I have a raster set to 0-360E projected using WGS:1984.
When I modify the Data Frame Properties GCSWGS1984 to a custom meridian of 180, the raster does not move. The polygon of the continent moved but not the raster.
Also, I want the raster to display at 160. Because at 0-360, UK (of course) is cut lengthwise. So I want it at 160.
I am using ArcMap 10.3.
