I have a large set of imagery that I created a mosaic from in arcmap 10.1. I want to use GDAL to create the overviews because arcmap has issues building the pyramids and never seems to complete. I have experimented with using the GDAL command line utilities specifically:
gdaladdo image.png 2 4The image alone is about 4gb. When creating the overviews using the above command, it generated and overview file over 60 gb in size.
So my questions are:
What levels should I include in the command to mimic what arcmap would create by default?
What else can I do to reduce overview size?
