SimilarityTransformation

Creates objects of class SimilarityTransformation from control points or 
 directly from parameters

 spatial 

Applies affine and similarity transformations on vector spatial data (sp objects). Transformations can be defined from control points or directly from parameters. If redundant control points are provided Least Squares is applied allowing to obtain residuals and RMSE.
