i'm trying to model some tree crowns in in eCognition Developer 9. I already do have some objects which are more or less of a circular shape but slightly irregular (because of overlapping in the canopy).

Is there a way to calculate the maximum (based on on the "largest extent") diameters of each of these objects?

Because i think it would be closer to the real diameter which is why i'm not simply using the area attribute for calculation.

    Are you committed to staying within eCognition, or are you willing to use ArcGIS to find the polygon diameter? – Aaron Dec 13 '14 at 18:07

    Thanks for your replay. I thought about using the Minimum Bounding Geometry tool in ArcGIS (resources.arcgis.com/en/help/main/10.1/index.html#//…) as well. But finding the maximum diameter in eCognition would save a lot of im- and exporting. Plus i could use it in my classification process, so i would prefer staying with eCognition if possible. – Charnel Dec 13 '14 at 19:03
  • Thanks for the clarification. I will be staying tuned as I also have been looking for a way to do this entirely in eCognition. – Aaron Dec 13 '14 at 19:36
  • What is wrong with the 'Width' and 'Length' parameters in eCog? – Mikkel Lydholm Rasmussen Aug 22 at 9:15
