Hi all,
I have an ECW file, see gdal info below. I need to reproject this into
EPSG:900913 or EPSG:3857
Do I need a key to make the output file ECW?
The performance vs size when zooming out is impressive with ECW, but it
does not look like I have ability to create ECW. Are there better

If you use SDK 4.x, yes. With SDK 3.X if the image was < 500 MB, you

Second problem, when I try to convert it to a tif it always dies like

JPEG2000 or MrSID are somewhat similar to ECW.

Thanks Jukka, very informative. I'll start with jpeg compressed tiffs
and will do additional tests next year. I'm on a Cloud environment
nowadays, so it's easy to set up clean VMs for testing. Any suggestions
for experiments with different raster formats would be very welcome.
