Hi all,
I'm using gdal 1.7.2 and still have the problem of reprojection with
data crossing 180W/180E.
The data are in lat-long from:
http://www.naturalearthdata.com/downloads/50m-raster-data/50m-shaded-relief/
The image is then cropped as follow:
gdal_merge.py -ul_lr
-180.0 -50.0 180.0 -90.0 -of GTiff -o SR_50_crop.tif SR_50M.tif
and projected in polar stereographic as follow:
gdalwarp -s_srs EPSG:4326
-t_srs EPSG:3031 -of GTiff SR_50M_crop.tif SR_50_stereo.tif
In the reprojected image, a sector of data is missing around the
180W/180E meridan. This sector is several degree wide although the
original data was with a resolution of 1/3 degree... surprising.
Is it a bug ? or something wrong with my gdal commands ?
Cheers,
Ghislain
