COORDINATE TRANSFORMATIONS IN SURVEYING
In 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

A Lie group is a topological group that is also a smooth manifold, with some other nice properties.

people.cs.clemson.eduC.2 AFFINE TRANSFORMATIONS Let us first examine the affine transforms in 2D space, where it is easy to illustrate them with diagrams, then later we will look at the affines in 3D. Consider a point x = (x;y). Affine transformations of x are all transforms that can be written x0= " ax+ by+ c dx+ ey+ f #; where a through f are scalars. x c f x´
7 - Linear Transformations
www.ms.uky.eduLinear transformations are defined as functions between vector spaces which preserve addition and multiplication. This is sufficient to insure that th ey preserve additional aspects of the spaces as well as the result below shows. Theorem Suppose that T: V 6 W is a linear transformation and denote the zeros of V and W by 0v and 0w, respectively.
