Urban surface morphology is an important key factor in determining the temporal variation of thermal anisotropy. This study uses drones based high-resolution Digital Surface Models (DSM) to explore the impact of morphological urban variability expressed by terrain factors such as diurnal anisotropy patterns, sky view factor, solar radiation and solar duration effects on the urban heating island. The goal of this study is to build a topo-climatologic map from the terrain factors and determine its effects on the Urban Heating Islands. a test area of 2 square km was selected, including open grasslands, forests, and built-up areas. Itinerant measurements are made using portable sensors to measure temperature and wind direction in the study area. the measurement points are chosen according to the result of the topographic map and the topo climatologic map. the measures taken allowed us to study the temperature of the region during the day and at night and to detect the urban heat island of the region.
