Re: Error while accessing RANGS, please respond

Dear Alberto,

Problem 1: the RANGS/GSHHS files should be stored in $NCARG_ROOT/lib/ncarg/database/rangs directory.

>> ls -la $NCARG_ROOT/lib/ncarg/database/rangs
total 275296

If you don't want to install the RANGS files in the recommended directory, you can set the environment variable
NCARG_RANGS to the directory containing the files.

Problem 2: You generate the contour plot before you have defined a colormap, so NCL will take the default
colormap.

To use the colormap with gsn_define_colormap move the call upward to the line below line 298.

   wks = gsn_open_wks(type,psoutfilename)
   gsn_define_colormap(wks,"WhViBlGrYeOrReWh")

Bye,
Karin
