[Gdal-dev] optimum overview settings?

[Chapman, Martin]

Matt, 

I don't think so.  I renamed an .rrd file to .ovr and then tried to open
it with gdal and it didn't work.  But, you could always dynamically
create them (.rrd) with ArcMap code.  See the attached files to build
rrd files from c++ in ArcMap 9.  You just need the arcobjects developer
kit to do it.  I think it is easily obtainable though, if you have
ArcMap.

Thanks for your insight Martin, it helps. :)

Are ESRI's pyramid files (.rrd) compatible with gdal's (.ovr)? It'd be
cool if I could generate pyramids from the command line for all 
our images at once rather than at first load time by ArcMap/Catalog.
