Tutorial: Create a Longitudinal River Profile

1. Introduction

In this tutorial we're going to create a longitudinal river profile using a DEM and a river layer.

The data provided with this tutorial contrains a filled SRTM 1-Arc Second DEM of the Rur catchment. We're going to download the river line vector from OpenStreetMap using the QuickOSM plugin.

After this tutorial you'll be able to:

  • Download a river from OpenStreetMap using the QuickOSM plugin
  • Sample DEM values for points at fixed distances along the river
  • Visualise the longitudinal profile using the Data Plotly plugin
  • Visualise the longitudinal profile using the Profile tool plugin
