutting down the tree. It is a calculation formula that estimates carbon storage using only external information such as the height and width of the tree.

External information such as tree height, branch width, and trunk diameter is measured non-contact using LiDAR equipment mounted on a drone.

Hansoojung emphasized that by utilizing this method, it is possible to collect carbon information over a wide area in a short period of time without the need for people to visit the site directly, thereby significantly reducing both costs and time.

This technology development was carried out as part of Hansoojung's project, "Development of Tree Measurement and Monitoring Technology Using Information and Communication Technology (ICT) for Community Gardens." The results of the development were published in the April issue of the Journal of Korean Cadastre Information Society last month.

Shim Sangtaek, Chairman of Hansoojung, said, "This technology development is meaningful in that it scientifically proves the carbon absorption function of community gardens and establishes a foundation for quantitative management," adding, "Hansoojung will continue to systematically manage the carbon storage capacity of all urban green spaces, including community gardens, to provide solutions for achieving a carbon-neutral society."
