While I am still struggling to divide polygons into same sizes in ArcGIS (we are using ArcView 3.0 scripts now which work fine), I now have an even much more complicated problem:

I would like to split landcover polygons which surround a road polygon into equal sizes, while ALL resulting polygons should have access to the road!

Is there any chance to do this automatically? All programs, licenses etc. are welcome. I just don't have ANY idea how to solve this problem.

To make it more clear, I wanted to attache a basic sketch (but am not allowed due to lack of reputation).

Thanks so much for your input!

Can you upload sketch to an image sharing site? –  djq Sep 25 '12 at 14:52
    
Konrad you need a rep of +10 to post images on GIS SE. So someone else needs to up vote your question. –  Mapperz Sep 25 '12 at 15:05

Maybe he can post then link to the image and we can add it? –  R.K. Sep 25 '12 at 15:11

If you have an ArcEditor or ArcInfo license, you can use ArcGIS' Parcel Fabric tool.

In the parcel fabric, parcels can be divided by area to create new parcels. Using the parcel division tool, you can divide parcels using the following area-based division methods:

  • In equal widths
  • By proportional area
  • Into equal areas

I assume you want something like the image below?

Thanks R.K. for the reference to parcel division. I am aware of this function and tried it (altough its very complicated, I downloaded the 60 days trial version of ArcGIS advanced). The main problem is, that one can only specify the direction of division, but not further parameters such as the road access. Something like "all resulting polygons from division of Polygon A adjacent to Polygon B" Thanks for the additional Reps :) –  Konrad Sep 26 '12 at 8:55
