''DEM stands for Digital Elevation Model. It can be represented as a regular grid of points or as a [[Triangular irregular network]] of points. DEMs are the basis for digitally produced relief maps.''

== Possible contents and links==
On second thought, it may not be inappropriate for categories
to contain a main article, like [http://en.wikipedia.org/wiki/Category:Geographic_information_systems here]!

From Liu & Mason 2010<ref>Liu, J. G. & Mason, P. Essential Image Processing and GIS for Remote Sensing. (John Wiley & Sons, 2010).</ref>:
DGM's are a subgroup of [[Surface models]] and can be obtained by
# [[Photogrammetry]]
# [[Laser altimetry]]
# [[SAR inferometry]]
