[GRASSLIST:5704] projection conversion

[Helmut Kudrnovsky]

hi GRASS-friends,

i´ve got a ascii-point-file from bird and amphibian watching measured in the Austrian Gauss-Krüger grid system (zone M31) based on the transverse mercator projection and the bessel ellipsoid:

43504.88195 326077.81792
44075.95816 324073.80644
44075.95816 324073.80644
44075.95816 324073.80644
44075.95816 324073.80644
43720.53742 324984.62938
43720.53742 324984.62938
43720.53742 324984.62938
....

i would need the points in a latitude-longitude format (geographic coordinate system). but i´m not sure about the procedure to get it:

1 - create a new location with epsg-code  31285 (MGI / M31)
2 – import the ascii-file with v.in.ascii
3 – create a new location with latitude-longitudinal coordinate system, the hermannskogel datum and the Datum Transformation Parameter 1 for Austria 
4 – projection conversion with v.proj
5 – export with v.out.ogr or v.out.ascii

is there may be a shorter way to do this?

with greetings from the snowy tyrol
helli
