Implementation of a solar model and shadow plotting in the context of a 2D GIS: challenges and applications for the cooling effect of tree-covered based greening solutions in urban public spaces

Abstract : The adaptation of public spaces to episodes of intense heat is now a major challenge for the city. With this in mind, this article presents a contribution aimed at delineating and handling the ground shadow, whether it comes from buildings or from the tree canopy. After a comparison with shadows obtained via two reference tools, we present a real urban site that mixes shadows of different origins and, in addition, different indicators. The aim of these indicators is to assist urban designers with solutions that make it possible to distinguish the respective shadow contributions, their annual evolution and potential spatial or temporal continuities.
