[postgis-users] importing 3d shapefiles

[Ivan Kautter]

Mark,

Just out of curiosity, what was the specific shp2pgsql statement that you 
used and how were you able to confirm that the imported line is only 2d and 
not 3d.

Also I am curious if you can confirm that a 3d shapefile was indeed output 
from GRASS.  I am assuming you used v.out.ogr and specified it with layer 
creation option ARCZ.

Having no experience with these issues, I can't suggest a course of action, 
but it might be good to confirm for those who can assist you the steps that 
you took to create and import the 3d shapefile.
