Why Geographic Information Systems Stack Exchange recommends it
GIS Stack Exchange users cite it as the walkthrough they followed for making contours and a DEM from Google Earth data, usually when asking why a step such as natural neighbour interpolation fails.

What it is
A roughly 11 minute QGIS 3.14 tutorial showing how to build a DEM and contour lines for a custom area. It draws a path in Google Earth, converts the KML to a text file with elevation data on GPS Visualizer, then interpolates a raster in QGIS. It is published by the Geoinfo_Tech Bytes channel (Geospatial Information Hub).

I am having trouble with the following: For a project I need a topographic map with contour lines of a specific area. I've googled around and the only suitable option (without buying expensive software subscriptions) I could find was using QGIS. I am running Version 3.16.1 Hannover. I followed this tutorial: [this video] (Time Stamp 4:34) I created a raster using the path option in Google Earth Pro and then added elevation data from [LINK] , downloaded that as a CSV and imported it through Add Layer > Add Delimited Text Layer. No problems until here. But when I try to run the natural neighbour tool I always get the same error, no matter what I do: QGIS version: 3.16.1-Hannover QGIS code revision:

I followed this tutorial [this video] and when performed from minute 5 to 5:39 I got black polygon. Path is created in Google Eart , exported to kml, in GPS visualiser conveted to txt. Added as delimited layer in QGIS which imports just fine.

I'm using QGIS and trying to create a DEM using this tutorial: [this video] I'm getting error messages when trying to run "natural neighbor" with my file of coordinates. I pasted the error log below, as well as the screenshot for the settings I used. Do you know what is causing this error?
