Today's question is about using the Phantom 4 RTK for drone mapping. Compared to the Phantom 4 Pro, is the Phantom 4 RTK a better option for drone mapping?

Our caller, Chris from North Carolina has a question about using the Phantom 4 RTK in drone mapping. We have always maintained that the Phantom 4 Pro is the "Honda Civic of Drones". You can use the Phantom 4 Pro across a gamut of applications ranging from photography to drone mapping. Now, is the Phantom 4 RTK more accurate compared to the Phantom 4 Pro when it comes to drone mapping? Is it worth spending thousands of dollars more to buy the Phantom 4 RTK?

To answer, Chri's question we first explain the basic of Real Time Kinematics or RTK. Next, we explain the different variables that affect drone mapping accuracy when using RTK drones. Considering these variables, in which situations will the use of Phantom 4 RTK result in a more efficient workflow and a more accurate output? Other topics discussed on today's show include the importance of using natural markers, difference between relative accuracy and absolute accuracy, the pros and cons of using different RTK drones, the use of natural markers in drone mapping, and much, much more…
