KML controls

Several buttons on the prediction page are associated with the KML (prediction path):

The globe button (or pressing k) toggles whether the KML (occultation prediction) overlay is shown on the map or not. Turning it off can make the underlying weather more visible when the KML lines are close together.

The letter-A button (or pressing l / "el") toggles whether labels for KML points are shown or not.

The inward-pointing-arrows button (or pressing i) toggles the size of KML icons. By default they are shown normal size, but toggling the button makes them smaller, revealing more of the surrounding weather imagery.

Map features

The overall KML name and description are shown below the GUI controls (below the imagery timestamps). Hovering or clicking on a map KML element (e.g. a line or icon/point) highlights it on the map, and shows its details -- layer name/description and placemark name/description -- in the below-GUI KML info area. Clicking anywhere else (e.g. map or page background) un-highlights the currently-highlighted KML element (if any).

A point placemark, when highlighted, also has some location info shown in the KML info area: its latitude/longitude; a Google link to open it in Google Maps in a new tab; and an LPM link to open it at lightpollutionmap.info. Both maps are the same scale and center location (once sidebars are closed), so they can be "blink compared" by toggling their browser tabs back and forth.

The KML, if available, may be downloaded via the settings dialog (see the Settings help page).
