First of all you need to download the <a href="https://eoimages.gsfc.nasa.gov/images/imagerecords/57000/57752/land_shallow_topo_21600.tif">TIFF image</a> for <b>Blue Marble NG 2km</b> supplied by <b>NASA</b>
that actually is really huge image of about <b>173 MB</b>.<br><br>
That's not enough, because the TIFF supplied by NASA lacks any useful georeferencing information, so you need too a companion <b>WorldFile</b> that you can download from <a href="">here</a>.<br>
<b>Note</b>: both files <b>land_shallow_topo_21600.tif</b> and <b>land_shallow_topo_21600.tfw</b> must be placed on the same directory.<br><br>
Now you are finally ready for creating and initializing the <b>blue marble Raster Coverage</b>
