I'm using the File Geodatabase API reader to get data out of a file geodatabase. However, I get no results back. I've read in the manual that the File Geodatabase API supports only a couple of coordinate systems, and I'm guessing the one my data is in (EPSG:28992) is not one of them, because it works fine when I reproject the data to LL84 before loading it into the database. So... long story short, can anybody confirm my suspicion, or point me to a list of supported coordsys?
