Abstract. Data collection on urban greenery plays a key role in its management and in evaluating the benefits it provides to society, including ecological, aesthetic, and health-related advantages. To manage urban greenery effectively, it is essential to seek ways to optimize the process of its inventory and assessment. Technological advancements in data collection methods offer new possibilities for making these processes more efficient.
