I just published a step-by-step tutorial on building a Digital Elevation Model and generating contour lines in QGIS using Natural Neighbor interpolation through SAGA. What's covered: - Importing elevation data as a Point Z layer - Enabling the SAGA processing provider in QGIS - Running Natural Neighbor interpolation to generate a smooth DEM - Styling the DEM with a terrain pseudocolor ramp - Generating contour lines using GDAL Contour - Adding curved elevation labels Watch here: https://youtu.be/ujRMjBDjvUk Happy to answer any questions in the comments!
