sorry I dinot describe exactly.

I am working on a webservice which intend to handle data(mainly are the HDF4,) by grass,since the grass do not support the hdf,then I try to transfer the hdf4 to geotiff with gdal ,then import the tif to grass,the problem comes out ,should I create a new location and mapset for each geotiff each time??

ps:
If my current location is usa ,and I import a tif of china ,what can happen? If I should creat a new loaction but I have not seen the tif before and I donot know the location then how to do ?

you can find out, what the raster uses for coordinate system using
gdalinfo utility

you can also create new location according to the raster/vector map,
like

1) start grass in *any* location
2) run r.in.gdal location=NEW_LOCATION
3) switch to your new created NEW_LOCATION
