[gdal-dev] gdalwarp large imagery faster?

[GeoSpatial - Kevin]

Hi all,

I am trying to re-project a very large imagery (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 selecting those parameters?
Thanks.

Kevin
