In this tutorial, we teach you step by step how to generate contour lines from QGIS software using a Digital Elevation Model (DEM) as input geographic data. It is worth noting that it is not possible to extract contour lines from optical images such as Landsat, Sentinel-2 and CBERS-4A, as they do not contain altimetric information. Contour lines are used in the production of maps and various Geoprocessing projects in areas such as urban management, environment, civil construction, among many others.
