I assumed this was just a stored z value, but it may be just an attribute called 'Z' I guess... What is the difference? And how would I extract it for each vertex via PyQGIS? | |

| Nov 18, 2020 at 14:40 | comment | added | sdunnim | @BERA I have been able to extract the vertices into a layer; I'm now trying to extract the x,y,z coordinates of each point (this is easier for me than going through the raster method), but can't get it to work. I have followed a couple of the answers from the following link, but nothing is getting printed to my console: gis.stackexchange.com/questions/53594/… | |
