Digital surface model (MNS)

An accurate representation of the relief is essential for a large number of land management applications. Digital terrain models (DTM) and digital surface models (MNS) are simplified representations of ground altimetry.

The MNT is a representation of the altitude of “bare ground” without infrastructure, while the MNS reproduces the shape of the Earth's surface by including all the permanent and visible elements of the landscape such as the ground and buildings.

It is possible to add vegetation by including the [Numerical Canopy Model (MNC)] (/city-of-montreal/model-numerique-de-canopee-mnc).This third party metadata element was translated using an automated translation tool (Amazon Translate).
