I need to load a BAG file (Bathymetry attributed grid) in QGIS (3.4) according to the supported file page https://www.gdal.org/formats_list.html it is supported, but is not compiled by default and requires "libhdf5" I have no idea what this means, is there a plugin I need to install or do I need to compile something my self? I have no programming experience, so compiling software myself is not an option.

Both QGIS 3.4.5 Long Term Release (LTR) and 3.6 can open BAG files from Data Source Manager -> Raster

In QGIS 3.6:

In QGIS 3.4.5 (LTR)

  • I did see this but get the following error when loading a BAG file. Invalid Layer : GDAL provider Cannot open GDAL dataset K:/4.Basemap Database/1.National/BAGS/Glencairn_0.5m.bag: `K:/4.Basemap Database/1.National/BAGS/Glencairn_0.5m.bag' not recognized as a supported file format. – Wilhelm van Zyl Mar 7 at 9:40
  • I think the problem is not in BAG files but in the path of your filenames. You have periods . in the bath after each number which is not acceptable. You need to change the . into underscore _ and see if the file can be opened. – ahmadhanb Mar 7 at 9:47
  • I copied the file to a local drive with no ".", got the same error. I did manage to load the raster by dragging the *.bag.ovr file into the project, but the .ovr is the overview as far as I know, and they do not plot spacially correct. This is the same for all bag files I have. They do load correctly in AcrMap. – Wilhelm van Zyl Mar 7 at 10:11
