I am working with a google map on which I want to attach a grid of five points. Only one of them has real coordinates in the centre, point O ( 8.32688E, 48,32933N). For all the rest only the excel coordinates with respect to this know central point. I want to plot the grid on the map and also I want to determine properly the coordinates of the other 4 points. I quite appreciate any help on this respect.
