Hello, I’m getting trouble with grdvector use with GMT5.1.0 : I have two scripts with the same grdvector command to draw Nuvel-1 velocity vectors, one for a regional map, the other for a global map (attached). But the output maps look completely differents (see attached images) and I don’t undersand why. My grdvector command is, for both map : # add vector field vecsize=0.25+e+p0.25p velscale=i80 #Nuvel-1A gmt grdvector $rasterpath/plates/nuvel1.vy.1.5.grd $rasterpath/plates/nuvel1.vx.1.5.grd \ -T $region $projection -I30 -S$velscale -Q$vecsize \ -Wthick,black -Gorange --MAP_VECTOR_SHAPE=0.5 -O -K -V >> $carte where "$rasterpath/plates/nuvel1.vy.1.5.grd » is the Nuvel-1 velocity grid (x and y components). Only the -I option are changed (-I30 for the global map, -I5 for the regional one). How can the same script command gives so different results ?? Both scripts are also attached below.
