Re: [gdal-dev] gdal_grid: how to choose ellipse radius

Thanks Even, is the radius1 and radius2 unit in pixel? Because my grid size is: cloud coverage [km] / cloud resolution [km] so the pixel resolution of the grid is 1 pixel. Is this the right value to assign to radius1 and radius2? Should it be always an integer value? I think that setting radius1

I think you're right Frank. It may take me some time to figure out how to get it working correctly. Your message did remind me of one HUGE change that Apple made between the beta versions of their Xcode IDE and the final production version: 64 bit support for the new iPhone 5S. (
