I would like to plot a grid over a map. I managed to do so as long as I
had a longitude latitude grid and could use gsn_csm_contour_map and
cnRasterModeOn = "True".
Now I have data in grid cells of 50km x 50km which should be plotted on a
stereographic projection (about all of Europe). In addition to the size
of the cells, I know the position of the northpole in coordinates of the
I guess, I have now to plot the contour (grid) and the map separately,
but on the same wks. My problem are now:
How do I fix the position of the grid-northpole to the map, even when
this is outside the viewport?
How do I determine the size of the map?
I hope I can get some hints or maybe somebody has an example. To make it
a bit more specific, here is picture how this should look like:
(And the definition of the map projection:
resources@mpProjection = "Stereographic" ; Change the map projection.
resources@mpCenterLonF = -30
resources@mpCenterLatF = 90
