[Gdal-dev] shift coordinates with gdal

[Christopher Condit]

Hi Christian-
There was a discussion about this June last year. (see http://lists.maptools.org/pipermail/gdal-dev/2006-June/) and search for "Tool to convert shapefile".

To recap my response you could:
%gdaltx% -srcwin 0 0 360 330 -a_ullr 0 89.250 180 -75.25 source.tif right.tif
%gdaltx% -srcwin 360 0 360 330 -a_ullr -180 89.250 0 -75.25 source.tif left.tif
%gdalmg% -o correct.tif left.tif right.tif
%gdalinfo% -mm correct.tif

In my case the raster does not cover the entire globe, but you can put the correct values for your raster in the first two lines. Basically but the image into two files and then merge them.

Subject: [Gdal-dev] shift coordinates with gdal


hi list,
i have only a short user question concerning gdal: 
is it possible to shift a image with a certain amount, for example: i have satellite data with geographic coordinates from 0° to 360° longitude and i want them to shift to -180° to +180°. is there a chance to solve this problem with gdal or exists a workaround?
thanks and greetings from munich
christian
