Convolution-based gridding in the world coordinate system has the advantage that even relatively complicated tasks are easy to implement. In the visualized example an elliptical 2D-Gaussian gridding kernel with a bearing of 45° is used for a field close to the pole. Artificial point sources were inserted in intervals of 45° longitude at a latitude of 88.5°. The resulting ellipses in the pixel space are distorted from the chosen projection (zenith-equal-area) of the sphere onto a plane.
