[GRASS-user] export 3d vector line map to shp

[Markus Neteler]

Hi Martin,

I made a test and it seems to work!

GRASS 6.3.cvs (nc_spm_05):~> g.region rast=elevation -p
GRASS 6.3.cvs (nc_spm_05):~> r.contour elevation out=elev_contour_10m
step=10
GRASS 6.3.cvs (nc_spm_05):~> v.drape elev_contour_10m rast=elevation
out=elev_contour_10m3D

GRASS 6.3.cvs (nc_spm_05):~> v.out.ogr elev_contour_10m3D dsn=./
olay=elev_contour_10m3D lco=SHPT=ARCZ
Exporting 1008 points/lines...

GRASS 6.3.cvs (nc_spm_05):~> ogrinfo -so elev_contour_10m3D.shp
INFO: Open of `elev_contour_10m3D.shp'
      using driver `ESRI Shapefile' successful.
1: elev_contour_10m3D (3D Line String)

If I leave out the "lco=SHPT=ARCZ" part, a Line String (2D) is written.
