COORDINATE TRANSFORMATIONS IN SURVEYING
mygeodesy.id.auIn 2D transformations all points lie in a plane. In these notes it is assumed that 2D transformations are transformations from one rectangular coordinate system (u,v) to another rectangular system (x,y). In addition, unless stated otherwise, a rotation is an angle considered to be positive in an

www.microsoft.comDec 10, 2006 · Table 1: Hierarchy of 2D coordinate transformations. The 2 ×3 matrices are extended with a third [0T 1] row to form a full 3 ×3 matrix for homogeneous coordinate transformations. Hierarchy of 2D transformations The preceding set of transformations are illustrated in Fig-ure 2 and summarized in Table 1.

Homogeneous 2D Transformations The basic 2D transformations become Translate: Scale: Rotate: Any affine transformation can be expressed as a combination of these. We can combine homogeneous transforms by ...
