Interactive 3D city modeling based on Google earth
The demand for realistic visualization of Three-Dimensional (3D) city models is fast growing. However, it used to take numerous work to generate 3D city models using laser scanner data and in combination with 3D digital terrain models textured with high resolution orthophotos. With the help of Googl...
