Importing .bag (bathymetry) files into QGIS 3.x

Geographic Information Systems Asked on August 2, 2021

I downloaded bathymetric data from the NOAA Bathymetric Data Viewer website: https://maps.ngdc.noaa.gov/viewers/bathymetry/

I’ve tried to import and view several .bag files from this website within QGIS with no luck. I have tried versions 3.10, 3.12, and 3.14. The files I tried to view were downloaded from: https://www.ngdc.noaa.gov/nos/H12001-H14000/H12053.html

I was able to import and view these files just fine in QGIS on a Mac. I, however, wasn’t able to on a PC with a Windows 10 OS. I read some github forums where this seems to be a Windows issue: https://github.com/OSGeo/gdal/issues/1428

I was wondering if anyone knew a workaround to import the .bag data into QGIS to either fix the gdal issue if it is one or import the data using the python console, etc.

Here is what I see in QGIS:

It loads up the data in the correct geographic loaction and lets me change the symbology but nothing is viewable.
