With this new tool you can export the profile as image (PDF or jpg) but not as table of values. It can not be used to estimate slope (linear regression). So Terrain profile plugin, or other terrain analysis algorithms, are still valuable in my opinion.
are these 'no data' value pixel mainly because of object on the ground (e.g., building) as DTM only represent the bare ground value? thanks in advance for the answer.
They can't be used for DEM analysis. Algorithms assume that x and y coordinates are in the same units as the z, which isn't the case with lat/lon in degrees and z in meters.

thank you. thats what i need for my exercise
Thanks for the video

I agree that the Profile Tool plugin is still useful.

In this case the building footprints were filtered out and left nodata pixels at those locations.
I’m getting page not found when I click the link
Is there point cloud download for asia? Especially for phillippines?
How come geographic coordinates can’t be used for analysis?

@@HansvanderKwast gotcha! Makes sense. Thank you!
