Digital Elevation Models (DEMs) represents a 3D surface model of a terrain. They are how computers store and display topographic maps that, before, were only possible with handmade contours and extensive calculations. DEMs are probably essential for every topic in earth sciences. Understanding the processes that governs the surface of the earth, with today's technology, usually goes through the process of manipulating a DEM at some point. Also, we need a DEM to mask out data over the surface in our resource models or maybe quickly check what's the height on top of Aconcágua.

DEM can be in form of rasters Triangulated Irregular Network (TIN).

In Python, recent modules and technics have made DEM rasters very simple to process and that's what we are going to integrate and explore in this post.

This is the PART 3 of a series of posts called Integrating & Exploring
