The application allows you to monitor trees in the city by automatically and manually tagging them. The tree map visualized in this way aims to analyze the municipal policy in the field of green areas and how trees affect the city and, above all, the health of residents. In the first phase, trees must be entered manually, then the created system will learn to recognize specific tree species from photos of leaves. In the second phase, the system that automatically recognizes trees will be able to collect points and take part in the game by searching for virtual birds located on trees throughout the city.
