OK. I'm not an expert on images, but I'd be interested in working with you. However, I avoid C++ like a lethal strain of the Swine Flu. :]
I may give some more thought to some of Bob's ideas about making it easier to work with image tiles. Thanks.

Gerlek Sent: Monday, August 24, 2009 3:19 PM To: OSGeo Discussions Subject: RE: [OSGeo-Discuss] Open File Formats and Proprietary Algorithms I've not given it much thought recently, to be honest. I'd need to review the current state of things in OpenJp2 (or whatever it's called) to see where they are at, what changes would be realistic and viable, how amenable they'd be to taking patches versus a fork, etc. Done properly, the work would have no "geo" specific component at all -- it would just be a new version of some of the internal algorithms. The test case would simply be to encode and decode an 500 GB(?) raw file on a box with 2 GB (?) of RAM. I would certainly not want anyone to have to build a whole new jp2 library from scratch, if that's what you meant. I'd really only be interested in C++ (or possibly mono-safe C#). -mpg -----Original Message----- From: discuss-boun...@lists.osgeo.org [mailto:discuss-boun...@lists.osgeo.org] On Behalf Of Landon Blake Sent: Monday, August 24, 2009 4:11 PM To: OSGeo Discussions Subject: RE: [OSGeo-Discuss] Open File Formats and Proprietary Algorithms MPG: When you say "effort" do you mean some sort of library to support JP2 geo side of things? What programming language would you be most interested in? C++?

Is this a project that should be shopped around for funding? Google Summer of Code? A grant from our ~benevolent overlord Google? Some other foundation or org interested in open data formats?

Not through lack of trying on my part :-) I think the two biggest reasons are: (1) The algorithms for handling large images in memory really are rocket science, and no one in the FOSS community has gotten the "itch" sufficiently bad enough to go and do the work needed inside the existing open source packages. Hopefully someday someone will. _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss Warning: Information provided via electronic media is not guaranteed against defects including translation and transmission errors.
