I need to solve this using ArcGIS:

 

I have a collection of polygons (irregulary shaped), each with an attribute X (an integer). I need to split those polygons into X parts. Would be nice if those parts are more or less equal area but that's not necessary.

 

I know this is possible in FME (because I've done so many years ago, just can't find that workspace anymore) but the thing is I'm doing this for a customer who only has ArcGIS 10.0

 

Any suggestions? I've looked at the Jenness tools but that's not quite what I'm after. Looked at the new GME (formerly Hawths Tools) but didn't see anything there that immediately popped out.

Hello Hans,

 

You could still use FME if your data (polygons) an be converted to SHP file, the output can be SHP shouldwork with ARCgis.

Another soft is Globalmapper, I mainly used it for slicing raster into smaller pieces by a grid which can be defined in Global Mapper.

I still have 13 days available for my FME 2014 Trial, I could help you out with a workbench if needed.

Thanks, but I'd really like to do this within ArcGIS (because that's what my customer uses)

Yeah, I found those as well, but the problem is that they all seem to work on a one-by-one basis, so one feature at a time. Not very useful if you need to process hundreds of polygons this way.

it says that the Split Polygons command allows you to split many polygons simultaneously, yet you need to have overlapping features to split.

The idea that I had in FME was to generate Voronoi polygons from a collection of points (either the original points that would have to be overlayed with the polygons to find out how many chunks I need to make or random ones) and then clip those with the original polygons.

 

To give a sample of what I want to do, say I have buildings with multiple addresses per building, like an appartment complex. I want to generate one little polygon per address by cutting up the original building polygon.

Did you ever figure out a solution for this using ArcGIS?

Nope. I tried the Voronoi idea in FME which worked kinda ok-ish (if it wasn't for the fact some of those address points were actually outside the buildings... yeah, if your data isn't cleaned up your options suddenly diminish quite a bit)
