Example of a map projection. The observation (3 × 3 raster footprints) is shown with color symbols. The squares show the spaxel center (5 × 5 spaxels for one raster position), the large diamond shows the spaxels (1, 1), and the dots show the center of the subspaxel (1 / 3 of the size of a spaxel). The information from different spaxels and rasters can be combined to populate the projected grid. Subpixels where there is no coverage are shown as gray squares.
