Overviews are not generated in this case (see COG driver high level details) 🙂
Overviews until the maximum dimension of the smallest overview level is lower than 512 pixels.
Here is the gdalinfo
output of a file I generated earlier:

Ah perfect, great that the driver has this built in by default.
The recently added annotation layer 'wind-modeled backscatter' (#138) will now be correctly formatted using the
COG
driver, with LERC compression (2e-5
error threshold) and the same nodata value as other float32 GeoTIFF layers (-9999.0
).
