combining a line with a DEM to create an elevation profile

Question

Hi,

I need to create an elevation profile of a line by combining the line with a high resolution DEM. The goal ist to generate a table with the z values spaced by 1 meter.

I tried to use the profile tool, but this does not work.

Could somebody maybe help me out?

Best,
Lea Schmid

If you are not happy with the proposed solutions maybe there is a way to create a profile table with python?

Don't know if you use python?

Some years ago XanderBakker wrote a script for profile graphs, perhaps it's possible to use this script to export excel tables with the profile data with 1m spacing? The script is here:

You might also use the Divide a Polyline functionality to chop up your line into 1 m chunks and then generate points at each midpoint along that line. Or you could use the Generate Points Along Lines tool which would be faster. You could then extract values to points from the DEM and then the attribute table of your point layer would be your table.

No Problem! This helps a bit, i am able to generate the height, but the distance is wrong...
