xyz2grd

Hi,

I am using xyz2grd to convert the text file into grid file as follows:


xyz2grd Perugravity.txt -R-78/-66/-20/-9 -I1k -GPerugravity.grd -V


and then trying to get image of the grid file:


system "grdimage -Y2i Perugravity.grd $rflag $jflag $bflag -C$cptfn2  -V -K > $psfn\n";


Instead of getting a smooth grid surface of bouguer anomaly for the Peru region, I am getting image with discrete branching like course of river distributed all over. I have attached both the text file and the image of the grid. I would extremely grateful for any suggestion.


Thanks
