[GRASS-user] Creating dem using a contour map.

[Moskovitz, Bob]

Hello list,  
 
I have a 20 foot contour map shapefile that has over 47000 line strings.  Many of these lines have gaps (see   <http://picasaweb.google.com/bobdebm/Problems/photo#5133539789447176242> http://picasaweb.google.com/bobdebm/Problems/photo#5133539789447176242)   in many of the contour lines.  I want to use v.surf.rst to make a dem.  Will I have problems using this file? 
 
Thanks, 
Bob
