It was suggested by the geophysicist Matteo Nicolli to change the colormap for a more perceptual option like viridis. save ( './data/processed/arrays/dem_array_hs', hillshade ( dem_array, 280, 25 )) UPDATE: save ( './data/processed/arrays/dem_array', dem_array ) np. seaborn for scientific graphs and geopandas that will be only used to import the area of study bounds.
The plt interface of matplotlib for plotting. We start by importing numpy for array creation and manipulation. I choose this specific area because of the presence of Geological, Geophysical and Geochemical data.

This is the PART 3 of a series of posts called Integrating & Exploring. 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. 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.ĭEM can be in form of rasters or, a vector-based Triangulated Irregular Network (TIN). 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. DEMs are probably essential for every topic in earth sciences. They are how computers store and display topographic maps that, before, were only possible with handmade contours and extensive calculations.
