s.surf.tps in lat/long coordinates

[KLENKUS1 at VAXC.STEVENS-TECH.EDU]

I have a file of concentrations of a substance and the
distance (DMIN) .0032 degrees.  My file says the
distance is too concentrated.  

Is this a general problem with lat/lon?
My current solution was to multiply by 1000 and import it
into a xy coordinate system.

Has anyone seen this problem before?  Any other solutions
then the one I have implemented would be appreciated
