Hi Ana,
Raster - is a term the usually means image or digital photographs.   
Vector - is a way of drawing shapes, like line or polygons or even  
just individual points.  Your TIFF files are a type of raster data.   
I don't have GRASS handy, but you will need to use a raster import  
function.

There are some global datasets that likely cover your country (what  
country is it?).  Tell us more and maybe someone else on this mailing  
list will have your answer.

Good luck,
Tyler
