Google Earth is a fantastically powerful product that Google has alas forgot. The KML markdown syntax provides a way to animate a path, but it isn't easy - it's a painful manaul process.
This tool builds off this great work to allow the input of a Google Earth Path KML file, and in return receive a tour KML file back.
It looks for a single <coordinates>
entry with space-separated coords. Means you can draw a path in Google Earth, export to KML, use this tool to generate a tour, then animate this path.
###Install
npm install -g tourify
###Simple input
tourify --input=examples/input.kml
# will output a new kml file "tour.kml"
###CLI Options Not many right now - but you can specify the step size (aka speed).
tourify --step=0.01 --input=examples/input.kml --output=mytour.kml
