Hi all,

I am trying to re-project a very large image (size 40,000 by 40,000 pixels,
resolution ~120m) located at high latitudes (60N) to a standard wgs84. By
searching some previous posts, I come up with the following command:

gdalwarp  -of EHdr -t_srs EPSG:4326 -tr 0.001111 0.001111 --config
GDAL_CACHEMAX 200 -wm 200 -wo SKIP_NOSOURCE=YES -r bilinear -multi
input_ice.tif output_ice.tif

it is working now but the speed is very slow - likely this will take 12
hours... Any way to speed up or am I wrong in selecting the parameters? Many
thanks.

Kevin
