Thank you! That's exactly what I've been trying to figure out!

comment ArcMAP path distance function handling of polygon and raster inputs
In the example on that page they're not using polygon inputs - if they are they're the exact same size as the analysis cell size. I want to know what happens when the polygons span across multiple pixels

comment ArcMAP path distance function handling of polygon and raster inputs
I had been through those examples before. However, while they show a general example using polygons as input in the path functions and the line the actual path drawn by the program, I haven't been able to find anything explaining what happens in the cost raster generated by the tool. In this case I'm interested in the distance raster, not just the least cost path.

comment How do I create groups of points from lat/long pairs?
Also, I've found the YaRi tutorial helpful for R: ahandel.myweb.uga.edu/resources.htm

comment summing up over an area based on a distance related function
You can calculate distances using polygons. But you would still need some kind of spatial structure within the polygon to store the information in. How do you need to present or store the distance data once you have it calculated? This may change the tool that would be best.

Sorry. Globcover or one of the usgs datasets. They seem to be working on similar problems.
