Exploring the possibilities to publish your maps and other content online
There are several ways you can publish or share your maps, created in QGIS, online. One very easy way is to use the Gisquick publishing platform. It basically requires two steps only; create a QGIS project, and upload it
The NASADEM_HGT dataset is a 1 arcsecond void-filled dataset which combines data from the SRTM and ASTER GDEM data. It can be downloaded from EarthData in 1° by 1° tiles. But if you are using GRASS GIS, downloading is greatly fascilitated using the r.in.nasadem addon. The addon imports all NASADEM tiles covering the current region or region extents given with the region option into GRASS and patches the tiles together.

Population density maps have multiple implications, e.g., to help relief agencies to better plan where they are needed most in case of disaster and in demographic, economic and environmental research.
Programs like R and GRASS GIS are incredible powerfull. But occasionally you'll need a functionality that is not available yet. Luckily, depending on the kind of functionality, it isn't terribly difficult to create your own scripts. In the past years I have created a few scripts that I hope are useful to others as well.
