Élaboration d'un indice global de qualité de l'environnement urbain pour la ville de Sherbrooke
The growing urbanization rates throughout the world have negative effects on the natural environment of urban areas. However, there are very little means to measure the global quality of the environment in urban areas.The goal of this project is to realize a quantitative evaluation of the quality of the urban environment using ten environmental indicators for 47 sectors of the city of Sherbrooke. Then, each indicator is weighted and three indexes are created.The sectors with high quality environmental characteristics are clearly identified. In Sherbrooke, the center of town has a poor environmental index whereas the surrounding areas display a higher overall quality.The vegetation indicators extracted from high resolution satellite imagery account for an important part of the variation of the global index (r[superscript 2] = 0.85). Thus, remote sensing is an appropriate and effective way to evaluate the quality of the urban environment in Sherbrooke.
