What is the 2-D COORDINATE TRANSFORMATIONS program?
2-D COORDINATE TRANSFORMATIONS is a 2-dimensional coordinate transformation program, designed to supplement existing Surveying and Engineering coordinate geometry software and other Survey/GIS software. It includes the Conformal Four Parameter Linear Transformation familiar to many surveyors, but also includes other Non-Conformal and Conformal Two-Dimensional Coordinate Transformations. The Non-Conformal Two- Dimensional Coordinate Transformations include the Six Parameter Affine Transformation, the Eight Parameter Projective Transformation, and General Bivariate Polynomial Transformations from the 2nd to the 5th powers. The Conformal Two-Dimensional Coordinate Transformations include the Four Parameter Linear Transformation and Conformal Bivariate Polynomials from the 2nd to the 11th powers. A brief description of each of these transformations, including the mathematical models which define them, can be found in the Program Documentation section of this website.
