In Germany, more and more state agencies allow free access to high resolution elevation models. However, these are often released as xyz tables, which are not easily used in GIS environments. A standard method to convert this format to raster formats (eg. GeoTiff) is the GDAL function gdal_translate [1, 2]. However, converting 1M lines takes dozens of seconds and is not trivial to parallize.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
