I.4.6.8 “modifyPositionRefCoordSys” method

“modifyPositionRefCoordSys” method is used to modify the reference coordinate system wrt which vectorial Results corresponding to coordinates are expressed. The Results must be vectorial.

The method returns nil (no new Result object is created) and takes two arguments:

1.

A DataBase object.

2.

An integer object corresponding to the index of the coordinate system to which one switches. This index must be larger than or equal to 0 and defined in the DataBase argument. One can also provide a CoordSys object instead of the integer argument.

For the reason of the presence of the DataBase argument, see section I.4.6.7.

This method can be used with real Results only and returns the modified “Result” object.
