In Litchi you can also do what I believe the DJI Waypoints enables you to do … fly a route and create waypoints on the go, etc. … should you want to.
It’s the ability to sit at home and plan a mission carefully that I like about Litchi (particularly in Dec/Jan/Feb!), and take your time to ensure it’s correct before risking your drone, etc.
There’s other free software available (Virtual Litchi Mission - PC Only, or an almost identical Chrome Plugin) that enables you to “fly your mission” in Google Earth (An example), to check camera angles, etc.
As I say, I’ve not used Waypoints, Litchi has been around a lot longer and does all I need - and seems to get the vote by those that have tried both.
