Re: [gdal-dev] sqlite dialect: OpenFileGDB and FID Column selection

Hi, When the SQLite dialect is used, a temporary SQLite database is created. OBJECTID is a feature identifier (FID) and I guess that the FID gets converted into a primary key with the SQLite defaults. So maybe you can find the OBJECTID from ROWID. I made a simple test and at least this command

Re: [gdal-dev] Universal raster to rgba?

Hi Javier, thanks for the detailed breakdown. I had a sense of some of those cases but didn't know all. Still, I think there is a use case, like for users of my program, where they have a file that covers a certain region, and they prefer to see *something* rather than nothing. I imagine a func
