Definitely, it is a defect in QGIS srs.db. I have posted a scr

I agree 100%. I'm not pleading for on-the-fly projection at all. However,
since I'm currently teaching a training course which also includes QGIS
and gvSIG, I also use that feature, but apparently I'd better not !
agreed: same experience for me, here in Evora.

no, they don't. LL WGS84 is just that (as long as we consider it the root
coordinate system), and 31370 explicitly gives 7 term +towgs84= p

Thanks to everyone for their answers. I've tried all the different
suggestions and the answer seems to be clear: on-the-fly projection does
not work properly in QGIS and gvSIG... Whatever I do in GRASS, I always
get correct placement of the GPS data.

Hi all,
In settings -> options -> projection, try to set "prompt for projection" and
select the desired projection (define a custum one, if you prefer) every
time you import points (or whatever) using gpsbabel. Probably you set to use
a projection (different from the one defined with gpsbabel) as

Hello,
I'm trying to figure out why we are seeing different results when

the others that are having the trouble). It must be linked to the
