I've looked at the patch and it seems good. I'm not sure I would have added a new column in the table, but if you think it is usefull, keep it. It would perhaps be good to mention in gdal_datamodel.dox, in the SUBDATASETS section, that drivers that support them advertize the DMD_SUBDATASETS capability. And I think that swig/include/gdalconst.i should also be edited to add the new constant. After that please commit. I'm not sure it is appropriate to backport in 1.9 however (new feature, output of gdalinfo --format modified). 1.10 should be out soon hopefully. > > Regards, > Etienne > > On Tue, Nov 20, 2012 at 10:43 AM, Etienne Tourigny > <[email protected]> wrote: > > Hi > > > > I'd like to be able to identify which raster and vector formats > > support subdatasets (or multipl layers). > > > > A quick grep search (grep SUBDATASETS frmts/*/*.cpp) showed which GDAL > > drivers can report subdatasets. > > Am I missing something? > > > > I think it would be nice to include this info in the driver summary > > page - should I just edit the html or is there some other file to > > edit? > > > > I was wondering how to find that out for OGR drivers - or do all > > drivers support multiple layers in one datasource? > > > > > > Regards, > > Etienne > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev > _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
