QGIS elevation profile/cross section tool -- a deep dive!
Ғылым және технология
QGIS 3.26 is introducing a mountainload of new functionality for handling elevation and height data in your projects! In this stream I'll be exploring all these new features in depth, and looking at how you can use QGIS to analyse height data from vector, DEMS, point clouds and mesh sources.
Apologies for the poor stream quality and the dropouts! Unfortunately some of the "thank yous" at the end were also cut off due to a disconnect, but credit here belongs to:
- Lutra Consulting, for organising the crowdfunding campaign which made this possible (www.lutraconsulting.co.uk/cro... for details)
- North Road Consulting (north-road.com/) who implemented the profile tool support for QGIS
- Hobu (hobu.co/), responsible for the underlying point cloud handling improvements and support for cloud optimised point clouds.
- All the backers of the "Enhancing elevation data and point clouds in QGIS" crowdfunding campaign!

Thank you for the amazing session. Awesome stuff. Just what I was looking for, been trying to explore point cloud data from photogrammetry in QGIS.
This is really great, thanks for this! Nicely done.
37:10 Thanks for mentioning this! I think this would be nice thing to use when you have a route and also want to know the elevation changes along this route. I did a some kind of UAV tracker including video player widget and polyline layer. Implemented a rubberband tracking point that goes simultaneously with video slider position. The live elevation profile feature is very, very cool stuff and I think it's 'engine' can also be used in various tasks! Thank you for making it!
Great to see how easy it is to create a profile and style it!
Nice addition to QGIS, is there an option to export it in svg format in the near future?
Cool stuff
In terms of temporal use of the elevation charts - one could create several temporal layers and create several charts that are then exported and used to create an animation in GIMP or Blender.
We have 3.30 qgis version now with Elevation Profile in Print Layout. But how I can choose a DEM and a line layer from the qgis main window to obtain the Elevation Profile in Print Layout?
Thanks for the video. HOw to save pdf in a scale?
How can I change the horizontal scale for example from kilometers to miles?

Fantastic work Nyall. Is it possible to control the vertical scale. For instance 1:1 scale as an override.

Thanks for the video! Is there anyway to provide a legend in the plot export?

Great work! I have some problem to get elevation data in table view and export it, is it possible?

That's not supported in 3.26 -- hopefully in a future version 👍

@@NyallDawson Awesome - this will be key to me adopting this new Profile Tool. It's looking great so far though.
can we print this elevation profile ?

You can export the plot to pdf (or svg, PNG, etc), and print from those 👍

@@NyallDawson is it possible to save output in dxf format, because in the documentation its shown that output can be saved as dxf file, but I haven't found any button.. docs.qgis.org/3.34/en/docs/user_manual/map_views/elevation_profile.html
