Linux build scripts size-optimized for OSGeo LiveDVD

[jng]

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.

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.

r8134 produces a coordsys-lite package which we should use if integrating into the live dvd.
