 With the OSGeo LiveDVD, disk space is a premium. There has been reports
 from the LiveDVD mailing list about the relatively high disk space being
 used by MapGuide. The bulk of this bloat is the CS-Map coordinate system
 dictionaries.

 I recently asked the question about slimming down the CS-Map distribution
 and got this response from Norm Olsen:

 {{{
 Hello Jackie . . .



 If trimming the size of the distribution is the big issue, please consider
 the following:

 To the best of my knowledge, MapGuide does not ever use any of the Geoid
 Height functions within CS-MAP.  Thus, all of the data files in the three
 Geoid sub-directories of the Dictionaries/USA directory can be omitted
 from the distribution.  Also, the WW15MGH.GRD file can be removed from the
 Dictionaries directory.   Much of this data is in binary form and does not
 compress down very well, so the distribution size reduction could be
 significant.



 Norm
 }}}

 For reference, that's these directories:

  * CS-Map/Dictionaries/Usa/Geoid03
  * CS-Map/Dictionaries/Usa/Geoid96
  * CS-Map/Dictionaries/Usa/Geoid99

 And these files:

  * CS-Map/Dictionaries/WW15MGH.GRD

 Creating a size-optimized version of the linux build scripts that omits
 these directories and files will save up to 116mb on the LiveDVD.

 If we are only going to showcase the Sheboygan dataset, this omission has
 no negative effects and in fact we could even probably cut out more CS-Map
 dictionary files and save even more space on the LiveDVD.
