Hi Christy, 

Depending on whether you are after the vector to raster functionality of
TOPOGRID or the DEM processing functionality, both can be accomplished with
an ArcView 9.x license. 

-	To convert contour polylines and spot points to a raster DEM, you
will probably need to use a Spatial Analyst tools and license with ArcView.
There are a few workarounds to this- try ET Geowizards (You will have to
build a TIN first then you can make a raster DEM from the TIN).

-	For processing the DEM, there are a few options. The first would be
the latest ArcHydro tools from the ESRI water resources team available from
the GISWR Consortium (http://www.crwr.utexas.edu/giswr/). You will
definitely need a Spatial Analyst license for these tools. Another option is
TauDEM from David Tarboton at Utah State University. His extensions are
available for ArcView and also MapWindow which has a GNU license
(http://hydrology.neng.usu.edu/taudem/).

Hope this was helpful. Good luck.

Good morning!
 
Does anyone know if topogrid or a similar utility is available with an
ArcView 9.1 license?
 
Thank you,
Christy
