I am working with data from my boss who uses ArcGIS. I am aware that .aux files accompany raster files, but to my knowledge you can still use .aux files to create rasters in ArcGIS.
I'm working with limited data. Is there a way to use any of these files to create a visible raster in QGIS? I'm getting a visual when I upload the .aux file to QGIS, but it's only a black image. If I fiddle with the style it will disappear and turn into a white image.
Also, my companion was able to make the .sid file work in her QGIS, but she uses a PC and I use a MAC. Would there be any explanation for this?
