Re: opac polygon around a data field (rotated grid)

Hi Karin,

I take it the lines of the polygon are along constant lines of lat/lon? One thing that comes to mind is to programmatically generate samples at intermediate points along the lines of lat/lon, to approximate the curved lines. I haven't tried this (I don't have your dataset handy), but it should work.

Hope that helps…
Rick
