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 formats then GTif in the list below?


$ gdalwarp -t_srs EPSG:900913 -of GTiff -co TILED=YES -co COMPRESS=JPEG Saraji_South.ecw Saraji_South-900913.tif
Creating output file that is 34551P x 32332L.
Processing input file Saraji_South.ecw.
0...10...

This seems to be working, I suspect this will bulk up after I add overviews.

Thanks,
  -Steve
