My goal is to create a KML line and/or polygon where the z-values of the vertices equal the z-values from point data (where the csv has a Z field).
So far, I have created a spreadsheet which, given a couple of data inputs, autogenerates a large list of points (X, Y and Z values). The points can be grouped a few different sections (e.g. poly1, poly2 etc with each poly consisting of 20 or so nodes).
I carefully added fields for the purposes of autogenerating lines and or polygons in QGIS using the Points2One plugin.
So, now I have one layer with a couple of shapes (lines or polygons) using the Points2One plug, but it only provides one z value per shape.
I now also have another layer with a z-value for each node.
What I need to do now is incorporate the two layers into a KML, where the coordinates noted in the code also consists of the z-value.
I saved as the polygon or line layer as a KML. Each shape looks something like this in the text editor:
</Schema>
<Folder><name>experiment2</name>
<Placemark>
<Style><LineStyle><color>ff0000ff</color></LineStyle><PolyStyle><fill>0</fill></PolyStyle></Style>

</coordinates>
</LineString>
</Placemark>
As you can see, all the coordinates are there for the shape (the x,y) but there is no z.
How do I automatically append the z value in the KML such that each vertex also incorporates the z value?????

I've come up with a workflow that works for me.
I feel like there is a much quicker and more elegant way of doing it but it does the job.
Thank you all for your responses!
