Something like the following perhaps? gdal_translate -projwin 0 90 180 -90 g0-360.tif g0-180.tif gdal_translate -projwin 180 90 360 -90 -a_ullr -180 90 0 -90 g0-360.tif g-180-0.tif gdal_merge[.py] -o g-180-180.tif g0-180.tif g-180-0.tif

However, I would rather they be in the -180 to 180 degree range. While I can do this converting into VRTs and playing around with the SimpleSource element, I also saw a posting on this list that suggests that one can easily use gdalwarp for this <http://lists.osgeo.org/pipermail/gdal-dev/2006-June/009293.html>. The suggested command is gdalwarp --config CENTER_LONG 180 openev/utm.tif ll.tif -t_srs WGS84 I have tried this command on my file (which is initially in WGS84 0 to 360), set the value of CENTER_LONG to 0, but I basically get my old raster back, with the longitudes going from 0 to 360. Anything other than scripting/VRT editing? Thanks! Jose ------ If you have received this transmission in error please notify us immediately by return e-mail and delete all copies.
