==Physical and mathemicalmathematical interpretation==

The curvilinear coordinates of GST can explain physical processes applied to images. A well known pair of processes consist in rotation, and zooming. These are related to the coordinate transformation <math>\xi=\log(\sqrt{x^2+y^2})</math> and <math>\eta=\tan^{-1}(x,y)</math>.
