Requisitos de conclusão
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
