  abstract =     "Transformation of coordinates usually invokes
                 levelwise processes wherein several sets of complicated
                 equations are calculated. Unfortunately, the accuracy
                 may be corrupted due to the accumulation of inevitable
                 errors between the transformation processes. This
                 letter rephrases the transformation of coordinates from
                 global positioning system (GPS) signals to 2-D
                 coordinates as a regression problem that derives target
                 coordinates from the inputs of GPS signals directly. In
                 this letter, a genetic-based solution is proposed and
                 implemented by the techniques of symbolic regression
                 and genetic programming. Since coordinates for a GPS
                 application are obtained by using simpler
                 transformation formulas, the computational costs and
                 inaccuracy can be reduced. The proposed method,
                 although it does not exclude systematic errors due to
                 the imperfection on defining the reference ellipsoid
                 and the reliability of GPS receivers, effectively
                 reduces statistical errors when accurate Cartesian
                 coordinates are known from independent sources. To our
                 best knowledge, this letter is the first attempt to use
                 genetic-based methods in coordinate transformation for
                 GPS positioning. From the experimental results where
                 the target datums TWD67 and TWD97 are investigated, it
                 seems that the proposed method can serve as a direct
                 and feasible solution to the transformation of GPS
