Abstract :
The three dimensional information of buildings is an important issue in urban monitoring, planning, management and various economic activities, and as a result of the tremendous development in the devices and remote sensing sensors, there is a need to obtain information about geographical locations with less cost, therefore the goal of this research is to extract the three dimensional information of buildings using shadow analysis appears in the 2D image and solving for the slope of view for this shadow without the need for additional data (another overlapping image or digital elevation model).
