So far no real or major problems have been reported. Also, note the bug fix below:

1. Wrong scaling for GTOPO30
   Somehow, a '-S1' option got lost in the img2latlongrd line that iGMT uses to plot the Smith & Sandwell GTOPO30 topography data set. This results in usage of the default scaling factor (0.1) so that all heights are too low by a factor of 10.
   Fix:
   Change line 500 of igmt_plotting.tcl
   

   
        set nrs [ add_to_script  $nrs gmtstring "$img2latlongrd $gtopodata  $inc \$region
   -G\$grid_filename -T1" ]
   

   
   to
   

   
        set nrs [ add_to_script  $nrs gmtstring "$img2latlongrd $gtopodata  $inc \$region
   -G\$grid_filename -T1 -S1" ]
   

   
   (Note the addition of '-S1' at the end of the line.) You can also download a modified version of igmt_plotting.tcl for iGMT1.0.
