How is the DJI Phantom 4 Multispectral different from the Phantom 4 RTK?

Both drones are RTK-enabled and all-in-one platforms; the biggest difference is the camera. The P4 Multispectral comes with an RGB camera and five cameras that make up a multispectral camera array, all at 2 MP, whereas the Phantom 4 RTK comes with a single RGB camera at 20 MP.
