We developed metrics to examine theoretical and empirical radii as well as bias in edge length in geographic networks. The empirical case in this study involved personal networks involving help/support after Hurricane Katrina.

prediction with social and spatial proximity"

online social networks"
We have also an upcoming paper to be presented at ICWSM 2011:
"Socio-spatial Properties of Online Location-based Social Networks".
It's not available online yet, but I have a link on my webpage.
Good luck with your research.
