Dear GrADS users,
I need your help with this problem.
I have two-dimensional data, which have no linear resolution, such below;
1. The first, second, third and the last coordinate longitude data are
21.2887, 121.29860, 121.30840 and 148.76140, respectively.
2. The first, second, third and the last coordinate latitude data are
22.70906, 22.70909, 22.70911 and
I want to make the control file for the data to plot it by grads,
XDEF LEVEL 2800 121.28870 XXXX
YDEF LEVEL 2400 22.70906 YYYY
What number should I use to change XXXX and YYYY?
and is there special command should I use to handle the irregular spatial
Very appreciate for your help.
Thank you very much.
