How to perform the �??Create Thiessen Polygons�?� within the study area?

Please, see the attached image that shows my question

In ArcGIS, it is not easy all the time to perform some tools so that the output is bounded by a given study area, for example:

- If we need the output of the tool �??Create Tin�?� to be bounded by the study area then we set a boundary layer as �??Softclip�?� (see screenshot)
- Concerning the spatial analyst tools, we set the boundary layer to be the mask (see screenshot)

Then how to let the output of the tool �??�??Create Thiessen Polygons�?� bounded by certain study area?

Thank you in advance,

Regards

Jamal

An enhancement for this has been raised for a future release. For the time being, if you are talking about only one study area, you can run Clip tool to clip the Thiessen polygons by the study area polygon. If you have multiple study areas in the same feature class, you would need to do this one study area at a time in a loop (iteration).

Thank you Dan for the answer. that's great that this enhancement will be included in a future release.

Could you please elaborate more how can i make a loop (Iteration) so that i can perform this command (Create Thiessen Polygons) considering more than one study area?

appreciated

regards

Here is an earlier discussion on the same subject. Have a look:

Hope you can solve the problem using that solution.

Hi
I want to create Thiessen polygon within a watershed by using point data. I am using Arcgis 9.3 with all component. The problem is that, there is no '' Create Thiessen polygone'' tool in proximity function.
In proximity I just have Buffer and Multiple ring buffer. Do you know what's wrong with it? I am lost in the the middle of an assignment.

Best regards,

Perhaps you have the ArcView or ArcEditor license. You will need the ArcInfo license to get the Create Thiessen Polygons tool.

I have made with arcobjects if you haven't license arcinfo: https://github.com/nicogis/Voronoi
I intersect with envelope ( https://github.com/nicogis/Voronoi/blob/master/GeometryVoronoi.cs#L180 ) but you can change with your polygon (study area)

Jamal...after 6 months, could you close the thread by indicating that this was a correct solution (if it was) It saves the Moderators having to go around and clean up unclosed threads

Thanks Dan. Actually, I didn’t get my issue resolved here.

What I’m looking for is to get the output of “Create Thiessen Polygons” tool within the study area.
