QGIS 101: Contour Lines from 30m DEM

*** This video is dedicated to Abu Asal, who passed away last week in Amman/Jordan. *** In this video I will show you how to prepare contour lines from a set of regular data points – the SRTM 30m elevation model - which is a raster data set. You will learn: - How to find the correct DEM for your project area. - How to set up a topography colour ramp & enhance it to show the local topography. - How to smooth the DEM raster using the Gaussian filter from SAGA. - How to extract contour lines from the smoothed DEM. - How to use the Geometry Generator to hide some contour lines. - How to use the Geometry Generator to control contour line thicknesses. - How to label the contour lines with custom formatted text. - How to save the contours and formatting inside a QGIS GeoPackage file. - How to save the settings in a Layer Style File, so you can use it for other projects.
