How Much of the Different Drivers Are in the G Al Code Base?

Parsers are written in gdalt and poodle. Users can build a proprietary plug-in that will get woke up at run time to adapt the API to their driver. The majority of those are adaptations on the same thing, which is a bunch of binary bites laid down on disk with some meta data. You'll see things like j peg two thousand, an extremely complex specification for compressing raster data. And gdalt will just delegate and use that as the library writes. But you know, every company doing various things can make their own business choices or technical choices to do that.
