Original Q:
I have a line shapefile of contour elevations. I have AV3.2 and
spatial analyst but not 3D analyst. I have Surfer. I want to create a
digital elevation model that can be displayed on the web. Can anyone
offer advice on the best way to do this, given the tools I currently
have to work with? I haven't figured out how to bring the shp file
info into surfer to create the 3D image.
Solution:
Some digging through the Surfer Support Forum archives led me to an
ArcView script called "surfer extension 2.6" at
http://arcscripts.esri.com/ (thanks Giancarlo Ciotoli for pointing
that out)
You have to first convert the contour lines to a grid using ArcView
Spatial Analyst. Then you "export data source" as ascii raster in
ArcView. Use the surfer extension to then convert the ascii file to a
surfer grid file.
Now I just have to read the surfer manual to see how to get the grid
to look like it is supposed to :)
