Hi,

I have a raster (a rectangle). I want to shift it through giving the four corners new coordinates.

Could anyone help,
Thanks

but why would you want to specify the four corners?

Thanks,

actually the problem is more complicated than shifting a raster.
I am working with data sets from a climatological software (called COSMO) and imported these netcdf files into the ArcGIS. Now these files are based on a rotated coordination system, and not on a the real geographical system.

When I plot the country of interest - which should be in the middle of the domain I get its data as netcdf files from COSMO - the country is away from the domain. This is logic, because the country has the real geographical coordination system.

I wanted to shift the country to be in its (rotated) coordination system and to match the netcdf-based domain. This is correct but very inaccurate. Why? because all the x&y coordinates of the country should be transformed into the rotated coordination system. There is a FORTRAN script I wrote to transform these points. But the question now is:

*** How to get the whole x and y coordinate of a certain polygon, a country?

Thanks
