Although this issue has been addressed in this post some months ago: Thiessen Polygon delineation within a Feature, the appropriate answer has not been given. So, new ideas are welcome. My question is how can we use the Create Thiessen Polygons (Analysis) tool available with ArcInfo license by defining an external feature boundary (e.g. study area boundaries defined by a polygon) for the created thiessen polygons. As I have seen this is not possible via the Environments...options in that tool. Is there any available code in VBA for doing this? or How can I run this tool within a VBA code? Thanks Demetris

EDIT

The comments indicate that ArcGIS 9.2 and 9.3 is being used, the tag indicates version 10, the first post is for that version not previous ones.

I was having issues in determining Thiessen/Voronoi polygons and the toolbox provided in the link gives the user the option to set the analysis extent in a variety of ways.. The implementation doesn't require an ArcInfo license.

EDIT

NOTE, the toolbox and associated script(s) are designed for ArcGIS 10.

The relevant link provides a python script. Because I have no idea about python since I am still working on VBA in 9.2 r 9.3 ArcView; how can I run a python script in these versions? Thanks –  Demetris Oct 6 '11 at 18:04
    
@Demetris I saw the arcgis-10.0 tag so I assumed that it was for that version. The reference provides a version 10 toolbox and associated scripts that allows one to do Thiessen/Voronoi analysis without an ArcInfo license. could you edit the tag and I will edit my thread to indicate the correct version number for ArcGIS –  Dan Patterson Oct 6 '11 at 18:30
    
I am sorry for that. I included tag 'ArcGIS 10.0' hoping to get a useful idea although I do not work on a ArcGIS 10.0. –  Demetris Oct 7 '11 at 4:43
