Usage example

The following example converts speed values in the input (in knots for example) into color values. Color values are in the range [0.0, 1.0] for a color gradient from black to white over red and yellow (you can alternatively specify red, green and blue separately).

kmltrack --map-color='float(speed) / 17.0' --map-course=cog input.json output.kml

Example input.json

{'lat': 0.0, 'lon': 0.3, 'timestamp': '1970-01-01T00:00:00.000Z', 'course': 180.0, 'speed': 10.0}
{'lat': 0.1, 'lon': 0.2, 'timestamp': '1970-01-01T12:00:00.000Z', 'course': 180.0, 'speed': 11.0}
{'lat': 0.2, 'lon': 0.1, 'timestamp': '1970-01-02T00:00:00.000Z', 'course': 180.0, 'speed': 7.0}
{'lat': 0.3, 'lon': 0.0, 'timestamp': '1970-01-02T12:00:00.000Z', 'course': 180.0, 'speed': 2.0}
