[1]
This is a* trivially small array: 2.34MB*
Array size is *NOT* the issue.
==================================
ncl 0> f = addfile("*IGBPa_1198.map.nc <http://IGBPa_1198.map.nc>*","r")
ncl 1> class = f->CLASS
ncl 2> printVarSummary(class)

Variable: class
Type: *byte*
Total Size: *2332800 bytes*
            *2332800* values
=================================

The vegland_1.ncl script at
*http://www.ncl.ucar.edu/Applications/classification.shtm*
<http://www.ncl.ucar.edu/Applications/classification.shtm>l
works just fine. It yields the exact figures shown in the example.
====================================
[3]
Offline you sent me: *"When I turn off the "RasterFill" ..."*
When you did this you are *no longer running the vegland_1.ncl script.* You
are using a modified script. This should have been mentioned in your
original email.
=====================================
[4]
When you 'turned off RasterFill', NCL defaulted to using contouring.
Contouring should not be used with categorical data [CD]. CD are NOT
smoothly varying. A grid point with value 18 could have value 2 next to it.
This results in MANY
contour lines being drawn.
Hence" "*fatal:ContourPlotDraw*: Workspace reallocation would exceed
maximum size 100000000"
