I do not know the reason why you created such a complex data strucxture for the points (@data), but i would start with making that simpler. 
@data = (
[
  [2289290.30567314, 507448.506452598],
  [2289282.72943502, 507410.155776398],
  [2289149, 507002.0625],
  [2289055.31527948, 506731.474946477],
],
[
[2289563.40820205, 512818.142015762],
[..., ...]
],
);

Or, you could use Math::Complex (see Genetic Algorithms in Perl) to use 2D points (vectors) and predefined functions for working with them.
