I have a polygon feature class contains groups of adjacent polygons and the question is how to create a multipart polygon for each group of the adjacent polygons without dissolving it using python scripts.
thanks
All attributes should be assigned to the output multipart feature.
... and the common attributes need to be summed in some way or can you just to the attributes of the first part and assign it to the output multipart feature?
This task only for time and i do it rarely,
Not a in a workflow,
The manual method of doing this inappropriate as it dissolve them and i want each group of the adjacent polygons to be one feature one record as a multipart polygon but not dissolved,
There are common attributes between the adjacent polygons.
I didn't used a script so far, I am asking about it
You may also want to consider moving this thread to the Python place:
(see: What are Places? )
Might be best to dissolve the polygons not creating multiparts (yep the opposite of what you want) to a tmp featureclass and then loop through these features, select the original polygons, and add the polygons to parts of the new polygon to be created.
Is this a task that you are going to repeat multiple times?
Is it part of a workflow for something much larger?
Is it safe to assume that this is just a sample of a huge dataset making the manual method of doing this inappropriate?
Do you have anything within your attribute table that indicates adjacency?
Just need to know how far along you are in your script development. If you have some code you are working with, posting would be useful since people won't have to reinvent the wheel.
