Situation:
1. Have 2 ASCII data files. x, y, and z coordinates.
2. One file contains nearshore data and the other
contains offshore data.
Goal:
1. Combine data to make a raster map of combined data.
Have tried:
1. s.in.ascii and s.surf.tps under no tension
When nearshore and offshore is done seperately,
the contours come out looking good.
2. Tried combining and the offshore plays havic on
the onshore.
Can you do the two maps separately, and use a mask layer based on
the shoreline to zero out the parts of each map that don't count,
then simply add the two maps together? I am assuming "nearshore"
means on "land", and that the discontinuity is the actual shoreline.
Working with mask as suggested by Martin worked very well for me
when I needed a discontinuity (or fault) along a given line.
(you can define the mask as an option when running s.surf.tps)
We are developing some other approaches to problems involving
modeling the surfaces with abrupt changes
so I would like to ask the original sender of the message if he can
contact me, define more accuratelly his problems and give us a
sample of his data, if possible.
Thank you in advance,

P.S. This sounds sort of embarassing but I don't understand what do
you mean by "the offshore plays havic on the onshore" so in fact,
I did not know what to answer. It also was not quite clear to me
what was meant by "s.surf.tps under no tension".
