Hi, >> >> First : attached are the maps I obtain with the grdvector options -Si150 and -Si300, respectively : the second one (-Mercator2, with -Si300) shows two unexpected yellow lines, which I suppose to be head vectors inordinately stretched (?) >> > I see the 360 wrap around problem; will have a look.

If I give something not a multiple of one, e.g. 7.5, then I get the expected message: > grdvector: Error: New y grid spacing (7.5) is not a multiple of actual grid spacing (1) > > Are you sure you updated to the latest revision (r12527 as of right now)?

Using -I15, my error message says : "New y grid spacing (14.5) is not a multiple of actual grid spacing (1) » And the problem appears for other multiples of one (I’ve tried 10, 15, 20, 25…) The script is attached below, but I don’t see any difference with your command.
