I am planning out a mapping mission in Mission Planner on my CrystalSky. The site is a 50 acre Solar Farm which I normally break up into several smaller missions. The crystal sky is using map box and the the site is not on the image. The site is over 6 years old and on google maps. Is there a free mission planner that I can create the KML files on now so I don't have to waste that time in the field manually mapping it out
