What is a DEM layer in QGIS?

QGIS 3.0 comes with 3D layer view which enable us to visualize GIS data in 3D. So we can get a more vivid visualization of a data which contains elevation or height information such as Digital Elevation Model (DEM). DEM contains elevation information of earth’s terrain surface.

Is DEM raster layer?

A Digital Elevation Model, also known as a DEM, is a type of raster GIS layer. They are raster grids of the Earth’s surface referenced to the vertical datum—the surface of zero elevation to which heights are referred to by scientists, insurers, and geodesists.
