Hi, I have coordinates in KKJ3 and need to convert them into coordinates for Google Maps (and back). Therefore, I implemented the formulas from http://www.kolumbus.fi/eino.uikkanen/geodocsgb/ficoords.htm in code. WGS_84 convert(KKJ3 from) { double DX = -96.062; double DY = -82.428; double DZ = -121.754; double rx = -4.801; double ry = -0.345; double rz = +1.376; double m = +1.496;
WGS_84 wsg = new WGS_84(); wsg.X = DX + (1 + m / (10 ^ 6)) * (1 * from.X + rz * from.Y - ry * from.Z); wsg.Y = DY + (1 + m / (10 ^ 6)) * (-rz * from.X + 1 * from.Y + rx * from.Z); wsg.Z = DZ + (1 + m / (10 ^ 6)) * (ry * from.X - rx * from.Y + 1 * from.Z); return wsg; } Is this the right way to interpret the formula? I do not seem to get usable results out of it ...
