The implementation of the packedCoordinate sequence does not do any
dimension checking on the ordinate argument. Therefore if you say have a
2D coordinate sequence and request the 3 ordinate (z) then you will
actually be returned the value for the x value of the next coordinate.
The implementation to be safe should be something like.
public double getOrdinate(int index, int ordinate) {
if (ordinate > dimension) {
return Double.NaN;
} else {
return coords[index * dimension + ordinate];
}
}
