[mapserver-users] Converting PDF files to GeoTiff

Thank you.  Give me some time and I'll post a few
of these maps.

I'll try GDAL.

I'm not sure if I want them tiled or not.  Whatever
makes the most sense.  Generally my GeoTiffs have the
border on them, so I guess that is my preference.

Execution time is not really a concern for me either.
I always have at least one computer running and doing
things like this.  I'm in no big hurry.

It would be nice if GDAL could do one map in under 3 minutes.
Lets see:  MO has 650.  650 * 48 = 31,200.
31,200 * 3 / 1440 = 65 days.  That should not be a problem.

I'll be surprised if the finished product is georeferenced.
If it is I'm really in business.


Mike
