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

In info.grass.user you write:

s.surf.tps doesn't work with lat/lon yet, so your solution was
the right one.
In general s.surf.tps gives an error "Points are too concentrated"
when the smallest segment has only one row or column and cannot be divided
anymore while having more points that segmax. That is why
dmin=min(ns_res,ew_res) by default -- so that there are never more than
4 points per cell.
