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. James

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: http://www.mflan.com/temp/ny_west point_140214_1941_62500_geo.pdf 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.

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
