Hello!

I'm trying to calculate fragmentation density.

The only method which I know is by the help of Spatial Analyst extension from ESRI ArcView.

From toolbox- Spatial Analyst Tools-Line Density.
But the result is not suitable for me (different result expected), because I'm doing something wrong somewhere (I've set the search radius to be 1 km).

Maybe a better opinion in a different software (open-source or commercial) is needed.

Thanks!

You might want to spend some time iteratively trying different combinations of Output cell size and Search radius. After a few tries you might get closer to your desired output.

I'm not too familiar with the software, but you might take a look at Fragstats.

Cheers,

OK!

Thanks a lot for the useful information.

I'll try some experiments.

You can also look into Patch Analyst, it was developed from Fragstats.
