I have a .jpg screenshot of a Google-Earth Pro view and see that r.in.gdal
supports that file format. However, I have no idea how to structure the
command line for the task.
On the GE view I recorded the geographic coordinates of four
readily-identifiable points and can put them in a v.in.ascii point file for
import
My web searches for the process of saving a GE view as an .kml file were
without success. That would be another option for importing the GE image and
using it as the background for additional layers outlining specific areas.
Pointers to appropriate modules is appreciated.

Hi Rich,
A maybe-easier workflow is to load QGIS with an XYZ Google Satellite base layer, then save to image *with a World File*. That should allow easy import into other tools. https://geogeek.xyz/how-to-add-google-maps-layers-in-qgis-3.html

Ken,
Good idea. I know that qgis and saga gis can use GE images as raster
underlayers and haven't seen an example using grass. I'll look into learning
qgis.

How about:
i.gcp - Manages Ground Control Points (GCPs) non-interactively.

Markus,
That looks like a good suggestion. I appreciate it.
