[R-sig-Geo] location points that span UTM zones

[Corrie Curtice]

Hello,

I have some location data points that span two UTM zones.  I'm using
the points to estimate home ranges, using a couple of home range tools
(NNCH, HRT for ArcGIS).   Can I just project them to the left most
zone, and run the home range tools on that data set?  I'm curious to
know what the negative impacts of this might be.  These are points
around the west coast of Mexico, so UTM 12/13 and 13/14.

Thanks,

Corrie
