My Flight Historian has always used Great Circle Mapper for its maps. However, I’ve occasionally had the need to use other map formats, like GPX (used by many of my mapping projects) or KML (used by Google Earth).
A while ago I wrote some internal methods in Flight Historian’s code to let me generate GPX or KML files. However, they weren’t available for public use.
I’ve changed that with a small update today. Every map on Flight Historian now has download links immediately below it for GPX and KML versions of the map.
