Exercise 4

Surface Modelling In this exercise, a representation of the surface of the Earth is generated using TINs (Triangulated Irregular Network) to generate a 3D surface model. A 3D model provides a very convenient representation for visualizing the surface of the Earth as well…

Exercise 5

Generating 3D Views of a Surface Contours (intersections of the surface at different elevations), hillshade (areas shaded depending on the sun’s height and direction) and aspect (angle that the surface faces relative to compass directions) are some of the other useful models that…
