Hi!
I imported 1°x1° data of Sri Lanka coverage, for seeing the complete map i used g.region and overlay. that's my result:

i tried to unite squares by using r.patch, but it works only for the central part...all but the upper square and the two lower ones; when i try to unite all squares i have problems...probably because "it miss 3 peaces". So i think to create 3 panels to "complete the rectangle", but i'm not able to do it...any ideas?
I also tryed to import a vector map of quite the same area, and to use it as a mask for create null values i deeded and at the same time to cut the dem, as i'll have to operate with both (vect and dem). So i had another problem: i can't import vector in the location...in particular if i use v.in.ogr from menu appears this error message:

ERROR: invalid ellipsoid i
  in file PROJ_INFO in PERMANENT
ERROR: invalid ellipsoid i
  in file PROJ_INFO in PERMANENT
    while executing
"exec -- $cmd --tcltk"
    (procedure "execute" line 4)
    invoked from within
"execute v.in.ogr "
    invoked from within
".#menubar.#menubar#file.#menubar#file#menu1.#menubar#file#menu1#menu2 invoke active"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke active]"
    (procedure "tk::MenuInvoke" line 50)
    invoked from within
"tk::MenuInvoke .#menubar.#menubar#file.#menubar#file#menu1.#menubar#file#menu1#menu2 1"
    (command bound to event)

if i use the terminal, i have:
GRASS 6.0.1 (elevation):~ > v.in.ogr
 in file PROJ_INFO in PERMANENT

Maybe i had to import a file called GeoTIFF? I referred to this guide:http://grass.itc.it/newsletter/GRASSNews_vol3.pdf 

Sorry if the message is so long and sorry for my english!!!

many thanks,
Antonio Giglio.

Ps: the .hgt files i used are: n05e080, n06e079, n06e080, n06e081, n07e079, n07e080, n07e081, n08e079, n08e080, n08e081, n09e079, n09e080.
