I am now working on some irregulately-spaced data.
Recently I used the trigrid to get the spherical gridding of my data,
but I found the keyword 'max_value' would not work at all. The
corresponding Z value of my data are most less than 0.1 except those bad
data which is given an value ' 1.0E+12 '. But whatever I set the
max_value, the result of the trigrid would not change, which were always
some values that much greater than 0.1 . This is obviosly effected by
the bad data. So I doubt the max_value is working or not. The second
problem is that my data are all positive values, but after doing the
spherical gridding, there are a lot of negative values for the nodes of
the grids. I am afraid they are not doing the right work. Do you have
the same problem? How do you get over them? Any suggestions to :
