A method to map land use impacts on microclimate regulation supply in urban environments

Year: 2024

Type: article

Abstract: Land use impacts land surface temperature (LST), especially in urban areas where anthropogenic materials have a high capacity to store energy. Nevertheless, cities have many other land uses (e.g., forests, lawns) that can reduce LST and contribute to high microclimate regulation. In this work, we develop a method to map land use impacts on microclimate regulation supply using an Unmanned Aerial Vehicle (UAV). A detailed methodology was developed for 1) UAV's mission planning, 2) field data collection for method validation, 3) RGB and thermal mission reconstruction, 4) land use classification, 5) data extraction and 6) spatial and statistical analysis. The method developed can be beneficial to local authorities and transferable to other realms. It will allow us to understand the impacts of different land uses on microclimate regulation. For this, an area with heterogeneous land uses was used as a test site.•A novel methodology was created to map land use impacts on microclimate regulation supply in urban areas;•High-resolution UAV RGB and thermal imagery for land-use classification and surface temperature analysis;•The method can help understand the capacity of the different land uses on microclimate regulation.
