I'm accessing the Index plots for Ordnance Survey map sheets, provided as a KML by the Charles Close Society here: https://www.charlesclosesociety.org/indexes (scroll to the bottom of the page for the KML download).
And loading the file to Google Earth, where it is possible to view all the Index plots overlayed in one big jigsaw, or view one at a time.
I would like to export one of the layers only, import to ArcGIS 10.+ and convert from KML. Although I'm viewing only one layer when I try to export, I'm still getting all the data in the exported file. Rather than the single layer I need.
