In this QGIS tutorial, we will walk through the process of calculating the volume of a mountain using the Raster Surface Volume plugin. We start by creating and filtering contour lines, followed by converting them into lines and validating the data. Next, we generate polygons, mask, and clip the raster data, which forms the basis for our final volume calculation. This step-by-step guide is perfect for those looking to perform terrain analysis and volume estimation within QGIS. Whether you're working on elevation data or learning to use GIS tools, this tutorial has you covered.
Topics covered:
Creating and filtering contour lines
Converting contour lines to lines
