[mapserver-users] Converting PDF files to GeoTiff

[Schweitzer, Peter]

You're working with the USGS historic topo map collection.  In the
long run it might be helpful to communicate to the appropriate office
of USGS your need for these to be provided directly in GeoTiff rather
than in GeoPDF.  I'm sure that our people discussed the format issue
and came to their current decision based on many factors, including
the demand they foresaw for specific formats.  But if there is a much
larger demand for GeoTiff than they had anticipated, I imagine that
might enable them to revisit the decision.  Of course the conversion
would entail a cost, but if the number of realistic users is large
enough, it would seem efficient to do this conversion once for
everyone rather than separately by each user.  The key issue, I
suspect, is balancing the number of people who would benefit against
the cost of creating and maintaining an accessible archive of
converted GeoPDFs.  But the information needed by the current
maintainers is the extent of the demand.  This is just my opinion, and
I'm in no position to promise anything, but I do encourage you to
communicate your needs to the current maintainers.

The converted files work fine with the OpenJPEG drive, but the size almost doubles and on my 10 year old pc at home it takes about 3 minutes per file to convert.  I will look at all the options you mentioned below.
