Impervious surface extraction with very high resolution imagery in urban areas: Reducing tree obscuring effect

Impervious surface is an important factor for evaluating the process of urbanization and its rate. In urban areas, there are a large number of street trees obscuring impervious surface, which will cause underestimation of impervious surface if it is directly extracted by classification of remotely sensed imagery. In order to solve this problem, this paper… CONTINUE READING
