> Another question. Now cgvector work fine with cgmap object, but not with cgmapset. Very thanks!

In what way do you think it doesn't work?

This works:

posx = cgScaleVector(RandomU(seed,200), -160, 160)
posy = cgScaleVector(RandomU(seed,200), -35, 70)
velx = RandomU(seed,200)-0.5
vely = RandomU(seed,200)-0.5
cgMap_Set, /Cylindrical
cgDrawVectors, velx, vely, posx, posy, /Overplot, VecColor='red'
cgMap_Grid
cgMap_Continents

Cheers,

David
