Profile Tool

This tool allows you to interact with elevation data and produce profile lines from various height data. You can then export the output for reports.

Just draw a line on your map, and see the profile it produces from the selected DEM. Below, I've loaded REMA into QGIS and have drawn a segment over Pourquoi Pas Island.

How to create a Terrain Profile:

1. Load the DEM into QGIS, and select this layer in the Layers Panel

2. Press the “Profile” tool button. This opens the panel consisting of a graph on the left and a raster layer list on the right. The DEM you had selected will be added to the raster layer list.

3. If you have “Selection: Temporary polyline” enabled in the plugin Options, you can draw a line in the map area. Click once at the start of the line, then double-click to stop drawing the line at the end.

4. After you have finished drawing the line, the graph will display the profile.

How to create a profile for an existing feature

1. Change the selection mode from “Temporary polyline” to “Selected polyline”.

2. Select the vector layer which contains the line feature you want to use in the QGIS layer list.

3. In the Map View, click on the line feature you want to generate the profile from.

This tool plots profile lines from raster layers or point vector layer with elevation field. Supports multiple lines as well as graph export to svg, pdf, png or csv file. Supports 3D polyline export to dxf.
