Description
I'd like to be able to build pyramids for FAA GeoTIFFs like ENR_AKL01.tif found here: http://aeronav.faa.gov/enroute/11-08-2018/enr_akl01.zip
When I try, I get the "Building pyramid overviews is not supported on this type of raster" notification.
Basically, what I did was:
- Create a new project in QGIC 3.4.0
- Add a Raster Layer for ENR_AKL01.tif and allow the project CRS to be the same as the Raster Layer CRS; in this case "Generated CRS (+proj=lcc +lat_1=65 +lat_2=37 +lat_0=51 +lon_0=-154 +x_0=0 +y_0=0 +datum=NAD83 +units=m +no_defs).
- Save the project in the same directory as the source GeoTIFF (intending to avoid any write access/permissions problems)
- Try to build pyramids
Expected result is I can build them. :)
After some searching, I thought I saw (but couldn't re-find) that this perhaps is a problem with a rotated GeoTIFF?

It seems the raster has already some type of pyramids: if you use the tool in the Processing toolbox then you have the option to clean existing pyramids and new ones are created.
