[Gdal-dev] Tool to convert shapefile from [-180, 180] to [0, 360] range

[Christopher Condit]

Hi Daniel,
This is not particularly elegant, but here's a script I use to go the
other way (0 to 360 -> -180 to 180).  Just switch it and change the
values to match your files...

%gdaltx% -ot Float32 -srcwin 0 0 360 330 -a_ullr 0 89.250 180 -75.25
source.tif right.tif
%gdaltx% -ot Float32 -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

Good luck,

Chris

Is anyone aware of a tool or script that would convert the longitude of 
coordinates in a shapefile from [-180,180] to [0,360]? The tool could be

based on OGR or any other open source package.

Just checking before writing something from scratch and reinventing the 
wheel.
