AW: [GRASS-user] Project map

[Stefanie Obmann]

Hi!

I have another question concerning the projection of my vector layers.
I projected them by importing them from a mapset with geographic prj to a
mapset with lambert projection. V.out.ascii shows new coordinates which is
fine...

My question:
If I save my vector map as shp.-file for another GIS (ARCGIS in my case)
what projection does it use? My attribute table shows gg. Coordinates as in
GRASS. So do I have to project it another time?
(I also get a spatial reference alert back from the new GIS)

Thanks,

Steffi

Hi,

genau das macht ja v.proj... um die *Koordinaten* zu sehen:


GRASS 6.4.svn (lwd_lambert):/tmp > v.out.ascii HYD
189372.298871|389304.88446131|960|1
199811.87693732|399440.72876217|870|2
205231.53218899|392987.94788857|1295|3
186523.46925359|404389.42735205|1090|4
197282.90012946|409257.52605648|810|5
...

Problem geloest?
Bei Linien und Flaechen muss noch format=standard dazu.

v.db.select zeigt ja nur die Attribute, die natuerlich nicht beruehrt werden
von v.proj (auch wenn Koordinaten darunter sind).

Gruesse,
Markus
