BaKIM is a cooperative project of the City of Bamberg and the University of Bamberg, aiming to improve the care of city trees and wooded areas. For this purpose, a fixed-wing drone gathers RGB, multispectral, and thermal data, which are evaluated with different AI approaches. The obtained information shall support city arborists and foresters via a web application. This improves procedures in both organisations and continuously enhances and expands the database. Towards the project's end, other municipalities are given access to the system, and the development of professional free software development is prepared.
