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

Hi all, I am investigating Nearest neighbor algorithm of gdal_grid. The search ellipse is described by the three parameters: radius1, radius2, angle . My target is to get a regular grid as similar as possible at the original cloud of point, with the same values (no interpolation, so I choose the
