Hi all,

I received global radiation data with longitudes of 0-360.  I'm currently creating an ascii file to make a raster of the data, but have the following question for next step:  How does one convert this in Arc to -180 <> +180 deg?  Or maybe I don't need to?  I read somewhere that Arc will display the data just fine with 0-360, but won't run calcs on the raster...does that sound right?  Anyone have experience with this?

Cheers,
Cathy

Cathy,

Can you not deduct 180 of each of the values in excel or field calculator

Anthony - thank you - of course.  I'll try that!  Sometimes the simplest answers elude...
