Hello,

I have read a few articles in this forum and came acros the term "DEM" many times.

It stands for Digital Elevation Model (I believe) and is used as shorthand for the real world terrain data which it is possible to download from various sources such as the USGS. These lumps of data can be converted to bitmaps and then used as heightmaps in Vue and other software to re-create real world landscapes.
