I am not sure what exactly you mean by "sub- layers". If you are
talking about groups, you will find some information in the

I installed the collection, and the QGIS Resource Sharing plugin

of resources, including symbols (markers, line and fill

The NNJoin plugin is perfect for the task, but if you
are using a recent QGIS version, the Processing algorithm
"Join attributes by nearest" (found in the "Processing

Hi Bernd,
It is no problem to use a point layer to define the map areas.
The generated maps will be centered on the points, and the
extent is determined by the specified scale and the size you
have defined for the map on the page.

Hi Dave,
When "Use Z-coordinate for interpolation" is checked, it must be
assumed that the Z coordinate will be used *instead* of the

But it is strange that this should cause the Exception / error
