Hi Ken, This topic is really an continuation of your earlier post about extension-less source data, I'll assume you've read my reply to the earlier message in this reply.
My hope with the code in vpb::System::System that queries supported GDAL's file extensions was that it'd catch all supported formats, but if the list isn't complete then this may well be a GDAL bug/incompleteness. Since users will use VPB against a range of different versions of GDAL then I'd suggest we add the missing ones into the System::System header to catch them. Perhaps one thing we could do is when we read a source file we check against the supported extension list, if it matches then accept the source file, if it doesn't match then check a black list of unsupported extensions, if it matches then reject it, else check the file by trying to load it with GDAL then if it succeeds accept it, and add the extension to the white list, if it fails add it to the black list. Such as scheme should allow us to steadily build up the list of supported/unsupported files. Robert.
