Self-refreshing NetworkLink feeds for Google Earth. Each .network.kml
points at the hosted data file and re-fetches hourly, so opening it once keeps the layer current.
The raw .kml data file is also linked for one-off imports (e.g. Google My Maps).
Prefer an in-browser map that auto-refreshes? The live trip maps
render these feeds with the Google Maps JS KmlLayer, which follows the
NetworkLink and re-fetches hourly — the auto-updating view that My Maps can't give you.
Google Earth (auto-refresh): open the .network.kml URL, or download it and
open the file. Earth follows the NetworkLink and re-fetches the data hourly.
Google My Maps (one-off import): use the raw .kml link instead —
My Maps does not follow NetworkLinks. Add layer → Import → paste the raw URL, and choose
"Add more items" to append without overwriting. Re-import after syncing your sidecar.
