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.

Hi Mike,
I have GM 15. If you send me a couple of your .PDFs I could benchmark
converting them with GM. GM is good at tiling, if you want the output
broken up, or put in a pyramid.

Subject: Converting PDF files to GeoTiff
On a perhaps related subject, I was wondering if there was a preferred way
to convert PDF map files to georeferenced GeoTiffs? I have thousands (many
thousands) of these to convert.
The tools I would like to use in order of preference are:
Perl
QGIS
Any open source software
Global Mapper
I am on Win7.
Here is an example of a file I want to convert:

I am also not adverse to downloading the entire country (USA) of GeoTiff 15
minute topos if they exist somewhere, but I have not found a location that
serves them up for free.

Hi Jukka,
I have Global Mapper, and used it to do a batch convert to geotiff on a
test set of images. 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.
Thanks!
James
