2/3 To make the KMZ files in my prior post I used #GISsurfer to take a series of screenshots that exactly adjoin. Each screenshot is 100% map. GISsurfer provides the georeference data.
Then I used photo editing software to stitch the screenshots together. Easy to do since the screenshots exactly adjoin.
Windows file manager was used to make the KMZ file by combining KML syntax (provided by GISsurfer) and the finished image.
