Hi,
For my MA degree I'm currently studying the defensibility of some archaeological hilltop sites. For this, I want to do Least Cost Path analyses from points in a circle around the sites in question to the sites at the centre. Although I know how to do a usual Cost Path analysis from point A->B, I can't figure out what I need to do in my case, so I have a few questions.
1) Is there a way to get ArcGIS to generate points at regular intervals along the edge of a circle? Or is it only possible to do this manually?
2) How can I adapt the ModelBuilder model to calculate Least Cost Paths from multiple/all points around a site to the site itself simultaneously? I heard it's possible, but couldn't think of a solution for it myself. I must be overlooking something. Do I just make the same model over and over again for each starting point and then run it, or is there a faster way?
Thank you very much for any help you can give me.
All the best,
Sander
