| Mavic3M NDVI imagery is really good, but takes a bit of practice, and in some cases ground truthing, to make it accurate. Fly low, use RTK, and don't use Terra (it's cheap for a reason). Pix4D is really good, and there are other more expensive options that people swear by like Agremo or Solvi. The latter 2 are more automatic in a way where Pix4D is still a lot of user input to create a prescription.
Once the crop is to a certain height, it'll be more difficult to actually make a weed map. | |
